Tungsten rings and stainless steel rings are both cost-effective alternatives to the more expensive gold and platinum selections. However, there are differences between them to keep in mind depending on your needs and budget.

    Durability
        Tungsten and stainless steel rings both resist fading, rust and corrosion. Neither metal will stain the body. Tungsten is a much heavier metal than stainless steel, and is therefore stronger and harder to scratch. However, stainless steel is durable enough to hold up to daily wear with proper care.

    Style and Finish
        Both types of rings can be given a variety of styles and finishes. Due to its superior strength, a tungsten ring's polish and finish will outlast that of a stainless steel ring.

    Sizing Options
        Neither type of ring can be resized. Tungsten rings are readily available in most sizes, even in hard-to-find half sizes. It can be more difficult to find the right size in the desired style of stainless steel ring.

    Financial Considerations
        Costs for both types of rings can vary widely, but stainless steel is less expensive. A 2010 search on Amazon.com found an 8mm flat band tungsten ring for $29.95 and a comparable sterling silver ring for $5.22. At the national jewelry retailer Zales, a sterling ring went for $119, and a comparable tungsten ring was just under $280.

Tungsten is a popular metal used in rings for men and women because of its high quality, being nature's hardest element and having a melting point of 6192°F. These characteristics are what make tungsten carbide virtually scratch proof and extremely durable according to Tungsten World.

    Jewelry Stores
        Tungsten carbide rings are sold in jewelry chain stores around the world today. Tungsten carbide rings range in price from about $200 to $900, depending on their style and if there are inlays of diamonds.

    Online
        The Internet has many sites selling quality tungsten rings. There are tungsten carbide wedding bands, tungsten Inlay bands, and black tungsten bands. These rings range in price from about $150 to $1,000.

    Auction Sites
        There are many auction sites on the Web, where you can search for tungsten ring or wedding band and find many auctions going with lower prices than you may find in a jewelry store or an online site. Some have tungsten ring bids for as low as $50. Keep in mind that tungsten rings can not be sized so make sure you have the correct measurement for your finger before ordering.

Chosen for its durability, scratch resistance and beautiful silver color, tungsten rings are a popular choice for wedding bands and men's fashion rings. Tungsten is five times harder than steel and 10 times harder than 18 karat gold. This rugged durability makes tungsten rings ideal for people performing manual labor who wish to wear jewelry while working. If you need to remove a tungsten ring because of an emergency, medical or otherwise, you can remove it with common household tools. This is not difficult but it may destroy the ring. When the ring is cut, the metal will shatter.

Instructions

    Tight Tungsten Rings

        1
        Place the ring finger under a stream of cool water. The cool temperature to reduce swelling of the finger.

        2
        Apply liquid soap to the ring finger. Rub the soap around the ring and finger to lubricate the ring. Gently twist the ring from side to side to lubricate the underside with soap. Liquid soap will not damage tungsten.

        3
        Gently pull the ring toward the knuckle. Work the ring down the shaft of the finger until it slides off.
 
        4
        Seek medical attention in the event of an emergency. If the tungsten ring is cutting off circulation or causing pain, go to a hospital.

        5
        Prepare to remove the ring yourself. If medical assistance is not available, a tungsten ring can be shattered and removed from the finger with a pair of vice grip pliers.

        6
        Place the vice grip pliers around the ring. If the ring is bent into an oval shape, place the pliers on the long sides of the oval.

        7
        Apply a quick squeeze of pressure to the ring. Tungsten will fracture into pieces and fall away from the finger.

        8
        Look for cuts or wounds on the finger. Clean the wound with water. Apply an antibiotic ointment and bandage the wound. Seek medical attention as soon as possible if stitches are needed or if the blood is not clotting at the wound site.

Carbide is a word that refers to a variety of carbon compounds. While there are several different types of carbide, tungsten carbide is the type most commonly used for cutting or drilling tools; it is very hard, relatively inexpensive, and will retain a sharp edge for a long time. While tungsten carbide is noted for its remarkable durability, a tungsten carbide tool may need occasional sharpening if it is used regularly.

Instructions

        1
        Determine if your tool needs sharpening. One easy way to decide if your tool is becoming dull is to see if it reflects light well. Shine is an indication of wear. You can also gently scrape a fingernail on a blade and see if it shaves off a sliver; if it does not, the blade is dull. Touch is not necessarily a good way to determine if a blade is sharp, as a dull carbide tool may still feel sharp.

        2
        Find a professional sharpening service. Sharpening carbide is not recommended for non-professionals, as it requires skill and specific sharpening machinery. Imprecise sharpening can ruin a tool, and a professional can restore a blade to like-new condition.

        3
        If you are interested in learning how to sharpen blades yourself, it is recommended that you locate a teacher.

        4
        Carbide tools require diamond for sharpening, due to their hardness. Wet grinding using an abrasive wheel on an automatic grinder is a very precise method of sharpening. It is also possible to sharpen a tool by using a diamond lap, but this is very imprecise and time-consuming.

Sharpening a tungsten ensures that the arc of your tig weld remains small and symmetrical. If you attempt to weld with a blunt-tipped tungsten, the resulting weld will look sloppy and drift outside the ideal welding site-line, and the tungsten will begin to arc itself to the weld and stick. Sharpening a tungsten is simple, and completing this process will ensure that each pass you make with your welder is fluid. Does this Spark an idea?

Instructions

        1
        A wheel grinder is the fastest way to sharpen your tungsten. 

        Put on your safety glasses and welding gloves. Remove the tungsten from the welder's torch and turn on the wheel grinder.

        2
        Hold the tungsten against the grinding wheel lightly. The wheel will grind the tungsten quickly, so there is no need to apply a lot of pressure. The angle of the tungsten should be 15 degrees parallel to the grinding wheel. You want your tungsten to have the same look as a freshly sharpened pencil.

        3
        Rotate the tungsten in your fingers as you hold it against the wheel at a 15-degree angle. Twist the tungsten all the way around several times until the end is a sharp point, the neck of the tungsten's point tapering in about 1.5 inches from the point.

        4
        Check your work. When you are satisfied, wipe the end of the tungsten clean with a rag to remove all debris. You are ready to begin tig welding again.

Accurately measuring your finger for its tungsten ring size is pretty simple. There is a standard North American conversion scale, and the same scale is used for both men and women. Note that it's best to measure your finger later in the day; fingers do swell a bit and you might have trouble removing a ring if you don't take this into account when sizing it.

Instructions

        1
        Cut a thin strip of paper.

        2
        Wrap the paper around your finger. Make sure the paper is below the joint of your finger and close to your knuckle.    
       
        3
        Mark the spot where the paper meets and measure the distance with your ruler.

        4
        Use the following chart to determine your  tungsten ring size. Rings also come in half sizes, the measurements of which, of course, will fall somewhere in between the whole sizes.

        5
        If you're still in doubt, download a printable ring size chart. Many online jewelers offer these, and their charts might be slightly more accurate for their particular  tungsten rings.

       Alternatively, go to the jewelry counter at your local discount retailer, such as K-Mart, Target or Walmart. You'll get a fitting without the pressure to buy that comes with going to a jewelry store.

Tips & Warnings

    Printable ring size charts can help you surprise a loved one — you simply match an existing ring to the circle representing the correct  tungsten ring size.

A sturdy, durable metal, tungsten is used to make rings designed to last a lifetime. However, this durability can prove a downfall: Unlike other metals used in rings, which remain malleable over time and can be adjusted to fit changing finger sizes, tungsten is impossible to remold once it has been formed and forged into a shape. Jewelers design tungsten rings for comfort fit--meaning, an extra curve in the design makes them run a half size larger than most rings. Accurately determining your ring size and adjusting for tungsten's characteristics can provide you with a comfortable and durable ring. Does this Spark an idea?

Instructions

        1
        Measure your ring size when your hands are warm and you have been active for at least a few hours. Activity and temperature can change the size of your fingers, and fingers are at their largest when they are warm, especially toward the end of the day.

        2
        Try on multiple rings or ring sizers at a jewelry store, or print a ring sizing chart from an online retailer. Find the ring size that fits comfortably and snugly at the very base of your finger. This is your normal ring size.

        3
        Subtract a half size from your normal ring size to determine your tungsten comfort fit size. For example, if your normal ring size is an 8, your tungsten size is 7.5.

Tips & Warnings

    If you already know your regular ring size, simply subtract a half size to determine your tungsten size.

    Some jewelers will have the option for you to try on "comfort fit" ring sizers. If you use a comfort fit sizer, do not subtract the half size, as the comfort fit is the exact design of the tungsten ring.

    Tungsten rings cannot be reshaped. If you provided or received the wrong ring size, contact your manufacturer or retailer for replacement options.

Tungsten lighting is a term used by photographers to distinguish from fluorescent lighting or strobe lighting. Tungsten is a type of incandescent lighting using a bulb with a filament made of the metal tungsten, as opposed to, say, carbon or platinum. Unless you have switched to compact fluorescents, most of the lighting in your home is tungsten. In still photography, tungsten lighting gave studio photographers greater flexibility than the classic north sky light. Tungsten lights reigned supreme for many years in commercial studios until the introduction of strobes (or speed lights) and some workers still prefer tungsten for its controllability (what you see is what you get). For television and cinematography tungsten is essential.

Tungsten lamps specifically for photographic purposes are made to very tight tolerances since most photography or cinematography today is done in color. For photography, tungsten lamps are produced in two types, having very specific "color temperatures:" type B lamps, the most common, have a color temperature of 3200 degrees Kelvin (3200°K); type A lamps had a color temperature of 3400°K and were matched to Kodachrome Type A (ASA/ISO 40). This material is now discontinued and so far as I know there are no other Type A still stocks on the market.

Without getting too tediously technical we should try briefly to explain "color temperature:" The higher the color temperature, the bluer the light. The lower the color temperature, the more yellow to red the light. Noon daylight (sun shining, no cloud cover) in the area of the globe between the tropics is considered for practical purposes to have a color temperature of 5000 degrees Kelvin (5000°K). "Daylight" color films, or your default setting on your digital camera, are balanced for ±5000°K. Electronic flashes ("strobes" or "speed lights" or the little strobe on your camera) have a nominal color temperature equal to noon daylight. All other light sources have different color temperatures and theoretically require some sort of compensation to render "true" color, either by filtering the film or the light or by changing the film or settings on the camera. If you are using studio quality tungsten lighting, you should also use a type-B incandescent balanced film, or set your digital camera for either AUTO or incandescent. In practice, plain household tungsten lighting (color temperature around 2800°K) will yield a perfectly acceptable photograph with a type-B film or with your digital camera set on auto or incandescent.

Most 3200°K studio lamps used today are tungsten halogen. Halogen lamps have quartz envelopes and are filled with a halogen gas such as iodine or bromine. The gas combines with the evaporated tungsten from the filament during use and helps some of the tungsten plate back onto the filament when it cools, lengthening the life of the lamp. The quartz envelope does not darken over the life of the lamp, so the color temperature does not significantly change, nor does its brilliance.

"No One In UK Safe As Big Chill Sets In," warns Sky News. BBC is less apocalyptic but, still, prepare for demand for ice tyres.

"Forecasters predict up to two weeks of wintry weather, with plummeting temperatures and snowfall possible in many areas," warns Sky News. The BBC is not so flustered: "this week may begin a transition to some colder weather. The rest of January looks as though it may continue to bring colder than average temperatures with an increased risk of some snowfall."

But if there's a long period of ice and snow in our future, bike shops should be prepared for a spike in sales of bike tyres dotted with tungsten carbide studs. Stocks of studded tyres are likely to dwindle as the cold weather approaches.

Gritted roads may be safe to cycle on but not all roads get gritted. And unlike in the Netherlands, very few bike paths in the UK get gritted (and even fewer are heated). So, more and more cyclists who wish to keep commuting by bike are now using tyres studded with 'spikes'. In previous cold snaps studded tyres from brands such as Nokian, Conti and Schwalbe sold out very quickly.

The Schwalbe supplier in the UK - Bohle - supplies studded tyres for MTBs, 700c road and cross bikes, and some folding bikes. Cambrian Tyres stocks spike tyres from Continental: the Spike Claw for MTBs and Nordic Spike for 700c bikes.

In 2010, an NHS study found that falls on black ice are a major cause of bike crashes. The study - by NHS Bristol - was the UK’s largest and most comprehensive survey into non-collision cycling incidents, ie crashes that do not involve another road user.

The survey revealed that slipping on ice is the most common non-collision incident, being mentioned by 26 percent of respondents. The next most common incident noted was slipping on wet roads, with 8 percent of reported incidents.
