To make a tungsten carbide ring, you should ground tungsten and carbon are poured into a metal die cube containing a ring mold. The mold is subjected to high pressure to push the powder together into a solid ring blank. The blank is then fired in an oxygen-powered furnace at temperatures exceeding 6,000 degrees Fahrenheit. Only at this obscenely high temperature will the blank's component elements intermingle and solidify as one. Once cooled, any burs or extra metal is removed with high-powered diamond edged saws. Diamond powdered files and sanders are then used to polish the ring until it shines.

With this done the ring is ready to be worn. It should be noted that since such rings cannot be re-sized, each one must be constructed to order if it's to be a perfect fit.

There are benefits and considerations linked with tungsten rings and titanium rings . Consider all aspects before making a purchase.

1. Properties. Both materials used in the construction of rings are very hard, but tungsten carbide is harder; only a diamond can scratch a tungsten carbide ring. In terms of weight, titanium is 43 percent lighter than stainless steel, while tungsten carbide is 90 percent heavier, according to Titanium Kay.

2. Cost. A tungsten carbide ring will cost more than a titanium ring, due to high production costs. Tungsten carbide can only be manipulated to form rings in temperatures exceeding 6,000 degrees Fahrenheit.

3. Facts. Tungsten carbide is much less ductile than titanium. Under excessive pressure, a tungsten carbide ring will fracture or shatter into several pieces, whereas a titanium ring will bend. Some people may experience allergic reactions while wearing tungsten carbide rings. New Jersey's Department of Health & Senior Services claims that exposure to tungsten carbide can cause lung problems.

Tungsten carbide -- made from carbon and tungsten -- is easy to recycle, and very much in demand around the world.

1. Find a scrap metal collection center near you. A great place to start is with your city or county waste management office. Often, these offices will have searchable databases online, allowing you to type in your location and the type of materials you have to search for collection centers near you. Since scrap metal does fetch you (and the dealers) some cash, you're likely to find several scrap dealers near you.

2. Weigh your tungsten carbide pieces, to get an idea of how much you have. If the amount is too large to put on a scale, measure the material's height, width and length to get a rough idea of how much you have.

3. Check around for the dealer offering the best prices. If you have several scrap metal centers near you (which most metropolitan areas do), the various companies may offer different prices in order to stay competitive. Tell them how much you have, and ask for a ballpark figure on how much you'd get for it. Or simply ask them how much they're paying per pound or ounce. Once you've found the center with the highest price, note their drop-off hours and any special documents, such as identification, you need to bring with you.

4. Load your tungsten carbide onto a truck and take it to the scrap dealer, making sure to bring along the proper documentation. When the dealer accepts your materials, you should receive a check. Dealers typically do not pay cash, due to laws designed to stop metal theft.

Tungsten carbide tools are graded based on their hardness and composition.

The grading system ranges from soft to hard and brittle to tough. Some machining applications call for a carbide tool that is made of very hard, but brittle material that can hold an edge.

Other applications call for material that can resist shock and is softer and tougher. By varying the proportion of the cobalt used as binder, and by using different metallic carbides, the properties of the cemented carbide can be managed.

1. Hold a magnet to the item you are examining. If the magnet is attracted to it, the item is not tungsten carbide, it is iron or steel. However, sometimes tungsten carbide is used as a tip for an item, particularly saw blades, so this test is sometimes misleading.

2. Pick up the item and "heft" it. Tungsten carbide is very dense, and a tungsten carbide object will feel very heavy relative to its size. If you have a piece of steel that is a similar size to the object you are inspecting, the item will weigh about twice as much as the steel if it is carbide. This is the most conclusive test that does not risk damaging the item you are examining.

3. Scratch the item with a steel nail. The Mohs hardness scale is a method of measuring the hardness of different materials. Steel has a Mohs hardness that ranges between 5 and 8.5. Tungsten Carbide will range between 8 and 9, depending upon the exact alloy that the carbide is made from. Typically, tungsten carbide will scratch steel and will not be scratched by steel. Tungsten carbide will scratch glass as well, as another way to test its hardness.

4. Examine the item. Tungsten carbide does not corrode under normal conditions and does not rust. Seeing either of these indicates that the item is made from some other metal.

5. Put the item to a grinder and watch the sparks. Sparks from tungsten carbide are short and dark red, and are very distinctive to carbide. This is a fairly definitive test, but is somewhat more dangerous than other methods of identification and can damage the item.

1. Machining. Machinists frequently use tungsten carbide tools to machine other hard metals, such as stainless steel. When they are manufacturing machine parts, the material that they are constructed from must be hard and resistant to wear. This makes milling or machining these metals that much more difficult, and, as such, must choose a material harder than the material to be machined. Tungsten carbide fits this bill perfectly.

2. High Production. When producing a large number of units in an industrial setting, the mechanisms that are stamping or machining the parts should be long-lasting and resistant to wear. For this reason, even when the machined material is not particularly difficult to work with, use tungsten carbide due to its longevity. It is subject to chipping, however, and is frequently coated with another material.

3. High-Speed Tools. In industrial applications where tools will be used at a high rate of speed, high temperatures inherently follow. Tungsten carbide is resistant to extremely high temperatures, making it ideal for situations where tools and mechanisms are needed to perform in these high-heat applications. This makes them useful for grinding tools and metal milling bits.

4. Torch and Welding Tips. Tungsten carbide is used for acetylene and other torching applications where you need a material that can retain its properties under constant exposure to flame. It is also useful in welding applications where a metal is exposed to high heat but cannot bond to the material being welded.

Manual metal arc welding was first invented in Russia in 1888. It involved a bare metal rod with no flux coating to give a protective gas shield. The development of coated electrodes did not occur until the early 1900s when the Kjellberg process was invented in Sweden and the Quasi-arc method was introduced in the UK. It is worth noting that coated electrodes were slow to be adopted because of their high cost. However, it was inevitable that as the demand for sound welds grew, manual metal arc became synonymous with coated electrodes. When an arc is struck between the metal rod (electrode) and the workpiece, both the rod and workpiece surface melt to form a weld pool. Simultaneous melting of the flux coating on the rod will form gas and slag which protects the weld pool from the surrounding atmosphere. The slag will solidify and cool and must be chipped off the weld bead once the weld run is complete (or before the next weld pass is deposited).

The process allows only short lengths of weld to be produced before a new electrode needs to be inserted in the holder. Weld penetration is low and the quality of the weld deposit is highly dependent on the skill of the welder.

In the tungsten carbide ball tooth drill head selection, there are several shapes: hemispherical gear, bevel gear, parabolic tooth, wedge-shaped teeth.

Hemisphere teeth enough hydraulic rock drill impact energy, energyutilization is high, the effect of rock breaking, extremely resistant alloy teeth. Cone-toothed alloy ball gear is easy to chisel into the rock drilling rate higher impact energy (wind pressure of wind power rock drill, hydraulic rock drill performance change) bevel gear work more effectively, but poor abrasion resistance. Parabolic ball gear between bevel gear and hemispheric is of foreign alloy plant or joint-venture factory production and use.

The wedge-shaped ball gear is suitable for hard and abrasive rock.

Tungsten carbide studs are commonly inserted in snow tires in areas with a lot of snowy or icy weather. Tire studs increase traction in bad road conditions caused by the bad weather.

When the bad weather has passed and the tires are driven on the road, the tungsten carbide studs are very noisy and cause damage to road surfaces. Thankfully, tungsten carbide tire studs are removable so that snow tires can continue to be used without dealing with the noise or damaging the highways.
