For many years, sport anglers relied on lead weights to carry their lures to the bottom of a lake or river. However, biologists discovered that the toxic nature of lead posed a threat to aquatic life. Lost lead weights had begun to pollute the lakes and rivers. Fortunately, a safer alternative was found and, today, lead weights have been largely replaced by tungsten. If you are using a tungsten weight, you should paint it to camouflage the shiny surface before casting your line in the water.

Instructions

1
Clean the tungsten weight with a cloth and some rubbing alcohol. Allow it to dry.

2
Paint the weight in the color you've selected. Use enamel metal paint and a small paintbrush or strong nail polish and a nail polish brush. Let dry thoroughly. Apply a second coat.

3
Inspect your collection of tungsten weights before each fishing trip. Over time, the paint will begin to flake with repeated use. When this happens, sand off the flaking paint and reapply a new coat of paint, following the steps described above.

Tips & Warnings
Tungsten is a very dense and strong metal. Because the surface of a tungsten weight is so strong and smooth, the surface cannot be roughed up using normal tools and the paint will not adhere to the surface as well as it would to other metals.

Tungsten Iridium Stream Mouth
                  ---a special tungsten heavy alloy (WHA) part
The tungsten iridium stream mouth is as a special tungsten heavy alloy with other refractory metals. It mainly uses in rare-earth metal smelting, the induction furnace heating element, the quartz glass smelting and so on, makes the high temperature vessel.

In the glass and the ceramic industry, the tungsten class mouth is a ceramic micro production very essential part. The tungsten proportion is big, degree of hardness is big, the heat conduction electric conductivity good, heat-resisting, wear-resisting, anti-corrosive, has the low expansibility and the size stability under the high temperature. The tungsten melting point is highest when all metals (reaches as high as 3380 degrees Celsius), the steam tension to be lowest, the tensile strength is highest (1650°C), and its antiseptic property is good, the majority inorganic acid are very small to its corrosion.

Therefore it when manufactures the heavy metal alloy is ideal. But the tungsten and the iridium make the alloy, its abrasion resistance, degree of hardness, the intensity, the heatproof quality obtained the further promotion, thus has guaranteed the product uniformity well. Is precisely these precious performance, causes it to become now in the high-tech crystal glass industry the indispensable equipment component.

Tungsten film is used for studio photography. The color temperature of average daylight is 5,000 degrees Kelvin. The term "tungsten" refers to a color temperature of 3,200 degrees Kelvin. Therefore, tungsten film is designed to be used under studio lights of the same color temperature, called tungsten lights. If you use tungsten film outdoors instead of under tungsten lights, your photos will have a blue cast. Similarly, if you use a different type of film under tungsten lights, your photos will have a gold cast.

Instructions

1
Store your tungsten film in a dark location so it is not damaged by light.

2
Open the back of your camera and, while still in a dark location, place the tungsten film into the cylinder hub so it clicks in place and pull the leader of the film until it wraps slightly around the hub on the other end of the camera.

3
Close the back of the camera, turn the camera on and listen to the film load. If you do not hear a loading noise, you may have to open the camera and pull the leader a bit farther. Once the film is loaded, turn your camera off until you are ready to use it.

4
Situate your subject or props in the area where you plan to take photographs in your studio.

5
Set up your three tungsten lights on stands so your subject or props are evenly lit. You may have to move around the lights and raise and lower the stands until you reach the perfect lighting. Use light umbrellas if the lights are too bright for your space.

6
Turn on your camera and take photos as you normally would. When your film roll is complete, store it in a dark location and follow Steps 2-3 to reload your camera with another roll.

Tips & Warnings
Tungsten film can be purchased in most photography supply stores and is developed in the same way as any other type of film.

Nowadays, tungsten heavy alloy is increasingly adopted as the raw material to make parts of military products, such as bullet, armor and shells, shrapnel head, grenade, hunting gun, bullet warheads,bulletproof vehicles, tank panzers, cannons, firearms, etc. A major use for tungsten heavy alloys is in kinetic energy penetrators, where they are in direct competition with depleted uranium (DU).

Recent investigations conducted at the Army Research Laboratory show that DU’s superior properties resulted from its ability to localize shear during ballistic penetration events. Therefore, it was argued that if localized shear can be imparted to tungsten heavy alloys, these alloys would exhibit penetration performance matching that of depleted uranium (which had become an environmental problem).
