Pure tungsten is a steel-gray to tin-white metal. Tungsten has the highest melting point and lowest vapor pressure of all metals, and at temperatures over 1650°C, has the highest tensile strength. The metal oxidizes in air and must be protected at elevated temperatures. It has excellent corrosion resistance and is effected only slightly by most mineral acids. Contrary to popular belief, pure tungsten is not all that hard. In fact pure tungsten is soft enough to be cut by a hacksaw. While tungsten itself is not as hard as people might think, a tungsten compound called tungsten carbide, is extremely tough and is used in drill bits, high speed cutting tools, and mining machinery.
This is tungsten
This is just regular tungsten in ore form. It will be turned into the things listed to the right.
This is what tungsten is used for
Tungsten that has been alloyed with steel is used in rings/wedding bands, cars, filaments for incandescent light bulbs, X-ray production, missiles, heaters, and even more random stuff.
This is a negative effect of mining tungsten
It can run into the water streams and make the water toxic for animals, causing anorexia, colic, in-coordination of movement, trembling, dyspnea and weight loss.
