Pure tungsten is a steel-gray to tin-white metal. Tungsten has the highest melting point and lowest vapour pressure of all metals, and at temperatures over 1650°C has the highest tensile strength. The metal oxidises in air and must be protected at elevated temperatures. It has excellent corrosion resistance and is attacked only slightly by most mineral acids.
Tungsten is available in many forms including foil, powder, rod, nanosized activated powder, sheet, disc, plate, wire and etc.; tungsten and its alloys are used extensively for filaments for electric lamps, electron and television tubes, and for metal evaporation work, windings and heating elements for electrical furnaces; high-speed tool steels...
