Product Code : EM-Ta-5N-Cu
Tantalum has a melting point of 3,017°C, a density of 16.6 g/cc, and vapor pressure of 10-4 Torr at 2,590°C. It is a dark blue-gray metal that is very heavy, ductile and hard and has high corrosion resistance. Tantalum is especially resistant to chemicals at temperatures below 150 °C and can only be dissolved with hydrofluoric acid. It is mainly used to make surgical implants due to its non-toxic nature. It is also used as a capacitor for electronics and may be alloyed with other metals to add strength and durability.
