Tantalum Metal Powder
Oasis Materials Technology provides high quality Tantalum metal powder at competitive price.
Tantalum 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. Tantalum is also an refractory metals.
