Tantalum Foil & Tantalum Strip Description

Tantalum foil & tantalum strip is made of dark blue-gray tantalum metal that is very heavy, ductile, and hard, and has high corrosion resistance. Tantalum foil is especially resistant to chemicals at temperatures below 150 °C and can only be dissolved with hydrofluoric acid. Tantalum strip has the fourth-highest melting point of all metals and is able to form extremely thin and protective oxide layers for high-quality capacitors, making it an excellent material for foil.
