Tantalum Foil and Strip
Ta
Purities available: 99.95%, 99.99%
Tantalum foil and Tantalum strip is made of the 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.
Applications:
Applications for Tantalum Foil and Strip include; laboratory equipment, as a substitute for platinum, in manufacturing of super alloys and electron-beam melting, metallurgical, machinery processing, glass, and ceramic industries.
