High purity new products best price tantalum tungsten alloy tube ,Tantalum Tube/Pipe/Tubing

Tantalum (Ta) 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 hydrofluouric acid. It 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 tubes.
Applications:• Used for the manufacturing of reaction vessels.

• Used for heat exchanger pipes, condensers, bayonet heaters, helical coils, thermocouple and protective tubes, etc.
