Tantalum And Tantalum Alloy Products

Source: Tantalum and tantalum alloy products

Tantalum and Tantalum Alloys (such as Ta-2.5W, Ta-10W, Ta-40Nb, etc.) pipe with a high melting point, corrosion resistance, good cold working properties, etc

Product application

Pipe is widely used in chemical industry, the field of high temperature technology and atomic to industry, mainly for manufacturing process of chemical reaction vessel and heat exchanger, pipe, a condenser, a bayonet heaters, the spiral coil, a U-shaped tube, thermocouple and its protection tube, liquid metal containers and pipelines. (executive standard: ASTMB52198).

Bar is widely used in aviation and aerospace industry, high technology, atomic energy industry and chemical industry, mainly used to produce a supersonic aircraft, rockets, spacecraft combustion chamber components, high temperature resistance furnace parts, resistance to nitric acid, sulfuric acid, hydrochloric acid corrosion of parts. (executive standard: ASTMB36598).
