- tungsten, molybdenum, tantalum, niobium and rhenium,ods-copper,
cemented carbide.
Products
Tungsten & Tungsten Alloy
Material Property:
Tantalum and tantalum alloy (e.g., Ta, Ta - 10-2.5 - W - 40 W, Ta Nb, etc.) pipes have high melting point, good corrosion resistance and good performance in cold machining.
Application:
Pipes are widely adopted in chemical industry, high technology and atomic energy industry, mainly used in reaction container, pipe, condenser, bayonet heater, spiral coil, U tube, thermocouple protection tube, the liquid metal container and its pipes, etc, in chemical process.(executive standard: ASTMB521-98).Rods are widely used in aviation and aerospace industry, high –temperature technology, atomic energy industry and chemical industry, mainly used to make supersonic aircraft, rocket, the spacecraft components of the combustion chamber, high –temperature-resistance furnace, and some spare parts with corrosion resistance for resisting nitric acid, sulfuric acid,and hydrochloric acid etc.(executive standard: ASTMB365-98).
