As the raw material of C103 alloy, niobium - tantalum - tungsten alloy bar has strict requirements on Ta, W and gas impurities C and O. The process of producing nb-ta-w alloy bar by powder metallurgy is studied in this paper. The method of uniform distribution of Ta and W was found out, and a reasonable process scheme was put forward.
The tantalum tungsten alloy has higher strength than pure tantalum and similar corrosion resistance to pure tantalum. Tantalum tungsten alloy springs are mainly used in aviation industry, chlorine-alkali industry, chlorination industry and other fields.
Tantalum-tungsten alloy spring is one of the most difficult springs in the world. As one of the most important producers of tantalum-tungsten alloy springs in China, huachuang ruixin has the most mature production capacity of tantalum-tungsten alloy springs in China. According to customer requirements, the use of domestic or imported tantalum tungsten alloy wire, processing and production of various specifications of tantalum tungsten alloy springs.
