Tantalum alloy formed by adding certain amount of tungsten elements to tantalum base. Ta-W binary series alloy of tantalum and tungsten is an infinite solid solution. The strength of the alloy increases with the increase of tungsten content, but the plasticity of the recrystallized alloy decreases significantly with the increase of 12% ~ 14%(atomic fraction) (see figure). The tantalum tungsten alloys manufactured in the United States are Ta-2.5W, Ta-7.5W and Ta-10W. These tantalum alloys maintain the low temperature plasticity of pure tantalum and have high strength and oxidation resistance. Since 1960s, tantalum tungsten alloy has been used in aerospace industry and chemical industry as high-temperature structural material and corrosion resistant material.
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.
