Product Description:
Tantalum-tungsten alloy is a tantalum alloy formed based on tantalum and adding a certain amount of tungsten element. The Ta-W binary system alloy composed of tantalum and tungsten is an infinite solid solution. As the tungsten content increases, the strength of the alloy increases, but When it exceeds 12%~14% (atomic fraction), the shaping of the recrystallized alloy will be significantly reduced. Tantalum-tungsten alloys include Ta-2.5W and Ta-10W. These tantalum alloys maintain the low-temperature plasticity of pure tantalum and have relatively high With high strength and oxidation resistance, it is an indispensable and important material in aerospace, chemistry, nuclear industry, high temperature technology and other fields.
