Product Code : AL-TaW-Ta90W10-SP
Tantalum Tungsten Alloy excels due to its sensible mechanical properties and glorious corrosion resistance. 97.5% Tantalum 2.5% Tungsten (Ta-2.5W) alloy is widely applied in chemical industry. The corrosion resistance of tantalum-tungsten alloy is better than pure tantalum. Ta2.5W can be used as the corrosion protection component of heat exchange equipment in chemical industry, pipe and lining, anti-corrosion of instrument and instrument, crucible of rare earth smelting, etc. The addition of 2.5 % to 10 % tungsten to tantalum increases the strength of the material, and the alloying of tungsten to tantalum forms an alternative continuous solid solution that still maintains the body-centered cubic crystal structure of tantalum, while also maintaining the easy processing properties of tantalum. Tantalum alloys that are currently widely used in industry include Ta-2.5W, TaW10, TaW12, and Ta-7.5W.
