More info

Our Tantalum tungsten alloy, available in grades Ta2.5W and Ta10W, is especially well-suited for heat exchangers and heating components used in the construction of chemical instruments. Tantalum Tungsten Alloy stands out for its commendable mechanical properties and remarkable corrosion resistance. 

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.
