Tantalum Tungsten Rod
Product Tantalum Tungsten Rod / Bar (Ta-W Rod/ Ta-W Bar)
Part Number TRM-TA009
Standard ASTM B365 UNS R05252/ UNS R05255
Assay Ta97.5W2.5 or Ta90W10
Density 16.9 g/cm3

Tantalum tungsten alloy (Ta-W alloy) is typically tantalum 2.5% Tungsten and tantalum 10% Tungsten of high density 16.90 g/cm3. It has good high-temperature mechanical properties, high density, high strength, good toughness and strong stiffness, and the working temperature can be up to 1500°C. In addition, tantalum tungsten alloy rod has excellent corrosion resistance. We can offer a wide variety of diameters.

Application: Tantalum tungsten alloy rod is used for chemical process equipment including heating and cooling coils, heat exchange, condensers, reaction vessels, leaf springs and bellows.

Thermostability 93%
Machinability 81%
Corrosion Resistance 92%
