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.
