| Product | Tantalum Tungsten Tubing (TaW Tube/Pipe) |
| Part Number | TRM-TA004 |
| Standard | ASTM B521 UNS R05252/ UNS R05255 |
| Assay | Ta97.5W2.5 or Ta90W10 |
| Type | Seamless or Welded |
| 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 tubing has excellent corrosion resistance especially in acids. We can offer a wide variety of diameters and wall thicknesses. Our tantalum material is from Non-Conflict Resource.
Application: Tantalum response vessel, tantalum heat exchangers pipes, protective tubes and etc.
