Tantalum Tungsten Alloy Wire Description
Tantalum tungsten 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 1600℃. In addition, tantalum tungsten alloy wire has excellent corrosion resistance especially in acids.
SSC specializes in providing high purity & uniform shaped tantalum wire with the highest possible density. We also supply tantalum tungsten alloy and tantalum niobium alloy wire.
