Understanding refractory metals
Refractory metals share the common properties of melting points over 2200°C [3992°F], high corrosion resistance and maintain superior mechanical strength in high-temperature applications. Among the refractory metals, we offer Tantalum and Niobium. You can click the links below to learn more.
- Tantalum is available in grades 5200, 5400, and 5400-SI-Doped in bar or wire form with options for coil form, cut-to-length, or on a spool end product, with a high-quality surface finish.
- Niobium is available in 4200 - Type 1 reactor grade in wire form with options for coil form, cut-to-length, or on a spool end product.
Also, we offer a variety of tungsten and molybdenum high-performance alloys.
