Specifications Reactive Refractory Alloys

Refractory metals are a group of materails that includes niobium , tantalum, molybdenum, tungsten, and rhenium. Tthis group of metals are know for thier high melting temperatures, which range from 2468 to 3410°C (4474 to 6170°F). The metals and their alloys find specialized applications in the electronics, aerospace, nuclear, and chemical process industries.
