Refractory Metals & Powder Metallurgy

Due to their high melting points and hardness, the refractory metals are most often processed in powder form and never fabricated by casting.

Metal powders are manufactured to specific sizes and forms, then blended to create the right mixture of properties, before being compacted and sintered.

Sintering involves heating the metal powder (within a mold) for a long period of time. Under heat, the powder particles begin to bond, forming a solid piece.

Sintering can bond metals at temperatures lower than their melting point, a significant advantage when working with the refractory metals.
 

Applications

Refractory metal-based alloys and carbides are used in virtually all major industries, including electronics, aerospace, automotive, chemicals, mining, nuclear technology, metal processing, and prosthetics.
