How to Order MHC Alloy

MHC alloy is  also called MHC molybdenum base alloy, molybdenum alloy MHC, molybdenum MHC, molybdenum high temperature MHC, molybdenum-hafnium-carbide.

Molybdenum hafnium carbide (MHC) alloy is a particle-reinforced molybdenum alloy which contains hafnium and carbon. The carbon is uniformly distributed along the alloys structure giving it excellent heat and creep resistant properties at elevated temperatures of 1550°C (2822°F). This alloy is able to function under extreme mechanical and thermal loads.

This alloy is manufactured by the process of powder metallurgy. Some of the advantages that this alloy offers are dimensional stability, optimum non-deformability, high thermal stability, no cold brittleness, good hot ductility and very high crystallization temperatures.

This datasheet will look into the chemical composition, properties and applications of MHC alloy.
