Molybdenum Hafnium Carbon Alloy Description

Molybdenum hafnium carbide (MHC) alloy is a particle-reinforced molybdenum alloy that contains hafnium and carbon. Molybdenum has excellent creep resistance, low resistivity, high corrosion resistance, high thermal conductivity, and low thermal expansion. Comparing to pure molybdenum, Molybdenum Hafnium Carbon Alloy has higher heat resistance, better creep resistance, and higher recrystallization temperature.
