Product Code : AL-MHC-CU-CU
MHC alloy is the upgraded TZM alloy product, with superior performance and strength compared to TZM alloy.
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.
ATT is a professional supplier of high-purity Molybdenum Hafnium Carbide (MHC) Alloy. We also produce disc, granules, ingot, pellets, pieces, powder , rod, wire, sputtering target and in numerous other forms and custom shapes. Other shapes are available by request.
Please contact us if you need customized services. We will contact you with the price and availability in 24 hours.
