Molybdenum Copper Alloy

Molybdenum Copper Alloy are composite rolled by fusion infiltration of molybdenum-copper alloys and molybdenum-copper sandwich structure bimetallic and mechanically processed into the final product, featuring an adjustable thermal expansion coefficient and thermal conductivity. It offers lower density but a higher thermal expansion coefficient than tungsten-copper (WCu) alloy. Molybdenum Copper Alloys offer good strength and plasticity at room and intermediate temperatures. At high temperatures, copper melts and evaporates, absorbing heat. This property makes the alloy ideal for high-temperature applications like rocket nozzle liners and electrical contacts in arc conditions. HM provides high-precision Mo-Cu alloy products with various specifications, all crafted to ensure exceptional quality and customer satisfaction.
