As a pseudo-alloy, Mo-Cu alloy is composed of molybdenum and copper that not melt in solid solution, and integrated each others. It is characterized by high thermal conductivity, low and adjustable coefficient of thermal expansion, non-magnetic, low gas content, good vacuum performance, good machining ability and outstanding properties in high temperature. It is widely used in machinery, electric power, electronics, electric vehicle，metallurgy and other industries
Typical applications are as below:
• Power amplifier heat spreader material.
• Radio base station in telecommunications
• Heat spreader on electronic devices
• Electrode used in electric resistance welding electrodes
• Electrode used in electric resistance welding electrodes
• Electronic packaging materials and heat sink materials
• IGBT modules for electric vehicle motors (EV/HEV)
• Lead frame with high performance
• Thermal control plates and heat spreader
