Molybdenum-copper alloy

Molybdenum-copper alloy is an alloy material made of two metal elements, molybdenum and copper, through a fine process. This alloy combines the high conductivity of copper with the high strength and high melting point of molybdenum, so it has the advantages of high strength, high specific gravity, high temperature resistance, arc ablation resistance, good conductive electrothermal performance, and good processing performance.

Product Introduction

The preparation of molybdenum copper alloy mainly adopts the melting and leaching method, through the mixing of high quality molybdenum powder and oxygen-free copper powder, the application of isostatic pressure molding (high temperature sintering-copper infiltration) process, to produce fine tissue, excellent performance of the alloy material. The alloy has good arc breaking performance, good electrical conductivity, good thermal conductivity, and small thermal expansion, so it is widely used in many fields.

In the field of electronic devices, molybdenum-copper alloys are commonly used in the manufacture of microwave connectors, relay contacts, integrated circuit substrates, etc., taking advantage of their excellent electrical conductivity and thermal conductivity. In the field of welding materials, molybdenum-copper alloys are excellent materials for electrodes, electrical contacts and other welding tools because of their high-temperature corrosion resistance and high thermal conductivity. In addition, molybdenum-copper alloys are also used in the manufacture of infrared detectors, petrochemical equipment, engine combustion chambers and nozzle components in the aerospace field, and parts of precision instruments.
