Brief Introduction of molybdenum copper material at home and abroad

The 1960s, the former Soviet scholars have conducted research molybdenum copper material as given certain expansion coefficient of expansion alloys to study the effects of copper content of the alloy material expansion coefficient. 1970s, domestic molybdenum had a high thermal conductivity material fixed copper expanded tube power semiconductor substrate conducted research, it is higher than the thermal conductivity of the pure aluminum and molybdenum, and less than the coefficient of expansion and oxygen-free copper, the coefficient of expansion and ceramic materials such as silicon good match. 1980s, by adding a small amount of nickel or other elements molybdenum copper, used with non-magnetic ceramic sealing material sealing metal chords vibrating pressure sensor temperature compensation from non-magnetic material given expansion. However, due to various constraints, and these efforts have not been very good promotion, application objects relatively simple stenosis, the amount is very small. The late 1980s, foreign material as the molybdenum-copper tubes and vacuum switch electrical switch electrical contacts for the production and application, while developing a large scale integrated circuits and other microelectronic devices, heat sink material. After 90 years, the country through the introduction of technology, but also the production of molybdenum-copper contacts using vacuum switch tube, and molybdenum-copper alloy heat sink materials used in research.
