Mo80Cu20 Molybdenum Copper Alloy Sheet 0.5~20mm Thick MoCu Sheet Heat Sink Material
Mo80Cu20 Molybdenum Copper Alloy Sheet
1. Description of Mo80Cu20 Molybdenum Copper Alloy Sheet:
Molybdenum-copper alloy sheet is a composite made of molybdenum and copper. Similar to tungsten-copper, the thermal expansion coefficient of molybdenum-copper alloy can also be tailored by adjusting the structure. Ideal for aerospace applications.
Moreover, the molybdenum-copper alloy sheet has the characteristics of both molybdenum and copper, and has the characteristics of high thermal conductivity, low adjustable thermal expansion coefficient, non-magnetic, low gas content, good vacuum performance, good machinability and special high temperature performance. . Widely used in machinery, electricity, electronics, electric vehicles, metallurgy and other industries.
