Molybdenum Copper & Tungsten Copper Comparison

Molybdenum Copper & Tungsten Copper Comparison

Molybdenum higher than the melting point of tungsten, molybdenum density than large, so tungsten-copper alloy is more suitable for higher temperatures, can be applied as a high-density material. The relatively low density of molybdenum due, so using molybdenum-copper alloy can reduce part weight, which for the aerospace and instrumentation requirements as lightweight when favorable.
