Copper Density and Hardness

In general, the hardness and density of both Molybdenum copper and tungsten copper decrease as their copper content increases. Tungsten copper with a copper volume fraction same as molybdenum copper has a higher density and hardness. Their electrical conductivities and thermal expansion rates go up with the increase of their copper percentage.
