It is a ductile metal with very high thermal and electrical conductivity.
Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color.
It is used as a conductor of heat and electricity, a building material
, and a constituent of various metal alloys.
Copper parts will have density between 5.5 to 6.8 g/cc after sintering.
The hardness is around 50 to 70 HRB.
