WebPowdered metal (PM) components are excellent, cost-effective alternatives to machining metal components from wrought steel, but one difference between wrought steel and powder metal is density. The typical density range for the PM process is 85% to 93% (6.6 g/cm 3 to 7.3 g/cm 3) in structural applications, 75% to 87% (5.8 g/cm 3 to 6.8 g/cm 3) in … WebMechanical Properties of Copper and Copper Alloys at Low Temperatures. Publist#: 144/8. Copper alloys become stronger and more ductile as temperature goes down. They also retain excellent impact resistance to 20 K. These general characteristics have been revealed in tests on 15 copper alloys, including brasses, bronzes and commercially pure ...
