UNS C87800 copper alloy has a copper content of not less than 80%. The following table shows the mechanical properties of UNS C87800 die cast alloy as a function of heat treatment.

Six different sizes and types of rotors were die cast using pure, highconductivity copper. Tests showed a 1.2 to 1.7 % improvement in efficiency. When it comes to energy efficiency, every little bit ...

Aluminum is good, but copper is better -- at least when you're talking about die-cast rotors in three-phase induction motors. Siemens Energy & Automation, based in Alpharetta, Ga., offers a new line ...

• Rotors made from copper conduct electrical current better than aluminum, thus run cooler with more efficiency. • The process of die casting copper has become economical thanks to recent advances in ...
