Copper Motor Rotor

The melting temperatures of copper alloys C10100 and C11000 are listed in Table 9.2.1. The lower solidus temperature for C11000 is due to the presence of 0.04 wt. % oxygen.

Parameter	Alloy
Parameter	C10100	C11000
Liquidus temperature	1083^oC (1981^oF)	1083^oC (1981^oF)
Solidus temperature	1083^oC (1981^oF)	1065^oC (1949^oF)

Table 9.2.1: Solidus and Liquidus temperatures for copper alloys C10100 and C11000

A furnace for copper rotor die-casting needs to be capable of heating the liquid copper to temperatures as high as 1250 to 1375oC (2282 to 2507oF). This represents a superheat of 167 to 292oC (300 to 526oF).
