Copper Alloy CC332G-GM vs CC332G-GS

Copper Alloy · CC332G temper comparison

CC332G-GM and CC332G-GS are two conditions of the same copper alloy grade, CC332G: GM (permanent (chill) mould cast) versus GS (sand cast). The chemistry is identical, so every difference below comes from the condition. CC332G-GM is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 250 MPa (36.3 ksi) for CC332G-GS, about 16% more; tensile strength follows at 650 MPa (94.3 ksi) vs 570 MPa (82.7 ksi). CC332G-GM is harder — 150 HB against 120 HB for CC332G-GS — which matters for wear surfaces and threads.

CC332G-GMChoose it when strength drives the design, or when surface hardness matters.
