Copper Alloy CC752S vs CC753S

Copper Alloy · grade comparison

Copper Alloy CC752S and CC753S are both copper alloy grades. CC753S is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 110 MPa (16 ksi) for CC752S, about 36% more; tensile strength follows at 320 MPa (46.4 ksi) vs 280 MPa (40.6 ksi). CC753S is the more ductile: elongation 18% versus 15% for CC752S, and CC753S is harder (80 HB vs 75 HB). CC752S conducts heat better (115 W/m·K vs 100 W/m·K). On the shop floor, CC753S sits in a lower cost tier (premium, $$$) than CC752S (high, $$$$).

CC753SChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

CC752S vs CC753S — frequently asked

Is CC753S stronger than CC752S?

Yes. CC753S has a typical yield strength of 150 MPa (21.8 ksi) against 110 MPa (16 ksi) for CC752S — about 36% more. Tensile strength is 320 MPa (46.4 ksi) vs 280 MPa (40.6 ksi).

Which is cheaper, CC752S or CC753S?

CC753S is the lower-cost material: it sits in the premium tier ($$$) while CC752S is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

When should I choose CC752S over CC753S?

Pick CC753S when strength drives the design, or when the part is bent, formed or impact-loaded.
