Copper Alloy C18980-AW vs C18980-O60

Copper Alloy · C18980 temper comparison

C18980-AW and C18980-O60 are two conditions of the same copper alloy grade, C18980: AW (as-welded deposit) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C18980-AW is the stronger of the two: yield strength 80 MPa (11.6 ksi) against 70 MPa (10.2 ksi) for C18980-O60, about 14% more. In exchange, C18980-O60 is the more ductile: elongation 42% versus 32% for C18980-AW, and C18980-AW is harder (65 HB vs 48 HB).

C18980-AWChoose it when strength drives the design.

C18980-O60Choose it when the part is bent, formed or impact-loaded.
