Copper Alloy CuCrZr
Copper Alloy CuCrZr is a high strength copper alloy — high-strength conductive copper. Typical values: 380 MPa yield, 8.89 g/cm³, rated to 350 °C. Available for 3D printing at FabDigit.
Properties
Typical room-temperature values in the Aged (precipitation aged) condition. Metric first, imperial in gray. The bars show where CuCrZr sits against the other 36 copper alloy grades in the catalog.

Property data is compiled from published supplier and standards handbooks and normalised for comparison; hardness values on non-Brinell scales are converted approximately for charting only. Manufacturability limits are FabDigit quote-engine defaults and may be relaxed by engineering review. Nothing on this page is a certification — request mill certs, CoC or material test reports with your order.
