Copper Alloy C75200 vs C76200
Copper Alloy · grade comparison
Copper Alloy C75200 and C76200 are both copper alloy grades. Both yield at about 427 MPa — strength does not separate them. C76200 is the more ductile: elongation 10% versus 6% for C75200. C75200 runs hotter in service (200°C vs 175°C continuous) and C75200 conducts heat better (33 W/m·K vs 29 W/m·K).
C75200Choose it when the part sees heat.
C76200Choose it when the part is bent, formed or impact-loaded.
C75200 vs C76200: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all copper alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

C75200 vs C76200 — frequently asked
What is the difference between C75200 and C76200?
Copper Alloy C75200 and C76200 are both copper alloy grades. Both yield at about 427 MPa — strength does not separate them. C76200 is the more ductile: elongation 10% versus 6% for C75200.
Which is cheaper, C75200 or C76200?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, C75200 or C76200?
C76200, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for C75200; for welding the order is C76200 first (fair, 50/100) then C75200 (fair, 45/100).
