Copper Alloy C94800-M02 vs C94800-TF00
Copper Alloy · C94800 temper comparison
C94800-M02 and C94800-TF00 are two conditions of the same copper alloy grade, C94800: M02 (as centrifugally cast) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C94800-TF00 is the stronger of the two: yield strength 275 MPa (39.9 ksi) against 170 MPa (24.7 ksi) for C94800-M02, about 62% more; tensile strength follows at 415 MPa (60.2 ksi) vs 330 MPa (47.9 ksi). In exchange, C94800-M02 is the more ductile: elongation 30% versus 10% for C94800-TF00, and C94800-TF00 is harder (140 HB vs 85 HB). C94800-M02 runs hotter in service (230°C vs 200°C continuous) and C94800-TF00 conducts heat better (52 W/m·K vs 46 W/m·K). On the shop floor, C94800-M02 machines more easily (very good vs good).
C94800-M02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C94800-TF00Choose it when strength drives the design.
C94800-M02 vs C94800-TF00: 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.

C94800-M02 vs C94800-TF00 — frequently asked
Is C94800-TF00 stronger than C94800-M02?
Yes. C94800-TF00 has a typical yield strength of 275 MPa (39.9 ksi) against 170 MPa (24.7 ksi) for C94800-M02 — about 62% more. Tensile strength is 415 MPa (60.2 ksi) vs 330 MPa (47.9 ksi).
Which condition does FabDigit quote by default, M02 or TF00?
M01 is the default C94800 condition in the FabDigit quote flow (neither M02 nor TF00). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, C94800-M02 or C94800-TF00?
C94800-M02. Its machinability rates very good (80/100) against good (60/100) for C94800-TF00; for welding the order is C94800-M02 first (poor, 30/100) then C94800-TF00 (poor, 25/100).
