Copper Alloy C87500-M01 vs C87500-M06

Copper Alloy · C87500 temper comparison

C87500-M01 and C87500-M06 are two conditions of the same copper alloy grade, C87500: M01 (as sand cast) versus M06 (as investment cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 225 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as sand cast versus as investment cast). C87500-M06 is the more ductile: elongation 21% versus 18% for C87500-M01, and C87500-M06 is harder (115 HB vs 100 HB).
