Copper Alloy BrAZhMts10-3-1.5-ANN vs BrAZhMts10-3-1.5 CHILL

Copper Alloy · BrAZhMts10-3-1.5 temper comparison

BrAZhMts10-3-1.5-ANN and BrAZhMts10-3-1.5 CHILL are two conditions of the same copper alloy grade, BrAZhMts10-3-1.5: ANN (annealed) versus CHILL (chill / permanent-mould cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 240 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (annealed versus chill / permanent-mould cast). BrAZhMts10-3-1.5-ANN is the more ductile: elongation 20% versus 14% for BrAZhMts10-3-1.5 CHILL, and BrAZhMts10-3-1.5-ANN is harder (140 HB vs 130 HB).
