Copper Alloy BrAZhMts10-3-1.5-ANN vs BrAZhMts10-3-1.5-HT
Copper Alloy · BrAZhMts10-3-1.5 temper comparison
BrAZhMts10-3-1.5-ANN and BrAZhMts10-3-1.5-HT are two conditions of the same copper alloy grade, BrAZhMts10-3-1.5: ANN (annealed) versus HT (heat treated). The chemistry is identical, so every difference below comes from the condition. BrAZhMts10-3-1.5-HT is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 240 MPa (34.8 ksi) for BrAZhMts10-3-1.5-ANN, about 33% more; tensile strength follows at 655 MPa (95 ksi) vs 560 MPa (81.2 ksi). In exchange, BrAZhMts10-3-1.5-ANN is the more ductile: elongation 20% versus 8% for BrAZhMts10-3-1.5-HT, and BrAZhMts10-3-1.5-HT is harder (195 HB vs 140 HB). On the shop floor, BrAZhMts10-3-1.5-ANN welds better (very good vs good).

BrAZhMts10-3-1.5-ANN vs BrAZhMts10-3-1.5-HT: 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.

BrAZhMts10-3-1.5-ANN vs BrAZhMts10-3-1.5-HT — frequently asked
Is BrAZhMts10-3-1.5-HT stronger than BrAZhMts10-3-1.5-ANN?
Yes. BrAZhMts10-3-1.5-HT has a typical yield strength of 320 MPa (46.4 ksi) against 240 MPa (34.8 ksi) for BrAZhMts10-3-1.5-ANN — about 33% more. Tensile strength is 655 MPa (95 ksi) vs 560 MPa (81.2 ksi).
Which condition does FabDigit quote by default, ANN or HT?
SAND is the default BrAZhMts10-3-1.5 condition in the FabDigit quote flow (neither ANN nor HT). 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, BrAZhMts10-3-1.5-ANN or BrAZhMts10-3-1.5-HT?
BrAZhMts10-3-1.5-ANN, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for BrAZhMts10-3-1.5-HT; for welding the order is BrAZhMts10-3-1.5-ANN first (very good, 75/100) then BrAZhMts10-3-1.5-HT (good, 55/100).
