Copper Alloy BrAZhMts10-3-1.5-ANN vs BrAZhMts10-3-1.5 SAND
Copper Alloy · BrAZhMts10-3-1.5 temper comparison
BrAZhMts10-3-1.5-ANN and BrAZhMts10-3-1.5 SAND are two conditions of the same copper alloy grade, BrAZhMts10-3-1.5: ANN (annealed) versus SAND (sand cast). The chemistry is identical, so every difference below comes from the condition. BrAZhMts10-3-1.5-ANN is the stronger of the two: yield strength 240 MPa (34.8 ksi) against 200 MPa (29 ksi) for BrAZhMts10-3-1.5 SAND, about 20% more; tensile strength follows at 560 MPa (81.2 ksi) vs 490 MPa (71.1 ksi). BrAZhMts10-3-1.5-ANN is the more ductile: elongation 20% versus 12% for BrAZhMts10-3-1.5 SAND, and BrAZhMts10-3-1.5-ANN is harder (140 HB vs 120 HB).

BrAZhMts10-3-1.5-ANN vs BrAZhMts10-3-1.5 SAND: 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 SAND — frequently asked
Is BrAZhMts10-3-1.5-ANN stronger than BrAZhMts10-3-1.5 SAND?
Yes. BrAZhMts10-3-1.5-ANN has a typical yield strength of 240 MPa (34.8 ksi) against 200 MPa (29 ksi) for BrAZhMts10-3-1.5 SAND — about 20% more. Tensile strength is 560 MPa (81.2 ksi) vs 490 MPa (71.1 ksi).
Which condition does FabDigit quote by default, ANN or SAND?
SAND is the default BrAZhMts10-3-1.5 condition in the FabDigit quote flow. 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 SAND?
BrAZhMts10-3-1.5 SAND, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for BrAZhMts10-3-1.5-ANN; for welding the order is BrAZhMts10-3-1.5-ANN first (very good, 75/100) then BrAZhMts10-3-1.5 SAND (very good, 70/100).
