Aluminum BAlSi-2 CLAD-H14 vs BAlSi-2-H14
Aluminum · BAlSi-2 temper comparison
BAlSi-2 CLAD-H14 and BAlSi-2-H14 are two conditions of the same aluminum grade, BAlSi-2: CLAD-H14 (4343-clad brazing sheet, half-hard composite) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. BAlSi-2-H14 is the stronger of the two: yield strength 145 MPa (21 ksi) against 130 MPa (18.9 ksi) for BAlSi-2 CLAD-H14, about 12% more; tensile strength follows at 165 MPa (23.9 ksi) vs 150 MPa (21.8 ksi). In exchange, BAlSi-2 CLAD-H14 is the more ductile: elongation 8% versus 5% for BAlSi-2-H14, and BAlSi-2-H14 is harder (52 HB vs 40 HB). BAlSi-2 CLAD-H14 runs hotter in service (150°C vs 120°C continuous). On the shop floor, BAlSi-2-H14 machines more easily (50 vs 40 out of 100) and BAlSi-2 CLAD-H14 welds better (good vs fair).
BAlSi-2 CLAD-H14Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
BAlSi-2-H14Choose it when strength drives the design, or when the part is machined in volume.
BAlSi-2 CLAD-H14 vs BAlSi-2-H14: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all aluminum 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.

BAlSi-2 CLAD-H14 vs BAlSi-2-H14 — frequently asked
Is BAlSi-2-H14 stronger than BAlSi-2 CLAD-H14?
Yes. BAlSi-2-H14 has a typical yield strength of 145 MPa (21 ksi) against 130 MPa (18.9 ksi) for BAlSi-2 CLAD-H14 — about 12% more. Tensile strength is 165 MPa (23.9 ksi) vs 150 MPa (21.8 ksi).
Which condition does FabDigit quote by default, CLAD-H14 or H14?
AS-BRAZED is the default BAlSi-2 condition in the FabDigit quote flow (neither CLAD-H14 nor H14). 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, BAlSi-2 CLAD-H14 or BAlSi-2-H14?
BAlSi-2-H14, by a small margin. Both rate fair for machinability — 50/100 against 40/100 for BAlSi-2 CLAD-H14; for welding the order is BAlSi-2 CLAD-H14 first (good, 55/100) then BAlSi-2-H14 (fair, 45/100).
