Aluminum BAlSi-2 CLAD-O vs BAlSi-2-H14

Aluminum · BAlSi-2 temper comparison

BAlSi-2 CLAD-O and BAlSi-2-H14 are two conditions of the same aluminum grade, BAlSi-2: CLAD-O (4343 cladding on 3003 brazing sheet, annealed 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 48 MPa (6.96 ksi) for BAlSi-2 CLAD-O, about 3.0 times as much; tensile strength follows at 165 MPa (23.9 ksi) vs 115 MPa (16.7 ksi). In exchange, BAlSi-2 CLAD-O is the more ductile: elongation 25% versus 5% for BAlSi-2-H14, and BAlSi-2-H14 is harder (52 HB vs 32 HB). BAlSi-2 CLAD-O runs hotter in service (150°C vs 120°C continuous) and BAlSi-2 CLAD-O conducts electricity better (47 % IACS vs 41 % IACS). On the shop floor, BAlSi-2-H14 machines more easily (fair vs poor) and BAlSi-2 CLAD-O welds better (good vs fair).

BAlSi-2 CLAD-OChoose 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-O vs BAlSi-2-H14 — frequently asked

Is BAlSi-2-H14 stronger than BAlSi-2 CLAD-O?

Yes. BAlSi-2-H14 has a typical yield strength of 145 MPa (21 ksi) against 48 MPa (6.96 ksi) for BAlSi-2 CLAD-O — about 3.0 times as much. Tensile strength is 165 MPa (23.9 ksi) vs 115 MPa (16.7 ksi).

Which condition does FabDigit quote by default, CLAD-O or H14?

AS-BRAZED is the default BAlSi-2 condition in the FabDigit quote flow (neither CLAD-O 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-O or BAlSi-2-H14?

BAlSi-2-H14. Its machinability rates fair (50/100) against poor (30/100) for BAlSi-2 CLAD-O; for welding the order is BAlSi-2 CLAD-O first (good, 55/100) then BAlSi-2-H14 (fair, 45/100).
