Working with 5154A-H112
Is 5154A easy to machine?
Gummy in soft tempers — use sharp polished high-rake carbide, high speed, generous lubricant; chip control improves markedly in H1x/H3x tempers.
Can 5154A be welded?
Excellent with GMAW/GTAW using 5356 or 5183 filler; do not use 4043 (brittle Mg2Si), and expect the HAZ to drop back to near-O strength.
Can 5154A be formed, bent or molded?
Very good cold formability in O/H111; for H22–H38 increase bend radii and bend across the rolling direction; hot forming above ~200 °C risks sensitization if followed by service warm.
What surface finishes work on 5154A?
Anodizes clear to light grey, takes conversion coating and paint well; avoid mercury-bearing or strongly alkaline cleaners and keep service below ~65 °C to prevent grain-boundary β-phase precipitation.

5154A-H112 — frequently asked
What is 5154A-H112 used for?
5154A-H112 is typically used for pressure vessels, structural sheet, shipbuilding and welded assemblies. In short: EN counterpart to 5154; weldable marine-grade sheet; 65 °C service ceiling.
What is the yield strength of 5154A-H112?
5154A-H112 has a typical yield strength of 120 MPa (17.4 ksi) and a tensile strength of 240 MPa (34.8 ksi) — weaker than 77% of aluminum grades. Strength varies by condition: see the 17 listed tempers.
Is 5154A-H112 easy to machine?
Not especially — machinability is rated fair (40/100, worse than 81% of aluminum grades). Gummy in soft tempers — use sharp polished high-rake carbide, high speed, generous lubricant; chip control improves markedly in H1x/H3x tempers.
Can 5154A-H112 be welded?
Yes — weldability is rated excellent (91/100). Excellent with GMAW/GTAW using 5356 or 5183 filler; do not use 4043 (brittle Mg2Si), and expect the HAZ to drop back to near-O strength.
What surface finishes work on 5154A-H112?
Anodizes clear to light grey, takes conversion coating and paint well; avoid mercury-bearing or strongly alkaline cleaners and keep service below ~65 °C to prevent grain-boundary β-phase precipitation.
Can 5154A-H112 be formed, bent or molded?
Very good cold formability in O/H111; for H22–H38 increase bend radii and bend across the rolling direction; hot forming above ~200 °C risks sensitization if followed by service warm.
What is the maximum service temperature of 5154A-H112?
5154A-H112 is rated for continuous use to about 90°C (194 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 5154A-H22 and 5154A-H19?
H22 is the default condition — most commonly stocked EN sheet/plate condition: balanced strength, forming ability and stable properties for marine and tank work. H19: thin strip/foil condition for the highest as-rolled strength; essentially non-formable. Yield strength is 195 MPa in H22 versus 305 MPa in H19.
