Working with 5005A-H24
Is 5005A easy to machine?
Soft and gummy — use sharp polished high-rake carbide, high surface speed and generous lubrication to avoid built-up edge; chip breaking is poor in O/H1x tempers.
Can 5005A be welded?
Excellent by GTAW/GMAW and resistance welding with 5356 or 5183 filler; HAZ softens back toward O-temper so design joints at annealed strength.
Can 5005A be formed, bent or molded?
Very good cold formability — deep draw and spin in O/H22/H24; use larger bend radii and cross-grain bending for H16/H18/H36/H38.
What surface finishes work on 5005A?
Purpose-built for anodizing: clear, bright and coloured films come out uniform; also takes chemical conversion coating, powder coat and PVDF paint; mechanical polishing gives good specular finish.

5005A-H24 — frequently asked
What is 5005A-H24 used for?
5005A-H24 is typically used for anodized architectural panels, decorative trim and light-gauge sheet. In short: anodizing-grade 5000-series sheet; very good cold formability; low strength, high weldability.
What is the yield strength of 5005A-H24?
5005A-H24 has a typical yield strength of 130 MPa (18.9 ksi) and a tensile strength of 160 MPa (23.2 ksi) — weaker than 73% of aluminum grades. Strength varies by condition: see the 17 listed tempers.
Is 5005A-H24 easy to machine?
Not especially — machinability is rated fair (39/100, worse than 83% of aluminum grades). Soft and gummy — use sharp polished high-rake carbide, high surface speed and generous lubrication to avoid built-up edge; chip breaking is poor in O/H1x tempers.
Can 5005A-H24 be welded?
Yes — weldability is rated excellent (88/100). Excellent by GTAW/GMAW and resistance welding with 5356 or 5183 filler; HAZ softens back toward O-temper so design joints at annealed strength.
What surface finishes work on 5005A-H24?
Purpose-built for anodizing: clear, bright and coloured films come out uniform; also takes chemical conversion coating, powder coat and PVDF paint; mechanical polishing gives good specular finish.
Can 5005A-H24 be formed, bent or molded?
Very good cold formability — deep draw and spin in O/H22/H24; use larger bend radii and cross-grain bending for H16/H18/H36/H38.
What is the maximum service temperature of 5005A-H24?
5005A-H24 is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 5005A-H14 and 5005A-F?
H14 is the default condition — most commonly stocked 5005A sheet: good strength/formability balance for anodized panels and trim. F: hot-rolled/extruded stock with no property guarantee; pick when the part is fully re-formed or annealed later. Yield strength is 150 MPa in H14 versus 45 MPa in F.
