Working with 5652-H32
Is 5652 easy to machine?
Gummy Al-Mg chip — use sharp polished high-rake carbide, high speed, generous lubricant to avoid built-up edge; better finish in H34/H38 than O.
Can 5652 be welded?
Excellent GTAW/GMAW with ER5356 or ER5654 filler (ER5654 preferred for peroxide/high-temperature service); HAZ reverts toward O strength, so design welds to annealed properties.
Can 5652 be formed, bent or molded?
Very good cold formability in O and H32; allow generous bend radii in H36/H38 and consider interstage annealing at 345 °C for deep draws.
What surface finishes work on 5652?
Anodizes well (clear/hardcoat, slightly grey tone); passivation and scrupulous cleaning are mandatory for hydrogen-peroxide tank interiors; paints and conversion coatings adhere readily.

5652-H32 has a typical yield strength of 195 MPa (28.3 ksi) and a tensile strength of 230 MPa (33.4 ksi) — stronger than 50% of aluminum grades. Strength varies by condition: see the 8 listed tempers.
Is 5652-H32 easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 65% of aluminum grades). Gummy Al-Mg chip — use sharp polished high-rake carbide, high speed, generous lubricant to avoid built-up edge; better finish in H34/H38 than O.
Can 5652-H32 be welded?
Yes — weldability is rated excellent (90/100). Excellent GTAW/GMAW with ER5356 or ER5654 filler (ER5654 preferred for peroxide/high-temperature service); HAZ reverts toward O strength, so design welds to annealed properties.
What surface finishes work on 5652-H32?
