Working with 5654-H32
Is 5654 easy to machine?
Gummy in O/H112 — use sharp polished high-rake carbide, high speed, generous soluble-oil or alcohol-based lubricant; strain-hardened tempers chip much better.
Can 5654 be welded?
Excellent GTAW/GMAW behaviour with 5654 or 5356 filler; keep interpass temperature low and avoid prolonged >65 °C exposure to prevent Mg2Al3 grain-boundary sensitisation.
Can 5654 be formed, bent or molded?
Very good cold formability in O/H32; allow generous bend radii in H36/H38 and consider inter-anneal at 340 °C for severe drawing.
What surface finishes work on 5654?
Anodises to a clear-to-grey film and takes conversion coating and paint well; keep tooling and pickling baths free of copper and iron for peroxide-service parts.

5654-H32 — frequently asked
What is 5654-H32 used for?
5654-H32 is typically used for hydrogen peroxide storage tanks, high-purity chemical piping welds and semiconductor fluid handling. In short: copper-free peroxide-service alloy; highest formability here; filler wire and sheet.
What is the yield strength of 5654-H32?
5654-H32 has a typical yield strength of 205 MPa (29.7 ksi) and a tensile strength of 270 MPa (39.2 ksi) — stronger than 54% of aluminum grades. Strength varies by condition: see the 7 listed tempers.
Is 5654-H32 easy to machine?
Not especially — machinability is rated fair (42/100, worse than 77% of aluminum grades). Gummy in O/H112 — use sharp polished high-rake carbide, high speed, generous soluble-oil or alcohol-based lubricant; strain-hardened tempers chip much better.
Can 5654-H32 be welded?
Yes — weldability is rated excellent (92/100). Excellent GTAW/GMAW behaviour with 5654 or 5356 filler; keep interpass temperature low and avoid prolonged >65 °C exposure to prevent Mg2Al3 grain-boundary sensitisation.
What surface finishes work on 5654-H32?
Anodises to a clear-to-grey film and takes conversion coating and paint well; keep tooling and pickling baths free of copper and iron for peroxide-service parts.
Can 5654-H32 be formed, bent or molded?
Very good cold formability in O/H32; allow generous bend radii in H36/H38 and consider inter-anneal at 340 °C for severe drawing.
What is the maximum service temperature of 5654-H32?
5654-H32 is rated for continuous use to about 65°C (149 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 5654-O and 5654-H38?
O is the default condition — default for formed sheet/plate in hydrogen-peroxide and chemical tankage where maximum ductility and lowest sensitisation risk are wanted. H38: maximum strain-hardened strength for flat or minimally formed parts; bending is limited and SCC caution applies. Yield strength is 115 MPa in O versus 270 MPa in H38.
