Working with 5005-H16
Is 5005 easy to machine?
Soft and gummy — use sharp polished high-rake carbide, high speed, generous coolant/lubricant to avoid built-up edge; harder H18/H38 tempers machine cleaner.
Can 5005 be welded?
Excellent by GTAW/GMAW and resistance welding; use 5356 or 5183 filler (1100/4043 acceptable for low-stress joints) — weld zone reverts to near-O strength.
Can 5005 be formed, bent or molded?
Very good cold formability in O/H32/H34; allow generous bend radii above H16 and expect springback; not heat treatable, so strength comes only from cold work.
What surface finishes work on 5005?
Best-in-class bright and colour anodizing (architectural AA-M12C22A31/A41); also takes chromate/chem-film, powder coat and paint well; polishes to a uniform satin or mirror finish.

5005-H16 — frequently asked
What is 5005-H16 used for?
5005-H16 is typically used for architectural curtain-wall and cladding panels, decorative trim and sign faces, electrical enclosures and covers, anodized appliance and equipment panels, cooking utensils and vessels and nameplates and instrument fascias. In short: beautiful anodizing; marine grade.
What is the yield strength of 5005-H16?
5005-H16 has a typical yield strength of 172 MPa (24.9 ksi) and a tensile strength of 179 MPa (26 ksi) — weaker than 56% of aluminum grades. Strength varies by condition: see the 16 listed tempers.
Is 5005-H16 easy to machine?
Reasonably — machinability is rated fair (48/100, worse than 67% of aluminum grades). Soft and gummy — use sharp polished high-rake carbide, high speed, generous coolant/lubricant to avoid built-up edge; harder H18/H38 tempers machine cleaner.
Can 5005-H16 be welded?
Yes — weldability is rated excellent (88/100). Excellent by GTAW/GMAW and resistance welding; use 5356 or 5183 filler (1100/4043 acceptable for low-stress joints) — weld zone reverts to near-O strength.
What surface finishes work on 5005-H16?

Can 5005-H16 be formed, bent or molded?
Very good cold formability in O/H32/H34; allow generous bend radii above H16 and expect springback; not heat treatable, so strength comes only from cold work.
What is the maximum service temperature of 5005-H16?
5005-H16 is rated for continuous use to about 120°C (248 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
