Working with 5082-H116
Is 5082 easy to machine?
Gummy, long-chipping alloy — use sharp polished-flute carbide tools, high rake, high speed and flood coolant or MQL to prevent built-up edge; harder H3x tempers cut cleaner.
Can 5082 be welded?
Readily GMAW/GTAW welded with 5183 or 5356 filler; do not use 4000 series Si fillers (brittle Mg2Si), and keep interpass temperature low to limit sensitization.
Can 5082 be formed, bent or molded?
Excellent deep-drawing and stretch forming in O/H111; watch for Lüders (stretcher-strain) markings on annealed sheet — use temper-rolled or stabilized H2x/H3x for visible surfaces.
What surface finishes work on 5082?
Anodizes clear and bright and takes marine-grade sulphuric anodize well; brushed and painted finishes are common, flux brazing is not recommended due to the high Mg content.

What is 5082-H116 used for?
5082-H116 is typically used for deep-drawn can ends, tank trucks, pressure vessels, automotive body panels, storage tanks and marine hull and deck structures. In short: marine-grade plate alloy.
What is the yield strength of 5082-H116?
5082-H116 has a typical yield strength of 215 MPa (31.2 ksi) and a tensile strength of 305 MPa (44.2 ksi) — stronger than 58% of aluminum grades. Strength varies by condition: see the 18 listed tempers.
Is 5082-H116 easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 65% of aluminum grades). Gummy, long-chipping alloy — use sharp polished-flute carbide tools, high rake, high speed and flood coolant or MQL to prevent built-up edge; harder H3x tempers cut cleaner.
Can 5082-H116 be welded?
Yes — weldability is rated excellent (85/100). Readily GMAW/GTAW welded with 5183 or 5356 filler; do not use 4000 series Si fillers (brittle Mg2Si), and keep interpass temperature low to limit sensitization.
What surface finishes work on 5082-H116?
Anodizes clear and bright and takes marine-grade sulphuric anodize well; brushed and painted finishes are common, flux brazing is not recommended due to the high Mg content.

What is the maximum service temperature of 5082-H116?
5082-H116 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.
Can FabDigit make parts in 5082-H116?
Yes — 5082-H116 is available for CNC machining and sheet metal; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
