Other 5182 tempers and conditions
5182 is also supplied in 6 other conditions. The full side-by-side table is on the 5182 overview.
- H39Cold-worked to extra-hard level then low-temperature stabilized, giving the highest 5182 strip strength with stable properties for can end/tab stock.400 MPa yield · 110 HB
- H19The high-strength can-end and tab stock condition — pick when maximum strength in thin gauge with adequate residual formability for scoring/curling is required.395 MPa yield · 110 HB
- H18Fully cold-worked (8/8 hard) Al-Mg4.5Mn0.4 sheet/strip with very high strength and low ductility, used for can end and tab stock.385 MPa yield · 105 HB
- H48H19-strength coil that is coil-coated on one or both faces; the standard supply condition for beverage-can ends and tabs going straight to the press.385 MPa yield · 108 HB
- H111Standard European sheet condition for formed parts where light levelling/flattening strain is acceptable and O-temper stretcher strains must be reduced.150 MPa yield · 75 HB
- OChoose for maximum drawability — automotive inner panels, deep-drawn shells and stampings that need high uniform elongation.130 MPa yield · 70 HB
Working with 5182-H48
Is 5182 easy to machine?
Soft and gummy in O/H111 — use sharp polished-flute carbide tools, high speed, generous rake and flood lubrication; H19/H48 chips break better but the alloy is normally blanked, not machined.
Can 5182 be welded?
Readily GTAW/GMAW/resistance and laser welded with 5356 or 5183 filler; no post-weld heat treatment needed but the weld zone reverts to near-O strength and high-Mg welds should stay below ~65 °C service.
Can 5182 be formed, bent or molded?
Outstanding stretch/deep-draw formability in O temper (high n-value); expect Lüders/stretcher-strain marks in O and use H111 or a temper roll pass for visible surfaces; H19/H48 is designed for high-speed shell pressing, scoring and curling only.
What surface finishes work on 5182?
Accepts clear/bright anodizing, conversion coating and coil lacquer well; degrease thoroughly since Mg-rich surface oxide forms fast, and pre-etch before painting for reliable adhesion.

5182-H48 — frequently asked
What is 5182-H48 used for?
5182-H48 is typically used for beverage can end stock, pull tabs and easy-open ends, automotive inner door and hood panels, deep-drawn body-in-white inner structures, bottle and container closures and stamped brackets and reinforcements. In short: beverage can lid alloy.
What is the yield strength of 5182-H48?
5182-H48 has a typical yield strength of 385 MPa (55.8 ksi) and a tensile strength of 415 MPa (60.2 ksi) — stronger than 87% of aluminum grades. Strength varies by condition: see the 7 listed tempers.
Is 5182-H48 easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 65% of aluminum grades). Soft and gummy in O/H111 — use sharp polished-flute carbide tools, high speed, generous rake and flood lubrication; H19/H48 chips break better but the alloy is normally blanked, not machined.
Can 5182-H48 be welded?
Yes — weldability is rated excellent (85/100). Readily GTAW/GMAW/resistance and laser welded with 5356 or 5183 filler; no post-weld heat treatment needed but the weld zone reverts to near-O strength and high-Mg welds should stay below ~65 °C service.

What is the maximum service temperature of 5182-H48?
5182-H48 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.
