What is 5182-O?

5182-O is 5182 in the O temper — choose for maximum drawability — automotive inner panels, deep-drawn shells and stampings that need high uniform elongation. 5182-O has a yield strength of 130 MPa (18.9 ksi) and a tensile strength of 275 MPa (39.9 ksi) — weaker than 74% of aluminum grades. Elongation at break is 21% and the elastic modulus is 70 GPa (10.2 Msi). 5182-O has a density of 2.65 g/cm³ (0.0957 lb/in³), lighter than 90% of aluminum grades. It melts at 577°C (1,071 °F).

Chemical & Environmental3

Corrosion resistance is very good (72/100), better than 83% of aluminum grades.

Galvanic Potential (seawater, vs SCE)-0.86 V
Corrosion ResistanceVery good72/100
Chemical Resistance SummaryVery good in neutral and mildly alkaline media, atmospheric and marine exposure; attacked by strong acids and strong alkalis; avoid prolonged exposure above ~65 °C where Mg2Al3 grain-boundary precipitation can cause intergranular and stress-corrosion attack; good compatibility with beverage/food contact after lacquering.

Sustainability4

Producing a kilogram of 5182-O takes about 200 MJ of energy and emits 12.5 kg of CO₂ — less than 60% of aluminum grades. Typical recycled content is 55%.

Working with 5182-O

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-O — frequently asked

What is 5182-O used for?

5182-O 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-O?

5182-O has a typical yield strength of 130 MPa (18.9 ksi) and a tensile strength of 275 MPa (39.9 ksi) — weaker than 74% of aluminum grades. Strength varies by condition: see the 7 listed tempers.

Is 5182-O easy to machine?

Not especially — machinability is rated fair (35/100, worse than 86% 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-O 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 surface finishes work on 5182-O?

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.

Can 5182-O 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 is the maximum service temperature of 5182-O?

5182-O 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.
