8082 aluminum is a medium-strength 8000-series grade with an aluminum–magnesium lean chemistry that delivers good corrosion resistance and moderate mechanical properties. It is suited to applications needing a balance of formability, weldability, and durability rather than peak strength. Linsy supplies 8082 in O, H14, and H18 tempers across sheet, bar, and tube, with custom dimensions and MTC documentation for every order.
Available forms: sheet / plate / bar / tube
Common tempers: O / H14 / H18
Processing support: CNC machining / bending / welding / anodizing
Quality documents: MTC report with every order
8082 is a general-purpose 8000-series alloy positioned between the soft forming grades and the high-strength structural alloys. Its lean magnesium addition improves strength and corrosion resistance over pure-aluminum grades while keeping good workability, making it useful for welded assemblies, enclosures, and architectural parts.
Typical production ranges are listed below; custom dimensions are available on request.

| Tube | O, H14, H18 | Outer Diameter | 10 – 300 mm | Wall 1 – 30 mm |
| Element | Composition (%) |
|---|---|
| Magnesium (Mg) | 4.0 – 5.0 |

| Aluminum (Al) | Remainder |
| Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Note |
|---|---|---|---|---|
| O | 110 – 150 | 70 – 110 | 12 – 20 | Soft, weldable |
| H14 | 160 – 200 | 130 – 170 | 5 – 12 | Half-hard |
| H18 | 200 – 240 | 170 – 210 | 4 – 8 | Full-hard |
Good general and atmospheric corrosion resistance, suitable for indoor and light outdoor use.
Reasonable weldability and formability in O temper support fabricated assemblies.
Medium strength — above pure aluminum but below 5xxx/6xxx structural grades; pick per load case.
8082 can be cut, bent, and welded with standard aluminum practice. Avoid over-aging during welding by controlling heat input. Anodizing gives a uniform decorative finish; specify temper and post-weld treatment for appearance-critical parts.
Every shipment is accompanied by an MTC report detailing chemical composition and mechanical test results. Third-party inspection and SGS test reports can be arranged on request. Incoming and outgoing inspection covers dimensions, surface condition, and mechanical properties.
Linsy operates a Shenzhen production base with over 20 years of aluminum manufacturing experience, supplying 1000–8000 series alloys to global B2B buyers. We support custom dimensions, tempers, and processing for both prototype and production volumes.

Medium-strength fabricated and welded parts, enclosures, and architectural panels where corrosion resistance matters more than peak strength.
Yes, it has reasonable weldability in O temper; control heat input to avoid softening.
It is medium strength — adequate for light structural and tubing use, but 5xxx/6xxx grades are better where high load is expected.
Standard sizes are usually available within 10–60 days depending on alloy, temper, and order volume. Confirm exact timing with our sales team when requesting a quote.
Yes. We cut to customer-specified thickness, width, length, diameter, and wall thickness where the production process allows.
An MTC report is included with every order. Additional third-party or SGS reports can be arranged on request.
Common options include mill finish, anodizing, polishing, and specialized coatings subject to alloy and application.
