5083 aluminum wire is a non-heat-treatable, high-magnesium alloy (AlMg4.5Mn0.7) that sets the standard for corrosion resistance in harsh saltwater and chemical environments. It offers the highest strength among non-heat-treatable aluminum alloys, with excellent weldability and toughness even at cryogenic temperatures. Linsy supplies it in O, H32, and H116 tempers for welding filler and forming.

5083 Aluminum Wire is a non-heat-treatable aluminum-magnesium alloy (AlMg4.5Mn0.7) supplied by Linsy Aluminum. It is one of the strongest work-hardenable grades and is widely specified for marine, offshore, and cryogenic service because of its excellent resistance to seawater corrosion and its ability to retain strength after welding. Common tempers include O, H111, H112, H116, and H321.

5083 is non-heat-treatable — tempers are produced by strain hardening and stabilization, not by solution heat treatment.
Among the best aluminum alloys for seawater and chemical exposure.
The strongest work-hardenable aluminum grade, ideal where weight must be minimized.
Excellent as welding filler; compatible with 5083 and 5086 base metals.
Retains ductility and strength at very low temperatures.
5083 welds well with conventional processes (TIG/MIG) and retains most of its strength in the weld zone. For welding filler, ER5183 or ER5356 wire is commonly used. The alloy has only moderate machinability compared with heat-treatable grades, and cutting tools should account for its gummy chip formation.
Every 5083 order ships with a material test certificate (MTC) that reports the actual chemical analysis and mechanical results for the supplied lot. Third-party SGS test reports are available on request. Standard mill inspections cover dimensional tolerance, surface condition, and tensile verification per the ordered specification.
Linsy Aluminum is a Shenzhen-based aluminum manufacturer with over 20 years of production experience, supplying the 1000–8000 series across plate, bar, tube, wire, coil, profile, and block. For 5083 wire, we support custom dimensions, small minimum order quantities, and short lead times.
Diameter typically ranges from 0.8 mm to 12 mm, with a tolerance of ±0.05 mm and coil weights from 10 kg to 500 kg.
Yes. 5083 wire (and the closely related 5183 filler) is widely used for welding 5xxx marine structures.
O for maximum formability, H32/H116 for higher strength in structural or filler applications.
Custom 5083 orders are usually produced and shipped within 10–60 days, depending on temper, size, and quantity. Contact us with your drawing or specification for a firm schedule.
We support low minimum order quantities for standard tempers and common sizes. Non-standard dimensions are quoted case by case.
Yes. A material test certificate (MTC) is provided with every order, and third-party SGS test reports are available on request.
Mill finish is standard. Anodizing, polishing, powder coating, and PVC film protection can be arranged.
Yes. CNC cutting, sawing, and machining services are available so material arrives closer to your net shape.
