We supply 5083 H321 Aluminium Sheets & Plates in India for shipbuilding, marine structures, pressure vessels, rail cars, vehicle bodies and other applications where Aluminium Alloy 5083 in the H321 temper is specified. The range includes 5083 H321 aluminium sheet and plate in different thicknesses, widths and lengths, subject to the required standard and material availability.
Our 5083 H321 material is supplied against the specified product requirement, including the alloy, temper, dimensions, quantity and applicable specification. For marine projects, the requirement may also include ASTM B928/B928M and relevant inspection or classification requirements.
5083 H321 Aluminium Sheets & Plates are supplied as flat-rolled aluminium products for applications that require the 5083 alloy in the H321 temper. The material is commonly specified for marine and transport-related applications and is also used for pressure vessels, rail cars, vehicle bodies, tip truck bodies, mine skips and cages.
The product can be supplied as:
5083 is a non-heat-treatable aluminium-magnesium alloy. Published H321 product data identifies it as a marine-grade alloy with good seawater service performance and strong post-weld characteristics.
| Specification | Details |
|---|---|
| Alloy | Aluminium Alloy 5083 |
| Temper | H321 |
| Product Form | Sheets & Plates |
| ASTM / ASME | ASTM B209 / ASME SB209, where applicable |
| Marine Specification | ASTM B928 / B928M, where applicable |
| European Designation | EN AW-5083 |
| UNS | A95083 |
| Werkstoff Number | 3.3547 |
| Alloy Designation | AlMg4.5Mn / AlMg4.5Mn0.7 |
| Surface | Mill finish or as specified |
The applicable specification should be stated in the purchase requirement because ASTM B209 and ASTM B928/B928M apply to different product requirements and service conditions. ASTM B928/B928M specifically covers qualifying high-magnesium aluminium alloy sheet and plate products for marine service, including specified 5083 H321 material.
5083 H321 Aluminium Sheet and Plate dimensions vary according to thickness, mill capability and available stock. The material requirement should therefore specify the required thickness, width and length rather than relying only on the alloy designation.
One established H321 stock range published by Righton & Blackburns includes:
| Published Plate Size | Published Thickness Range |
|---|---|
| 4000 × 2000 mm | 3.0 mm to 25.0 mm |
| 6000 × 2000 mm | 3.0 mm to 40.0 mm |
These are published stock dimensions from that supplier and should not be interpreted as a universal size range for all 5083 H321 suppliers. Other producers and stockholders publish different dimensions depending on their rolling capability and inventory.

*Published sources list GM41 and the other designations in connection with Alloy 5083 but also caution that listed designations may not always represent direct one-to-one equivalents. The required material specification should therefore govern any substitution.
The chemical composition of 5083 H321 is based on Aluminium Alloy 5083. The H321 temper does not change the alloy's specified chemical composition.
| Element | Composition |
|---|---|
| Aluminium (Al) | Balance |
| Magnesium (Mg) | 4.00–4.90% |
| Manganese (Mn) | 0.40–1.00% |
| Chromium (Cr) | 0.05–0.25% |
| Iron (Fe) | 0.40% max |
| Silicon (Si) | 0.40% max |
| Copper (Cu) | 0.10% max |
| Zinc (Zn) | 0.25% max |
| Titanium (Ti) | 0.15% max |
| Other, Each | 0.05% max |
| Other, Total | 0.15% max |
These composition limits are consistently published for Alloy 5083 in sources based on EN 573-3 and Aluminium Association data.
