Detailed Guide to 6082 Aluminium Plate: Composition, Properties, and Uses
Product Description
The 6082 aluminium plate belongs to the 6××× series (Al-Mg-Si) alloy, renowned for being heat-treatable and strengthened. It offers an excellent balance of medium strength, good welding performance, and superior corrosion resistance. This alloy is primarily utilized in the transportation and structural engineering industries where durability and a lighter weight are crucial.
Due to the rapid development of modern industries, especially shipbuilding, 6082 alloy is becoming a go-to material to reduce hull dead weight and improve vessel speed, making it an ideal material for manufacturing high-speed ship components.

Casting Process Overview
The manufacturing of 6082 alloy requires precise control, primarily due to its manganese (Mn) content, which is a refractory metal [user provided text].
- Melting Temperature: Controlled between 740–760℃ to ensure complete melting.
- Purification: The melt undergoes nitrogen and refining agent treatment at 735–745℃ to degas and remove slag.
- Filtration: Two filtration stages are utilized: a 30 PPI foam ceramic filter board at the furnace mouth and a 14-mesh fiberglass cloth to catch oxides during casting.
- Casting Conditions: Requires a relatively high casting temperature, low casting speed, and high water flow rate to prevent failure.
Relevant Technical Standards
- National Standard: GB/T 3880-2006 (Standard applicable to unified aluminum strip material) [user provided text].
Surface Treatment Options
6082 aluminum plates can be supplied as non-painted or painted products, depending on the application requirements [user provided text].
- Non-Painted Products:
- Hammer Aluminum Plate: No regular pattern.
- Embossed Plate: Features a regular pattern.
- Pre-Passivated Alumina Surface: Treated surface.
- Characteristics: Lower price, suitable where aesthetic appearance is not critical.
- Painted Products (Coated):
- Coating Processes: Spray plate products and pre-roll coating plate.
- Paint Types: Polyester, polyurethane, polyamide, modified silicon, epoxy resin, fluorocarbon (PVDF).
- Characteristics: Fluorocarbon paint (PVDF) is most commonly used for excellent UV resistance.
Primary Applications
- Bridges
- Cranes
- Roof frames
- Transport planes
- Transport ships and high-speed ship parts
- Structural Engineering
