5000 series aluminum alloy is an aluminum alloy with magnesium as the main alloying element. It has good corrosion resistance, weldability and formability and is widely used in ships, automobiles, construction, pressure vessels and other fields. The main representative grades of 5000 series aluminum include 5052, 5083, 5086, 5754, 5005, 5A05, etc.
The following are some common 5000 series aluminum alloy grades:
1. 5052 aluminum alloy:
- Features: Medium-strength aluminum alloy with good corrosion resistance, weldability and formability, high fatigue strength and good seawater resistance.
- Application: Commonly used to manufacture products with high strength requirements, such as automobile body panels, ship structures, etc.
- Processing performance: Suitable for sandblasting process, but not suitable for chemical sandblasting and matte treatment.
2. 5083 aluminum alloy:
- Features: High-strength aluminum alloy with good corrosion resistance and weldability, suitable for marine environment.
- Application: Commonly used in the manufacture of ships, low-temperature oil tanks, pressure vessels, etc.
3. 5005 aluminum alloy:
- Features: Similar to 5052 aluminum alloy, but slightly lower in strength, with good oxidation resistance and corrosion resistance, often used for coated aluminum.
- Application: Commonly used in the manufacture of decorative parts, building materials, etc.
4. 5A05 aluminum alloy:
- Features: High-strength aluminum alloy with good corrosion resistance and weldability.
- Application: Commonly used in the manufacture of aerospace structural parts, automotive parts, etc.
5. 5086 aluminum alloy:
Similar to 5083 aluminum alloy, it has high strength and good corrosion resistance, but provides higher strength, suitable for ships, marine engineering and cryogenic equipment.
6. 5754 aluminum alloy:
Commonly used in the automotive industry, especially in body structures, with good formability and corrosion resistance.
Features of 5000 series aluminum alloys including:
- Low density: Under the same area, the weight of 5000 series aluminum alloy is lower than that of other series aluminum alloys, suitable for weight-sensitive application scenarios.
- High tensile strength: It has excellent mechanical properties and high tensile strength, suitable for structural parts that need to bear a certain load.
- High elongation: It has good ductility and is easy to process into various shapes.
- Good corrosion resistance: The addition of magnesium improves the corrosion resistance of aluminum alloys and is suitable for use in humid or corrosive environments.
- Good welding performance: It is easy to weld, the welded joint has high strength, and it is suitable for structural parts that need to be welded.
Good fatigue resistance: It has excellent fatigue resistance and is suitable for parts that bear alternating loads.
- Non-heat-treatable strengthening: 5000 series aluminum alloys cannot be strengthened by heat treatment, but can only be strengthened by cold processing (such as rolling and stretching).
Application areas of 5000 series aluminium alloys:
- Shipbuilding: Due to its excellent corrosion resistance, it is widely used in hulls and ship structures.
- Aerospace: Used to manufacture aircraft fuel tank ducts, aircraft structural parts, etc.
- Automotive industry: Used for parts such as body, fuel tank and chassis.
- Construction industry: Used for curtain walls, doors and windows, roofs and other building decoration materials.
- Pressure vessels: Used to manufacture various pressure vessels and storage tanks.
- Electronic appliances: Used to manufacture electronic equipment housings, radiators, etc.
- Other fields: used to manufacture lawn mower handles, sports equipment, etc.
Comparison with other series of aluminum alloys
