Aluminium equal angle (also known as L-shaped aluminum profile) is a kind of aluminum alloy profile with excellent strength and corrosion resistance, which is widely used in the manufacture of ship structures and fittings. 5086 and 6061 aluminium equal leg angle are two important aluminum alloy materials, which have a wide range of applications in the shipbuilding industry.

The 5086 and 6061 aluminium equal angle profiles for shipbuilding have different characteristics and applications, which are suitable for different shipbuilding needs. The following is a detailed introduction about these two kinds of aluminum alloy materials:

1. 5086 Aluminium Equal Angle

- Performance characteristics:

5086 aluminum alloy is a rustproof aluminum with good corrosion resistance, weldability and medium strength.

It will not be strengthened by heat treatment, but will become stronger by strain hardening or cold mechanical processing of the material.

Corrosion resistance in atmosphere and seawater is comparable to that of pure aluminum and is suitable for marine environments.

- Uses:

5086 aluminum equal edge is used in the shipbuilding industry to make hull structural members, decks, bulkheads, etc., because of its excellent corrosion resistance and weldability.

It is also suitable for other applications that require high corrosion resistance and moderate strength, such as weldable parts for automobiles and pressure vessels that require strict fire protection.

2. 6061 Aluminium Equal Angle

- Performance characteristics:

Aluminum alloy 6061 has a good combination of properties, including medium strength, good corrosion resistance, weldability and machinability.

It can be heat-treated to improve mechanical properties such as tensile strength and yield strength.

6061 aluminum alloy also has good toughness and fatigue resistance.

- Uses:

In the shipbuilding industry, 6061 aluminium equal angle is commonly used to make hull structural parts, support structures, frames, etc., because it has high strength and good corrosion resistance.

It is also widely used in other industrial fields, such as machinery manufacturing, textile machinery, auto parts, etc.

The specifications of aluminium equal angle profiles can be customized according to the design requirements, common side lengths and thicknesses include:

- Edge length: e.g. 20mm, 30mm, 40mm, etc.

- Thickness: e.g. 3mm, 5mm, 10mm, etc.

Advantages of aluminium angle bar in shipbuilding industry including:

- Lightweight: Aluminum alloy has low density, and the hull structure made with aluminum alloy can reduce the weight of the ship, thus improving the fuel economy and speed of the ship.

- Corrosion resistance: aluminum alloy has excellent corrosion resistance in the atmosphere and seawater, which can extend the service life of the ship and reduce the maintenance cost.

- Machinability: Aluminum alloy is easy to cut, stamping, cold bending, forming and cutting, which is suitable for manufacturing complex hull structures.

- Weldability: aluminum alloy has good welding performance, which can ensure the firmness and safety of hull structure.

In summary, 5086 and 6061 aluminium equal angle has a wide range of application prospects in the shipbuilding industry. They have excellent performance characteristics and advantages, and can meet the requirements of shipbuilding industry for light weight, corrosion resistance and processability.
