Different Types of Aluminum Grade

Aluminum alloys are widely suitable in engineering structures and components where light weight or corrosion resistance is required.

Alloys composed mostly of aluminum have been very important in aerospace manufacturing since the introduction of metal-skinned aircraft.

Aluminum alloys typically have an ultimate tensile strength ranging from 310 MPa (45,000 psi) to 690 MPa (100,000 psi).

There are many different types of aluminum alloys, each with its properties and applications. Here are a few of the most common:

Wrought Aluminum Alloys

These alloys are suitable for various applications that require good formability, weldability, and/or corrosion resistance. Examples include the popular 6061 alloy, which is often suitable for transportation and structural applications, and the 1000 series alloys, which are commonly suitable for chemical processing equipment.

The 1100 aluminum sheet and 1100 aluminum coil are both available for various applications including chemical storage & containment, heat exchangers, electrical enclosures, architecture, stamping, and more.

Aluminum 3003

3003 aluminum is a 3000 series aluminum alloy: the main alloying addition is manganese, and it is also commonly known as an anti-rust aluminum alloy.

3003 aluminum sheet metal is widely used in truck beds and trailers, as well as for storage tanks. The alloys in the 3000 series are easy to weld and have excellent corrosion resistance.

Aluminum 3105

3105 aluminum is a wrought aluminum alloy with good corrosion resistance, weldability, and electrical conductivity. It also has good formability and machinability. It is often used in electrical applications because of its high conductivity.

3105 aluminum has good weldability and formability, making it a popular choice for use in electrical applications. It is also frequently used in architectural applications due to its corrosion resistance and aesthetic appeal.

Aluminum 5052

5052 aluminum is a 5000-series aluminum alloy: the main alloying addition is magnesium, and it is formulated for primary forming into wrought products. Typical applications include marine, automotive, and aerospace industries. In the as-fabricated (no temper or treatment) condition, it has good weldability.

Aluminum 6061

6061 is one of the strongest aluminum alloys. Its strength-to-weight ratio is excellent, and it is also very resistant to corrosion. 6061 is widely used in the construction of aircraft and other structures where lightweight and strong structural integrity is required.

Aluminum 6063

6063 aluminum is a precipitation-hardening alloy that combines very high strength with good formability. It has the highest strength of any 6000 series aluminum alloy. In addition, it has good weldability and corrosion resistance.

6063 aluminum can be heat treated to enhance its strength. However, it is not as strong as some other alloys in the 6000 series.6063 aluminum is mostly used in extruded products that have intricate designs.

These products include windows, doors, fencing, furniture, and railing. It is also used for pipe and tubing applications.

Aluminum 7075

Aluminum 7075 is a high-strength alloy that contains zinc as the primary alloying element, with smaller amounts of magnesium, copper, and chromium. It has excellent mechanical properties, making it one of the strongest aluminum alloys available.
