What exactly is meant by the term “aerospace aluminum alloy profile”?

The aviation sector makes extensive use of ultra-high-strength deformed aluminum alloy profiles known as aerospace aluminum alloy profiles. These profiles are presently in widespread use. It has excellent processing and mechanical qualities, good plasticity after being treated with a solution, and strong tensile strength after being subjected to heat treatment. In general, it is a suitable structural material due to its high strength and strong toughness below 150 ° C (or even higher), and it can even withstand higher temperatures.

What differentiates aircraft aluminum alloy profiles from regular aluminum alloy profiles is:

When it comes to strength, hardness, toughness, fatigue resistance, and plasticity, the standards for aluminum alloy profiles used in aeroplanes are far more stringent than those for regular aluminum alloy profiles.

Aluminum alloy profiles have taken over the leading role in the aviation industry as a result of the low weight of aircraft aluminum material and the considerable lightweight effect. This has caused aluminum to overtake steel as the material of choice in aviation. Aluminum has more stringent criteria for use, and the aviation industry is a significant and growing high-end application market for metal.

Aerospace manufacturing utilizes a wide variety of different aluminum alloy profile types. The majority of the high-strength 2 series (2024, 2017, 2A12, etc.) and ultra-high-strength 7 series (7075, 7475, 7050, 7A04, etc.) aluminum alloy profiles used in aviation aircraft structures around the world today are ultra-high-strength 7 series (7075, 7475, 7050, 7A04, etc.). Additionally, some 5 series (5A06, 5052, 5086, etc).

Aerospace applications are the primary market for aerospace aluminum alloy profiles.

The most common applications for aerospace aluminum, which is a type of industrial aluminum profile, include the wing skin, the wing truss, the upper and lower edge strips of the spar, the web, the fuselage truss, the seat rail, the keel beam, the side frame, the fuselage skin, the lower fuselage siding, the main floor stringers, and other similar components.

1. Hard aluminium: 

aluminium-magnesium-copper alloy. The profiles of aluminum extrusion alloys that are used in the aviation sector the most often. Regularly used 2024, 2A12, 2017A, has excellent strength, toughness, fatigue resistance, and plasticity, and has a high volume of usage. Used for a variety of things, including skins, bulkheads, and ribs.

2. Super hard aluminium: 

aluminium-zinc-magnesium-copper alloy. Commonly used 7075 aluminum extrusion and 7A09 have a high strength limit and yield strength, and they can handle a big load. These properties allow them to be utilized in the production of the upper wing surface skin, girder, and other similar components.

3. Anti-rust aluminum

Alloy profiles, including the aluminum-magnesium alloys 5A02, 5A06, and 5B05, are the most often used types. It has great resistance to corrosion and fatigue, together with good plasticity and the capacity to be welded. made things like mailboxes and oil pipelines, among other things.

4. Forged aluminium 

Alloy profiles: 6A02 is a popular choice due to its high level of hardness and its excellent resistance to corrosion. manufacture of engine components, joints, etc.

5. Casting aluminium

Alloy profiles, which have a low specific gravity, great resistance to heat and corrosion, and are used in the production of engine casings, among other things.
