Knowledge

Aviation aluminum is a kind of aluminum alloy profile, which is called a high-quality product among aluminum alloy profiles. The 5 series aluminum alloy profile has the higher strength among all aluminum alloy profiles, so it is suitable for the aerospace industry. The 6-series aluminum alloy profile has a medium strength, and the basic needs of production and manufacturing can be considered.

The grades and characteristics of aviation aluminum:

1. Duralumin: aluminum-magnesium alloy copper. The shipping industry uses common aluminum alloy profiles. Common 2024, 2A12, 2017A, good compressive strength, ductility, fatigue relief, and good plastic deformation. Used in the production of skins, bulkheads, wing ribs, etc.

2. Super hard aluminum: aluminum-zinc-magnesium alloy copper. Commonly used 7075 and 7A09, with high ultimate strength and tensile strength, bear a large load, used in the production of aircraft wing upper wing surface skin, building beams, etc.

3. Anti-rust treatment aluminum alloy profile: common titanium magnesium aluminum alloy 5A02, 5A06, 5B05. It has high corrosion resistance, fatigue relief, excellent plastic deformation, and electric welding weldability. Used in the production of automobile fuel tanks, oil pipelines, etc.

4. Aluminum alloy profile, common 6A02, with high strength and excellent corrosion resistance. Manufacture of engine parts, connectors, etc.

5. Aluminum alloy casting, small proportion, high corrosion resistance, high temperature resistance, production of diesel engine casings, etc.
