The difference between aerospace aluminum alloy and ordinary aluminum alloy

aerospace aluminum is a kind of ultra-high strength deformed aluminum alloy, which is widely used in the aerospace industry at present. It has good mechanical and processing properties, good plasticity after solution treatment and good heat treatment strengthening effect. Generally, it has high strength and good toughness below 150 ℃ (or even higher). It is an ideal structural material for HRD

compared with ordinary aluminum alloys, aluminum alloys for aircraft have higher requirements for strength, hardness, toughness, fatigue resistance and plasticity. Due to its light weight and remarkable lightweight effect, aviation aluminum has replaced steel and occupied the leading position of current aviation materials. Aviation equipment has high requirements for aluminum, which is an important high-end application market of aluminum

there are many kinds of aluminum alloys used in aircraft. Nowadays, the aluminum alloys used in aviation aircraft structures in the world are mainly high-strength 2-Series (2024, 2017, 2A12, etc.) and ultra-high-strength 7-series (7075 74@A Surrounding environment 75, 7050, 7A04, etc.), in addition, there are some 5-series (5A06, 5052, 50, 88 more people than B787 (8), 6-series (6061, 6082, etc.) and a small amount of other series of aluminum

aerospace aluminum materials are mainly used in wing skin, wing stringers, upper and lower edge strips of wing beams, webs, fuselage stringers, seat rails, keel beams, side frames, fuselage skin, fuselage lower wall panels, main floor stringers and other parts

1. Duralumin: aluminum magnesium copper alloy. Aluminum alloy is the most widely used in aviation industry. 2024, 2A12, 2017A are commonly used, with good strength, toughness, fatigue resistance and plasticity. It is used to make skin, partition frame, wing ribs, etc

2. Superhard aluminum: aluminum is easy to operate, zinc magnesium copper alloy. 7075 and 7A09 are commonly used. They have high strength limit and yield strength and bear large loads. They are used to manufacture upper wing skin and girders of wings

3. Antirust aluminum alloy: commonly used aluminum magnesium alloys 5A02, 5A06, 5B05. It has high corrosion resistance, fatigue resistance, good plasticity and weldability. Used to make mailbox, oil pipe, etc

4. Forged aluminum alloy, commonly used 6A02, has high hardness and good corrosion resistance. Manufacturing engine parts, connectors, etc

5. Cast aluminum alloy, with small specific gravity, high corrosion resistance and heat resistance, can be used to manufacture engine casings, etc
