aerospace aluminum is a kind of deformation of ultra high strength aluminum alloy, has been widely applied in aviation industry. It has good mechanical and processing properties, good plasticity after solid solution treatment and heat treatment strengthening effect is good, is in commonly 150 ℃ ( Even higher) The following has high strength, good toughness, is the ideal structural material. Aircraft compared with aluminum alloy and ordinary aluminum alloy, the strength, hardness, toughness, fatigue resistance, have higher demand to the plastic. As light quality of aviation aluminum, industrial aluminum lightweight effect is remarkable, has replaced the steel and to dominate the current aviation materials. The requirements of the aviation equipment for aluminum is higher, is one of the important high-end aluminum application market. Aluminum alloy has a good variety of the plane. In today's world aviation aircraft structure with aluminum alloy is mainly high strength (2 2024, 2017, 2 a12, etc. ) And 7 series of ultra-high strength ( 7075, 7475, 7050, 7 a04, etc. ) And another part 5 series ( 5 a06, 5052, 5086, etc. ) And 6 ( 6061, 6082, etc. ) And a small amount of other series aluminum. Aerospace aluminum is mainly used in the wing surface skin, long wing plane girder, edge of wing beams, web, fuselage stringer, industrial aluminum seat slide rail, keel beam and side frame, the fuselage skin, the bottom wall plate, the main floor purlin and parts. 1, hard aluminum: aluminum magnesium copper alloy. The most widely used aluminum alloy in the airline industry. Commonly used 2024, 2 a12, 2017 a, better strength, toughness, fatigue resistance, good plasticity. Used to make skin, bulkhead, ribs, etc. 2, super-hard aluminum: aluminum zinc magnesium copper alloy. Commonly used 7075, 7 a09, ultimate strength and yield strength is high, the load bearing, used to make the wings on the wing surface skin, girder, etc. 3, antirust aluminium alloy: commonly used 5 how a02 aluminum magnesium alloys, 5 a06, 5 b05. Has high corrosion resistance, fatigue resistance, good plasticity and weldability. Used to make a mailbox, tubing, etc. 4, forging aluminum alloy: commonly used 6 how a02, high hardness, good corrosion resistance. Manufacturing engine parts, connector, etc. 5, the casting of aluminium alloy: the proportion of small, high corrosion resistance, heat resistance, the manufacturing engine box, etc.
