The difference between the aerospace aluminum alloy profiles and ordinary aluminum profile

by:AAG     2020-11-06


the difference between the aerospace aluminum alloy profiles and ordinary aluminum aerospace aluminum is a kind of deformation of ultra high strength aluminum alloy profiles, 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 profiles and ordinary aluminum alloy profiles, for strength, hardness, toughness, fatigue resistance, have higher demand to the plastic. As light quality of aviation aluminum, light effect is remarkable, has replaced the steel and aluminum alloy profile 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. Is there a good variety of the plane with the aluminum alloy profiles. In today's world aviation aircraft structure with mainly of high strength aluminum alloy profile 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 on the beam bars, web, fuselage stringer, 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 profiles 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 profile: common 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 profile: commonly used 6 how a02, high hardness, good corrosion resistance. Manufacturing engine parts, connector, etc. 5, the casting of aluminium alloy profiles: the proportion of small, high corrosion resistance, heat resistance, the manufacturing engine box, etc.
