Aerospace aluminum plate is an ultra high strength deformed aluminum plate, which is widely used in aviation industry. It has good mechanical and processing properties, good plasticity after solution treatment, good heat treatment and strengthening effect, generally below 150 (?) C with high strength and toughness, is an ideal structural material.
Compared with ordinary aluminum sheet,
aircraft aluminum plate has 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 dominant position of current aviation materials. Aviation equipment has a high demand for aluminum materials and is an important high-end application market for aluminum products.
There are many kinds of aluminum plates used on aircraft. Nowadays, the aluminum sheets used for aircraft structures in the world are mainly 2 series (2024, 2017, 2A12, etc.) of high strength and 7 series (
7075 Aerospace aluminum plates,
7475 Aerospace aluminum plates,
7050 Aerospace aluminum plates,
7A04 Aerospace aluminum plates, etc.) of super high strength, and some 5 series (5A06, 5052, 5086, etc.) and 6 series (6061, 6082, etc.) of other series aluminum materials.
Aerospace aluminum plates are mainly used in wing skin, wing truss, upper and lower flange of wing beam, web, fuselage truss, seat slide rail, keel beam, side frame, fuselage skin, fuselage lower panel, main floor truss and other parts.
1. Hard aluminum: Al mg Cu alloy. The most widely used aluminum sheet in aviation industry. Commonly used 2024, 2A12, 2017A, strength, toughness, fatigue resistance is good, plasticity is good. It is used to make skin, frame, rib and so on.
2. Super hard aluminum: aluminum zinc magnesium copper alloy. Commonly used 7075, 7A09, high strength limit and yield strength, bearing large loads, used to make the upper wing skin, girder, etc.
3, rust proof aluminum plate: commonly used Al Mg alloy 5A02, 5A06, 5B05. It has high corrosion resistance, fatigue resistance, good plasticity and weldability. Used to make mailboxes, tubing and so on.
4, forging aluminum plate, commonly used 6A02, high hardness, good corrosion resistance. Manufacturing engine parts, joints and so on.
5, cast aluminum plate, small gravity, corrosion resistance, high heat resistance, manufacturing engine casing.
