2024 aluminum alloy Al-Cu-Mg aluminum alloy, the main features and applications: This is a high-strength hard-aluminum, heat treatment can be strengthened in the quenched and just hardened plastic medium, spot welding is good, with gas welding When there is a tendency to form intergranular cracks, the alloy hardened and hardened in the hardenability of its Machinability is good, low machinability after annealing: corrosion resistance is not high, often using anodic oxidation and painting methods or surface with aluminum Layer to improve its anti-corrosion ability.
Tensile Strength ?b( MPa): ≥470
Yiled Strength ?0.2(MPa): ≥325
Elongation δ5(%): ≥12
1. High strength hard aluminum;
2. Good welding characteristics;
3. Good cutting characteristics;
4. Low density, good processing performance;
Uses Mainly used for making all kinds of high-load parts and components (but not including stampings forgings) such as aircraft parts on the skeleton, skin, bulkheads, ribs, spars, rivets and other working parts below 150 ℃.
