2024 -T351 Aluminum sheet/plate for aircraft skeleton
Production Introduction
2024 is the typical hard aluminum alloy in the Al-Cu-Mg system, temper T352, its composition is reasonable, comprehensive performance is better, the usage amount is the largest in hard aluminum. High strength, a certain heat resistance, strength is higher than the 7075 alloy. Thermal state, annealing and new quenching state of forming performance are better, heat treatment strengthening effect is remarkable. Corrosion resistance is poor, but cladding with the pure aluminum can be effectively protected; easy to come with the cracks in welding, but using of the special technology can be welded, can also riveting.

Product Features
1.High strength, can be welded, good formability, the effect of heat treatment to strengthen is good;
2.Tensile strength is 400-500Mpa, the heat resistance, anti-fatigue of this alloy is better,
3. Low density, high modulus, good thermal conductivity and good conductivity, good manufacturing process;
4.Good mechanical properties, large strength,so as ease to process, small density, can be used for light structural materials.
Typical Usage
2024 aluminum alloy is widely used in aircraft skeleton (skin, skeleton, ribs, frame, etc.), rivets, military, missile structure, mold, propeller structure and other various structures.
