2024 Aluminum Plate / Aluminum Coil

Introduction of 2024 Aluminum Plate:

2024 aluminum plate is a typical hard aluminum alloy in the Al-Cu-Mg system. Its composition is reasonable and its comprehensive performance is good. This alloy is produced in many countries and is the largest used in hard aluminum. The alloy is characterized by high strength and a certain heat resistance, and can be used as a working part below 150 °C. 2024 aluminum alloy, density is 2.85 g/cm3.
The 2024 alloy grade was registered by the United States in 1954. The temperature is higher than 125 ° C, and the strength of the 2024 alloy is higher than that of the 7075 alloy. The forming properties are better in the hot state, annealing and new quenching conditions, and the heat treatment strengthening effect is remarkable, but the heat treatment process is strict. Corrosion resistance is poor, but it can be effectively protected by coating with pure aluminum; it is easy to crack when welding, but it can be welded or riveted by special process.

Main Features of 2024 Aluminum Plate:

The main features of 2024 aluminum plate: This is a kind of high-strength hard aluminum, which can be heat-treated and strengthened. It has medium plasticity in quenching and quenching state, good spot welding, and there is a tendency to form intergranular cracks during gas welding. The alloy has good machinability after quenching and cold hardening. The machinability is low after annealing: the corrosion resistance is not high. The anodizing treatment and painting method or the surface of the aluminum layer is often used to improve the corrosion resistance.

Main Use of 2024 Aluminum Plate:

2024 aluminum plate is mainly used to make various high-load parts and components (but not stamping forgings) such as skeleton parts, skins, partitions, ribs, spars, rivets and other working parts below 150 °C.
