The solidus temperature is 502 degrees.

The initial melting temperature is 502 degrees.

2024 aluminum alloy is a kind of high strength hard aluminum, which belongs to Al-Cu-Mg series aluminum alloy. It is mainly used to manufacture all kinds of high-load parts, which can be strengthened by heat treatment and has medium plasticity in quenched and just quenched States.

Main features and application scope: it is a kind of high-strength hard aluminum, which can be strengthened by heat treatment. Moderate plasticity in quenching and just quenching conditions, good spot welding performance, and easy to form intergranular cracks during gas welding. After quenching and cold working hardening, the machinability of the alloy is still good, but after annealing, the machinability and corrosion resistance are low. Anodizing and spraying methods or aluminum coatings are often used to improve their corrosion resistance. It is mainly used to manufacture various high-load parts (but not stamping forgings) such as skeleton parts, skins, partitions, ribs, beams and rivets below 150℃ on aircraft.
