1. What is aluminum alloy pipe 2024
Al-Cu-Mg series alloy 2024 aluminum alloy tube is a type of aluminum alloy. 2024 aluminum alloy tube has a density of 2.73 g/cm. It possesses modest flexibility in the quenched and freshly quenched phases and can be strengthened with heat treatment. Its primary attributes and area of use are as follows: This is a hard, high-strength aluminum that can be heat-treated to become stronger. It exhibits good spot welding ability, mild flexibility in the newly and fully quenched stages, and intergranular cracks when gas welded. Propensity. The alloy has good processability after quenching and cold work hardening. The processing performance after annealing is low and the corrosion resistance is not high. Anodizing and coating methods are usually used, or the surface is coated with an aluminum layer to improve its corrosion resistance.
2024 aluminum is primarily used to create a variety of high-load parts and assemblies (but not stamping forgings), including rivets, skins, ribs, stringers, and other working parts that must withstand temperatures below 150°C.

ⓐ O-annealing
ⓑ H111 - Annealed and slightly strain hardened (less than H11) in subsequent stretching or straining.
ⓒ T3510-solid solution, stress relief + natural aging through controlled stretching (set 0.5%~3% for rolled pipe). The stretched product is no longer straightened.
ⓓ T3511 - Same as T3510 except slight straightening is allowed after stretching to meet standard tolerances.
