1. What is aluminum alloy bar/ 2024
The aluminum bar/rod is widely used in all walks of life, such as automobiles, ships, aerospace, aviation, electrical appliances, agriculture, mechanical and electrical, household, etc. Aluminum tube has been everywhere in our life.
Copper serves as the primary alloying element in the aluminum alloy 2024 aluminum alloy bar. It is utilized in applications where a high strength-to-weight ratio and exceptional fatigue resistance are necessary. It has moderate machinability and can only be joined by friction welding.
Due to poor corrosion resistance, they are often protected by aluminum or Al-1Zn cladding, although this may reduce fatigue strength. In the old nomenclature system, the 2XXX series alloys were known as duralumin, and this alloy was designated 24ST, 2024. Typically extruded, it is also available in aluminum foil sheets and plates. It is not usually forged.

6. Applications and characteristics of aluminum alloy bar/rod 2024
The Al-Cu-Mg series of aluminum alloys includes the 2024 aluminum alloy bar and rod. The density of the 2024 aluminum alloy bar or rod is 2.73 g/cm. It possesses modest flexibility in the quenched and freshly quenched phases and can be strengthened with heat treatment.
Its primary characteristics and range of applications are as follows: This is a hard, high-strength aluminum that can be reinforced through heat treatment. It exhibits good spot welding ability, mild flexibility in the newly and fully quenched stages, and intergranular cracks when gas welded. Propensity.
After quenching and cold work hardening, the alloy is well-suited for processing. After annealing, the processing efficiency is poor and the corrosion resistance is average. To increase a surface's ability to withstand corrosion, anodizing and coating techniques are frequently used, or an aluminum layer is applied to the surface.
2024 aluminum alloy is mainly used to manufacture various high-load parts and assemblies (but not stamping forgings), such as aircraft frame parts, skins, partitions, ribs, stringers, rivets, and other working parts below 150°C.
