2024 aluminium sheet is a typical hard aluminium alloy (Al-Cu-Mg). It has a more reasonable composition and better overall performance. It has the largest amount of market.
Characteristics of the alloy: high strength, great resistance of heat which can be used below150°C. The alloy 2024 has a higher strength than 7075 alloys if the temperature is over 125°C. With the heat treatment, annealing and quenching conditions, it has better formability. The effect of heat strengthening is obvious, but the processing is really strict with a high standard. In addition, the heat treatment strengthening effect of the 2024 aluminium sheet is the most significant, whether it is in the hot state, annealed or newly hardened, Its formability and machinability are very good. However, the heat treatment process of 2024 aluminium alloy is strict.Its processing technology far exceeds national standards. It is widely used in moulds, rivets, truck wheels and other various structural parts.

The Features of 2024 Aluminium Sheet
1. Heat Resistance. 2024 aluminium sheet has good heat resistance, can be used for working parts below 150℃.
2. Mechanical Properties. 2024 aluminum sheet tensile strength is 470Mpa, 0.2% yield strength is 325Mpa, fatigue strength is 105Mpa, elongation is 12%, and hardness is 120HB.
3. Other Characteristics. It should be noted that the corrosion resistance of 2024 aluminium alloy is relatively poor, but anodizing treatment and painting methods, or pure aluminium coating can improve its corrosion resistance. In addition, the 2024 aluminum sheet is prone to cracks during gas welding and requires a special process for welding. It can also be riveted, and spot welding is good.
