2024 aluminium sheet is a typical hard aluminium alloy in the Al-Cu-Mg series with very high strength. 2024 aluminium sheet is a typical hard aluminium alloy in the Al-Cu-Mg series with very high strength. It is most used in 2 series alloys. When the temperature is higher than 125℃, its strength is higher than that of 7075 alloy. In addition, the heat treatment strengthening effect of the 2024 aluminum 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 aluminum alloy is strict. 

Applications and Features:

1. Heat Resistance. 2024 aluminium sheet has good heat resistance, can be used for working parts below 150℃.

2. Mechanical Properties. 2024 aluminium 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 aluminum alloy is relatively poor, but anodizing treatment and painting methods, or pure aluminum coating can improve its corrosion resistance. In addition, the 2024 aluminium 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.

The Use of 2024 Aluminum Sheet/Plate

Routine Application

In general, 2024 aluminum sheet is mainly used to make various high-load parts and components (non-stamping parts and non-forgings). Including automotive, truck wheel hubs, molds, rivets, propeller elements and various other structural applications.

2024 Aluminum Sheet for Aircraft Manufacturing

The high-end 2024 aluminum sheet is a high-strength deformed aluminum for aerospace. Its strength, hardness, toughness, fatigue resistance, and plasticity meet the requirements of aviation materials. At present, 2024 aluminum alloy is mainly used to manufacture skeleton parts, skins, bulkheads, ribs, spar, rivets and other working parts below 150 ℃ on aircraft.
