2024 aluminum sheet is a typical hard aluminum alloy in the aluminum-copper-magnesium series. Its composition is relatively reasonable and its comprehensive performance is better. Many countries produce this alloy, which is the largest amount of duralumin. The characteristics of the alloy are: high strength, certain heat resistance, and can be used as working parts below 150 °C. 2024 aluminum alloy with a density of 2.85 g/cm3.

2 represents the 2000 series, 2024 aluminum is the most widely used aluminum alloy in the 2024 series, and the 2XXX series is a typical hard aluminum alloy in the aluminum-copper-magnesium series. Its composition is relatively reasonable and its comprehensive performance is better.
0 indicates the control of the limit content of alloying elements or impurities: 0 indicates the original alloy, indicating that its impurity limit content has no special control, 1-9 modified alloy, indicating that there is a limit to one or more single impurities or alloying elements. special controls.
24 means different alloys: it means the two digits after the decimal point in the minimum aluminum alloy content, such as 1050 aluminum content is 99.50%, the two digits have no special meaning, and are only used to identify different alloys in the same group.
T represents heat treatment. T is usually followed by one or more digits, such as T3, indicating that T3 heat treatment has been carried out. Different numbers represent different heat treatments.

Calculation formula of 2024 aluminum alloy
Aluminum sheet weight (kg)=0.00000285×thickness×width×length
Aluminum tube weight (kg) = 0.0000028 × wall thickness × (outer diameter – wall thickness) × length
Aluminum bar weight calculation formula (kg) = 0.00000285 × radius × radius × length * 3.14
