FAQ of 2024 aluminum round bar
Please ensure the size and quantity before purchasing Chalco 2024 aluminum bars. Then contact our customer service personnel, we will provide you with the best quality products and the most competitive quotations in the market.
Equivalent Grades of 2024 aluminum round bar?
2024, AW-AlCu4Mg1, AU4G1, 3.1355, A92024, AlCu4Mg1, AlCuMg2
Dimensions and weights of 2024 aluminum bar
Calculation of the weight of the aluminum round rod: πR2*h×0.0000027 (3.1415*the square of the radius of the aluminum rod*the length of the aluminum rod*density, the unit of the radius length is mm).
Calculation of the weight of the aluminum square rod: side A*side B*0.0027*h (side length*side length*density*aluminum rod length), the unit is mm.
If the length is short, the cutting loss shall be increased.
The length and width of the cut shall have a tolerance of 1-3mm.
For easier estimation, you can use our aluminum bar weight calculator to quickly compute the theoretical weight of your desired 2024 round or square bar based on dimensions and density.
