National standard aluminum plate calculation formula
1. Calculation formula
The weight of the aluminum plate = the thickness of the aluminum plate * width * length * density
2. Aluminum plate density
The density of pure aluminum is 2.7×10kg/m³ or 2.7g/cm³; other series vary from 2.58 to 2.9 depending on the alloy. For details, please refer to the aluminum density table at the bottom.
Examples of how to choose aluminum plate thickness
Assuming the volume V of the aluminum plate with a length of 728mm, a width of 380mm and a thickness of 3.0mm: V=3.0mm*0.728*0.38 The weight of the aluminum plate: V*2.7g/cm³=2.24kg
National standard A6061 aluminum plate standard hardness
O: (annealed state) hardness HB around 30-35
T6: (basically stable state of artificial aging after solution heat treatment) hardness HB 90-95
T4: (Basic stable state of natural aging after solution heat treatment) Hardness is about HB 65
