If you want to know how many pieces aluminum sheet per ton, you must know the weight of each aluminum sheet.
Then, let’s take 1/8″ 4 x 8 aluminum sheet as an example to calculate the weight of a single aluminum sheet..
The density of pure aluminum is 2.7g/cm³ (2700kg/m³).
Unit conversion:
Width: 4 foot = 1219mm = 121.9cm
Lengh: 8 foot = 2438mm = 243.8cm
Thickness: 1/8″ = 3.18 mm = 0.318cm
The weight of one piece 1/8″ 4 x 8 aluminum sheet is:
121.9cm * 243.8cm * 0.318cm * 2.7g/cm³ = 25516.9223g ≈ 25517g = 25.517kg
Because 1/8 inch is 0.125 inch, a 4x8 sheet of 125 aluminum weight is also 25.517kg

The pieces of 1/8″ 4 x 8 aluminum sheet per ton :
4x8 sheet of 1/8 aluminum weight is 25.517kg.
1000kg / 25.517kg = 39.189 pieces ≈ 39 pieces.
So there are about 39 pieces per ton of 1/8″ 4 x 8 aluminum sheet.
how much does a 4x10 sheet of 032 aluminum weight ?
The same calculation method, we can calculate that a 4x10 sheet of 032 aluminum weight is approximately equal to 8.16kg
