Densitatea aluminiului: 2.702 g/cm3. Densitatea plăcii de aluminiu: densitatea plăcii de aluminiu pur este 2.71 g/cm3, iar densitatea plăcii din aliaj de aluminiu este 2.68 g/cm3. Calitatea plăcii de aluminiu = grosimea plăcii de aluminiu * lăţime * lungime * densitate.
Weight = thickness * lăţime * lungime * densitate / 1000000 (în mm), de exemplu: A 2.5 gros 1060 placa de aluminiu, theoretical weight = 2.5 * 1220 * 2440 * 2.71/1000000 = 20.16KG.
There are shortcut methods: (1), 2.5*1.22*2.44*2.71=20.16KG: gros (mm) * 1.22 * 2.44 * density = large plate theoretical weight, large plate refers to 4 * 8 feet specifications, both 1220mm * 2440mm. (2) Grosime (mm)*1*2* Density = small plate theoretical weight, small plate finger 1*2 is 1000mm*2000mm. Remarks: 1 foot = 305 mm.
The writing method of the coil: ca 2.0 thick aluminum coil, because the width of our company's conventional aluminum coil is 1220mm wide, so it is: 2.0*1220*C.
