Size tolerance of aluminum sheet is including the thickness tolerance ,width tolerance,length tolerance and Diagonal tolerance.

a. The width of the shear  aluminium sheet and plate allows deviation.

The width  tolerance of the shear aluminum sheet and plate is allowed to be divided into ordinary and high grade.When a positive or negative symmetry deviation is required in the order contract, the deviation value should be half of the corresponding value.

A.ordinary grade width tolerance of aluminum sheet and plate

 

1. Thickness: 0.2mm-3.0mm  Width tolerance is +2mm/-0mm for width 500mm,Width tolerance is +5mm,/0mm for width 501mm-1250mm,Width tolerance  is +6mm/-0mm for width 1250mm-2000mm,Width tolerance is +8mm/-0mm for width 2000mm-2500mm

2.Thickness: 3.01mm-6.0mm  Width tolerance is +4mm/-0mm for width 500mm,Width tolerance is +6mm/-0mm for width 501mm-1250mm,Width tolerance  is +8mm/-0mm for width 1250mm-2000mm,Width tolerance is +12mm/-0mm for width 2000mm-2500mm

3.Thickness: 6.01mm-12.0mm  Width tolerance is +6mm/-0mm for width 500mm,Width tolerance is +8mm/-0mm for width 501mm-1250mm,Width tolerance  is +8mm/-0mm for width 1250mm-2000mm,Width tolerance is +12mm/-0mm for width 2000mm-2500mm

 

B.high grade width tolerance of aluminum sheet and plate

 

1. Thickness: 0.2mm-3.0mm  Width tolerance is +1mm/-0mm for width 500mm,Width tolerance is +3mm,/0mm for width 501mm-1250mm,Width tolerance  is +4mm/-0mm for width 1250mm-2000mm,Width tolerance is +5mm/-0mm for width 2000mm-2500mm

2.Thickness: 3.01mm-6.0mm  Width tolerance is +3mm/-0mm for width 500mm,Width tolerance is +4mm/-0mm for width 501mm-1250mm,Width tolerance  is +5mm/-0mm for width 1250mm-2000mm,Width tolerance is +8mm/-0mm for width 2000mm-2500mm

3.Thickness: 6.01mm-12.0mm  Width tolerance is +4mm/-0mm for width 500mm,Width tolerance is +5mm/-0mm for width 501mm-1250mm,Width tolerance  is +5mm/-0mm for width 1250mm-2000mm,Width tolerance is +8mm/-0mm for width 2000mm-2500mm

 

b.The width tolerance of the sawing aluminum plate allows deviation.

 

1. Thickness: 2.0mm-6.3mm  Width tolerance is +2mm/-2mm for width 500mm-1000mm,Width tolerance is +3mm/-3mm for width 1000mm-2000mm,Width tolerance  is +4mm/-4mm for width 2000mm-2500mm

 

2.Thickness: 6.31mm-150mm  Width tolerance is +6mm/-6mm for width 500mm-1000mm,Width tolerance is +7mm/-7mm for width 1000mm-2000mm,Width tolerance  is +8mm/-8mm for width 2000mm-2500mm

 

That production standard is suitable for 1000 series aluminum sheet and plate,2000 series aluminum sheet and plate,3000 series aluminum sheet and plate,4000 series aluminum sheet and plate,5000 series aluminum sheet and plate,6000 series aluminum sheet and plate,7000 series aluminum sheet and plate,8000 series aluminum sheet and plate.
