The material of the china 2mm aluminium sheet is usually 1000, 2000, 3000, 5000, 6000 and 7000 series aluminum alloys. The 2mm aluminium sheet is a common seen 4x8 Aluminum Sheet thickness, and the thickness range of aluminium sheet product is usually 1-300mm. The allowable thickness tolerance of the national standard aluminum sheet is plus or minus 0.02mm. The price of the china 2mm aluminum sheet depends on the alloy grade, temper, the size is different, the price is also different.
There are many specifications and models of aluminum sheet materials, and they are widely used. Among the product quality of aluminium sheet, the thickness control can be an evidence to prove the strength of the aluminium sheet manufacturer. The allowable deviation of the china 2mm aluminium sheet needs to be determined according to the width of the aluminum sheet:
Width (mm) Thickness tolerance (mm)
400～600 ±0.15
600~800 ±0.20
800~1000 ±0.20
1000~1220 ±0.24

The china 2mm aluminium sheet belongs to thin aluminum sheet product, 3mm, Aluminum Sheet 5mm, 6mm and 8mm are also the common used thickness. The thin aluminium sheet is processed by rolling processing, include cold rolling and hot rolling. Medium thick aluminum plates must be cut with large sawing equipment in production tolerances, so the width and length tolerances usually require a 5mm allowance. Compared with thin aluminum sheets, the tolerance of precision leveling machines is small, but for medium thick aluminum plates cannot be leveled. Only large sawing equipment should be used. In terms of thickness tolerance, our company can control it at around 0.1mm. Usually, the medium and thick aluminum plate is a mold, which is needed for mechanical parts and needs to be milled later, so our company usually goes to the tolerance range.
