Except thickness, width and length, there are still many other aluminum sheet measurement standards. The number which is closely connected with thickness is the aluminum sheet metal thickness tolerance. Generally speaking, the smaller the thickness tolerance is, the higher the aluminum sheet quality is. In haomei Aluminum, we always work hard on improving our technology. Now, the thickness tolerance can reach to ± 0.005 mm in our company.

After determining aluminum sheet metal sizes, next standard is aluminium sheet grades. There are mainly 8 aluminium alloy series. The more commonly used aluminum sheet are 1000, 3000 and 8011. This three aluminium alloy sheet are all provided in haomei Aluminum.

The third standard is the temper, which means the difference of aluminum sheet hardness. The main product of haomei Aluminum is H temper. H indicates the aluminum sheet is strain hardened during the production process. In addition, there are two or more numbers following the H letter, which means the different digits of strain hardening.
