Alloy aluminum coil is a variety of alloy elements added to the aluminum plate processing, in order to improve the mechanical properties of aluminum coil and chemical indicators. Alloy aluminum plate has a pure aluminum plate does not have some special properties, widely used in special environments, such as ships, refrigerators, molds, aerospace equipment and so on.

So how to identify quality during the purchase process? Let's learn more about it together.

How to identify the quality of alloy aluminum plate? To judge the quality of alloy aluminum plate first of all, we should pay attention to the surface finish, the general quality of good products its finish is very good, but also to observe whether the board thin is uniform, pinch the board with the hand, feel the elasticity and toughness is good.

Its main function is to make the moisture in the hot air in the heat transfer sheet condensed into water droplets easy to spread and follow the sheet to the dirty. Alloy aluminum plate Moisture permeability is low, with excellent moisture-proof function, with safety, Bento and long shelf life of the excellent characteristics, alloy aluminum plate According to the main alloy elements can be divided into 2xxx system aluminum copper alloy aluminum plate (AL--CU), 3XXX system is aluminum manganese alloy aluminum plate (AL--MN), 4xxx system is aluminum silicon alloy aluminum plate ( AL--SI), 5xxx is aluminum magnesium alloy aluminum plate (AL--MG), 6xxx system is aluminum magnesium silicon alloy aluminum plate (AL--MG--SI), 7xxx system is aluminum zinc alloy aluminum plate [al--zn--mg--(Cu)].
