The development of modern science and technology is getting faster and faster, and it is advancing by leaps and bounds in the chemical industry. It is not difficult to find out the development of alloy aluminum sheets in recent years. The contribution of the chemical industry to modern industry cannot be underestimated.
The alloy aluminum plate can be mainly divided into six categories according to the elements of the alloy. They are copper-aluminum alloy aluminum plate (Al--Cu), aluminum-manganese alloy aluminum plate (Al--Mn), aluminum-silicon alloy aluminum plate (Al--Si), aluminum-magnesium alloy aluminum plate (Al--Si), aluminum-magnesium-silicon alloy Aluminum plate (AL--Mg--Si) and aluminum-zinc alloy aluminum plate [AL--Zn--Mg--(Cu)]; and alloy aluminum plate can be divided into four categories according to the number of alloys, respectively Alloy binary alloy aluminum plate, ternary alloy aluminum plate, quaternary alloy aluminum plate and multi-alloy aluminum plate; etc. In addition, the alloy aluminum plate can be divided into two categories according to whether it can be strengthened after heat treatment, respectively, heat treatable alloy aluminum plate and non-heat treatable Strengthened alloy aluminum plate. The heat-resistant and strengthened alloy aluminum plate means that it can only be processed and strengthened by cold treatment, but the effect of heat treatment strengthening is not obvious.
Although there are many methods for classifying alloy aluminum sheets, the first method used in the daily sale and purchase of alloy aluminum sheets is the method of classifying alloy aluminum sheets according to different synthetic elements. of. Usually divided by four digits, the first digits are mainly 2, 3, 4, 5, 6, and 7, representing different elements. For example, the 7050 aluminum plate refers to one of aluminum-zinc alloy aluminum plates [AL--Zn--Mg--(Cu)]. The 6061 aluminum plate is a kind of aluminum-magnesium-silicon alloy aluminum plate (AL--Mg--Si), and so on, each aluminum plate has its own different digital code corresponding to the name.
