A brief introduction to the alloy aluminum plate has been a lot before, I believe that everyone has a certain understanding of the performance of each series of alloy aluminum plate, but we have also mentioned that in all series of alloy aluminum plate 7XXX alloy Aluminum plates are the most special. Because he has four different elements, it is more than other alloy aluminum plates.
One of the things we are going to say today is the more representative alloy aluminum plate in the 7XXX series, the 7075 alloy aluminum plate. 7075 aluminum plate can be said to be a kind of super-hard alloy aluminum plate material which can be strengthened by heat treatment, has the advantages of convenient casting, good formability and good comprehensive performance. Because alloy aluminum plates often produce various defects such as pores, cracks, undercuts in the welding of metal, especially for those aluminum alloys with ultra-high strength for heat treatment strengthening, welding in arc welding It will be worse, and it is prone to cracks. It can be said that it seriously hinders the use of the original 7075 alloy aluminum plate in the industry. However, because of the many alloying elements of the 7075 aluminum plate, the properties are also the most complicated. After many research and technological innovations, Today's 7075 aluminum plate has already serviced these problems, and it also has high thermal conductivity, oxidation resistance and great strength.
Due to the special performance of this series, the 7075 alloy aluminum plate has not only been greatly developed in the industrial field, but also expanded to the current aerospace military field, whether it is in the manufacture of the current civil space shuttle or in the current military. The manufacture of combat aircraft has played a very important role.
