The characteristics of the 2 XXX series alloy aluminum plate
2 XXX is alloy aluminum plate is Cu alloy aluminum alloy elements, it includes Al - Cu - Mg alloy aluminum plate, Al - Cu - Mg - Fe - Ni alloy aluminum plate, Al - Cu - Mn alloy aluminum plate, etc., these alloy aluminum plate all belong to the heat treatment can strengthen the alloy aluminum plate.
Faith on aluminum production department of XXX alloy aluminum plate is characterized by: high strength, often referred to as hard alloy aluminum plate, the heat resistance and processing performance is good, but good corrosion resistance than other alloy aluminum plate, under certain conditions can produce intercrystalline corrosion, therefore, plank often require coating a layer of pure aluminum, or a layer of core board with electrochemical protection 6 XXX series alloy aluminum sheet, in order to greatly improve its corrosion resistance. Of Al - Cu - Mg - Fe - Ni alloy has a very complex chemical composition and phase composition, it has high strength at high temperatures, and have good process performance, is mainly used to working under 150 ~ 250 ℃ heat resistant parts; Al - Cu - Mn alloy at room temperature strength while lower than that of Al - Cu - 2024 Mg alloy and 2 a14, but in 225 ~ 250 ℃ or higher intensity of temperature is higher than the two, and alloy process performance is good, easy to welding, is mainly used in heat can be welded structures and forging. Department of alloy are widely used in aviation and aerospace fields.
