Most people who are familiar with alloy aluminum plates know that alloy aluminum plates can be divided into seven categories according to their internal alloying elements, starting from the 1xxx series and the 7XXX series. In addition to the 1XXX series is pure aluminum, the other six series have a certain degree of alloying elements, and the alloy elements of 7xxx are the most one series. It contains four elements: aluminum, zinc, magnesium and copper.
The 7075T6 alloy aluminum plate we are going to say today is certainly one of the 7XXX series, but unlike the general 7075 alloy aluminum plate, the 7075T6 alloy aluminum plate is one of the most powerful alloy aluminum plates in the commercial range, and it also has better Corrosion resistance and mechanical properties. In addition, the 7075T6 alloy aluminum plate has good plasticity after solution treatment, and the heat treatment enhancement effect is also excellent. It can maintain high strength at a high temperature of 150 degrees. Similarly, it has good low temperature strength under low temperature conditions, but its welding performance is relatively poor, and there is a tendency for partial stress corrosion cracking. However, its two-stage aging can improve the performance of anti-SCC.
The main alloying element of 7075 is zinc, so the 7075 alloy aluminum plate has extremely high hardness, good mechanical properties, and positive reaction. We have mentioned this before, and it is because of its excellent performance. In the use of the 7075 alloy aluminum plate, we often carry it on the aircraft, the lower wing siding, the purlin and so on. It can be said that the 7075T6 alloy aluminum plate is, in a sense, an alloy-specific aluminum alloy plate, but because of its excellent performance, it can be seen in the processing of some precision instruments.
