Before we introduced a lot of alloy aluminum plates for everyone, we all know that the alloy aluminum plates are divided into seven categories according to the different types of alloys. From the beginning of 2 to 8, these seven types of alloy aluminum plates are in our daily industrial production. It can be said that there is nowhere to be seen, but everyone must have a question, that is, since it is a number, why is there no alloy aluminum plate of the 1XXX series? Is it starting from 2?
In fact, there is no 1XXX series that starts with 1 . However, in a strict sense, the 1XXX series cannot be regarded as an alloy aluminum plate. It can only be said to be a simple aluminum plate. The 1XXX series aluminum plate refers to those aluminum content that is up to 100%. Ninety-nine high-purity aluminum sheets. Therefore, the 1XXX series is not an alloy aluminum plate. Therefore, we say that the alloy aluminum plate refers to the seven types of alloy aluminum plates of the 8XXX series starting from the 2XXX series.
Well, after explaining the problems of the 1XXX series, we still come back to look at the 4XXX series alloy aluminum plate. In the 4XXX series, 4A01 can be said to be one of the most representative alloy aluminum plates, which contains silicon compared to other The series of aluminum plates are relatively high, usually between 4.5 and 4.5%, and are very wear-resistant and heat-resistant, which is more suitable for the processing of building materials and mechanical parts.
The 5XXX series of alloy aluminum plates are more representative, there are 5052, 5005, 5083 alloy aluminum plate series and so on. The main element of this series of alloy aluminum plates is magnesium, which is usually controlled between three and five percent. The density is relatively low, but the tensile strength is high and the elongation is high. Also because of its low density, it is relatively light in the 5XXX series alloy under the same area. So usually spare on the aircraft fuel tank.
