Advantages of the production method of Haomei 5383 aluminum alloy sheet

The high-magnesium 5383 aluminum alloy sheets for sale are prepared by Haomei's 5383 aluminum alloy stabilization process. Due to the addition of Zr element on the basis of the 5083 alloy composition, the Zr element can combine with the Al element to form an Al3Zr phase with a size of about tens of nanometers. This Al3Zr phase can effectively pin the dislocations, subgrain boundaries and grain boundaries in the 5383 aluminum alloy, thereby significantly improving the strength and recrystallization temperature of the 5383 aluminum alloy sheet. Therefore, compared with 5083 aluminum alloy, 5383 aluminum alloy has higher strength and better welding performance.

Considering the cost performance and processing cost of 5383 aluminum alloy sheet, the addition of Zr in 5383 aluminum alloy is about 0.1%. The increase of zr element only increases the cost per ton of 5383 aluminum alloy by about 10 $, and the cost only increases slightly. Therefore, the 5383 aluminum alloy sheet has the potential to replace the 5083 aluminum alloy sheets. The reason why the 5383 aluminum alloy prepared by the traditional process is prone to corrosion failure is that the al3mg2 phase in the 5383 aluminum alloy is easy to precipitate and distribute continuously along the grain boundary. Among them, the potential difference between Al3Mg2 and 5383 aluminum alloy substrates is quite different, and they are preferentially corroded in a corrosive environment. If it is continuously distributed along the grain boundary, the grains are prone to fall off after being corroded, making the 5383 aluminum alloy sheet corrosion failure. If the al3mg2 phase in the 5383 aluminum alloy is intermittently distributed, the corrosion failure will not extend to the aluminum alloy matrix, and the corrosion resistance is better than when the Al3Mg2 is continuously distributed along the grain boundary. Therefore, the key to improving corrosion resistance is to make Al3Mg2 intermittently distributed along the grain boundaries. Haomei's process changes the distribution state of al3mg2 by adjusting the amount of cold rolling deformation of 5383 aluminum alloy sheet and the temperature and time of heat treatment, so that the al3mg2 phase in 5383 aluminum alloy is intermittently distributed and improves the corrosion resistance of 5383 aluminum alloy plate.
