What are the characteristics of magnesium aluminum zinc plate?

Magnesium aluminum zinc plate is the leading technology developed by famous international steel enterprises in recent years. In particular, ArcelorMittal, the largest steel enterprise in the world, has promoted its research and development achievements to the fields of automobile special plates, home appliances and so on. The corrosion resistance of magnesium aluminum zinc plating is mainly reflected in the formation of a variety of complex metallic phase Zn-MgZn₂ binary eutectic and Zn-Ai-MgZn₂ ternary eutectic in the high temperature melting bath. The eutectic grains are fine with nano characteristics, which effectively block the penetration of external atoms into the coating interior, enhance the adhesion between the coating and the substrate, and play a good role in corrosion prevention.At the same time, there are many active magnesium elements in the plating solution. When the microstructure of the plate coating solidifies, it reacts with oxygen in the air to form a magnesium-containing oxide layer. This oxide layer can remain stable in the long-term corrosive environment and improve the corrosion resistance of the product.Magnesium aluminum zinc plating also has the self-repairing function of cutting end face and welding end, which can well inhibit the corrosion of the exposed part.
