WHAT IS ZINC-ALUMINUM-MAGNESIUM STEEL?
The zinc-aluminum-magnesium coating makes the hot-dip coating have excellent corrosion resistance, wear resistance and processability through the action of aluminum and magnesium.
Can be widely used in various fields.
Zinc-aluminum-magnesium coating products can allow customers who use GI products to directly change the existing processing, assembly, painting and other processes.
Then replace with zinc aluminum magnesium coating.
Zinc-aluminum-magnesium ternary alloy coated steel strip has high corrosion resistance, and its corrosion resistance is more than 5 times that of pure zinc-coated products (GI) with the same coating weight. The corrosion resistance of the cut is especially obvious, which can replace processing and reheating after forming Dip galvanized steel strip.
Types of zinc-aluminum-magnesium coatings
The hot-dip galvanized aluminum-magnesium production line can provide zinc-aluminum-magnesium coated steel strips with three component systems according to the application
The use of different parts and components in the automobile, home appliances and construction industries.
Two spare zinc-aluminum-magnesium hot-dip coating production lines can provide coatings of two component systems at the same time, while stabilizing production
Complete the adjustment of the composition of the zinc-aluminum-magnesium coating, flexible switching, and guarantee the production schedule.
Corrosion Resistance Mechanism of Zinc Aluminum Magnesium Coating
The magnesium (Mg) component in the coating is beneficial to promote the formation of a very stable and well-structured fine protective film-
simonkolleite (Zn5(OH)8Cl2 · H2O), which generates and maintains a film-like covering layer on the surface of the plating layer, thereby exerting excellent corrosion resistance
