Introduction of galvanized aluminum magnesium sheet

The coating of the zinc-aluminum-magnesium-nickel rare earth alloy coating plate is caused by the high temperature solidification of zinc (Zn), aluminum (A), and magnesium (Mg), and its microstructure is composed of Zn, A and Zn2Mg. Therefore, the surface layer of the thick steel plate forms a high-density natural barrier that effectively prevents the passage of corrosion elements. Compared with general galvanized steel sheet, its quality characteristics and advantages are mainly reflected in four aspects

1. Super corrosion resistance:

Aluminum alloy elements such as A, Mg and S Bo are added to the coating of hot-dip galvanized aluminum-magnesium steel plate, which further improves the actual effect of coating corrosion inhibition. Excellent corrosion resistance, 1020 times that of hot-dip galvanized steel.

2. Self-recovery

The coating components near the cutting surface are continuously mixed, resulting in a high-density protective film mainly composed of zinc hydroxide, partial alkali zinc chloride and aluminum hydride. Suppress the actual effect

3. Long life

Because of its high corrosion resistance ability to achieve 10-0 times that of ordinary hot-dip galvanized sheet and the self-healing effect of corrosion resistance of cutting cross-section, the prefabricated components made of hot-dip galvanized aluminum-magnesium-steel-aluminum alloy coating plate are in active service. Of course, the service life will be longer, and under normal conditions, it can be more than 30 years.

4. Easy production and processing:

The coating of hot-dip galvanized aluminum-magnesium steel plate is higher than that of galvanized steel plate, so it is not easy to cause the coating to detach during the processing of stamping parts, and it has excellent drawing, stamping die, sheet metal bending, Production processing characteristics such as electric welding and welding, and because of the high strength of the coating, it has extraordinary damage resistance.
