magnesium-aluminum-zinc plating: For example, galvanizing and aluminum-zinc plating have anti-corrosion and anti-rust properties that cannot be compared with magnesium-aluminum-zinc plating. Compared with galvanized sheets, under the same coating conditions, magnesium-aluminum-zinc plating is used The period is 10 to 20 times that of galvanizing.
Advantages and disadvantages of zinc-aluminum-magnesium sheets, comparison of corrosion resistance with other coating types! 1 Comprehensive data comparison The salt spray resistance test of the flat part is similar to that of galvanized silicon plate, which is about 10 to 20 times that of galvanized plate and 5 to 8 times that of galvanized 5% aluminum alloy. The salt spray resistance test of the cut section, bent section and scratched section is better than that of galvanized silicon plate, galvanized 5% aluminum plate and galvanized plate. The ammonia resistance is 2 times that of galvanized sheets and 10 times that of galvanized silicon sheets. The acid and alkali resistance is similar to that of galvanized plate, and better than galvanized silicon plate and galvanized 5% aluminum plate. When the coating is 90g/m2, the corrosion resistance is more superior than the 560g/m2 coating obtained by hot-dip plating after processing into the workpiece. 2ZAM plate salt spray test comparison. The red rust occurrence time of ZAM plate and other three common coatings during the salt spray test is shown in the figure above. It can be seen that the ZAM plate has the longest red rust occurrence time.
What are the benefits of zinc-aluminum-magnesium sheets? What should you pay attention to when purchasing! A zinc-aluminum-magnesium coating has been developed abroad. This steel plate has demonstrated strong competitiveness as soon as it appeared. Zinc, aluminum, and magnesium is an alloy metal that refers to a coated steel plate with a certain amount of Al and Mg added to the existing hot-dip galvanized coating. It is an alloy metal with excellent comprehensive properties.
Advantages of zinc-aluminum-magnesium products. Galvanized aluminum-magnesium steel plate is a new type of highly corrosion-resistant coated steel plate. Its coating composition is mainly zinc, which is composed of zinc plus 5% to 11% aluminum, 5% to 3% magnesium and trace amounts of silicon. Composition (the proportions of different manufacturers are slightly different). Currently, the thickness range that can be produced in China is 0.40mm, and the width range that can be produced is: 580mm1500mm.
Zinc, aluminum and magnesium is an alloy metal that is used to prevent corrosion on the surface of steel and steel products. Galvanized aluminum-magnesium plate is a plate that was successfully developed in 2000 in order to replace stainless steel products and improve the performance of galvanized plates. Its advantages are reduced cost, good corrosion resistance of the incision, and automatic repair. It has good processing performance, environmental protection and long service life, and is corrosion-resistant.
Advantages of ZAM board: The anti-rust performance is 1020 times that of galvanized board (meeting the stainless steel standard), reducing the cost (generally 40% cheaper than stainless steel), and the incision has good corrosion resistance (the incision can be automatically repaired to prevent the occurrence of red show, one of the characteristics ) Good processing performance (due to its excellent wear resistance and scratch resistance, it can be adapted to various processing) Environmental protection (passed multiple international environmental protection tests) The thickness, strength and amount of galvanizing can be adjusted, long life It has better corrosion resistance, which is several to more than ten times higher than that of galvanized sheet within a certain range. It has a low friction coefficient and stable friction characteristics, which is very beneficial to stamping and can reduce the amount of coating wear, thereby reducing the roughening of parts.
