Zinc Aluminum-magnesium Coated Steel

A new kind of corrosion-resistant coated steel sheet called zinc aluminum-magnesium coil is made primarily of zinc, around 11% aluminum, 3% magnesium, and trace amounts of silicon. Steel sheet coated with a highly corrosion-resistant zinc, aluminum, and magnesium alloy is known as Z-A-M. Z-A-M possesses exceptional corrosion resistance, scratch resistance, and formability because of the impacts of the metals magnesium and aluminum.

 

1. It has better corrosion resistance, which is several times to ten times higher than that of galvanized sheet within a certain range

2. It has a low friction coefficient and stable friction characteristics, which is very beneficial to stamping, and can reduce the wear of the coating, thereby reducing the lack of roughness of the parts.

3. It has good welding performance, because the addition of magnesium can reduce the spatter near the weld seam during laser welding and improve the welding performance.

Production specification: 0.4~2.0x1000~1600 Coating thickness: 60~450g/㎡ (both sides) Surface treatment: passivation, anti-fingerprint, oil coating

Varieties include: Low carbon steel: DC51D+ZM DC52D+ZM DC53D+ZM

Duplex steel: HCT450X+ZM, HCT590X+ZM

Zinc-aluminum-magnesium products are widely used, mainly used in civil construction (keel ceiling, perforated plate, cable tray), agriculture and livestock (steel structure of agricultural feeding shed, steel structure accessories, greenhouse, feeding equipment), railway road, power communication (transmission Power distribution high and low voltage switchgear, box-type substation outer body), photovoltaic support, automobile motor, industrial refrigeration (cooling tower, large outdoor industrial air conditioner) and other industries, the application field is very wide.
