1, The higher the purity, corrosion resistance, the better, pure aluminum in the air and the role of oxygen in the aluminum surface will produce a thin layer of dense natural oxide film, generated faster than other metal oxide film and Thick and more, thus preventing the air of harmful gases and water corrosion, played a protective role; aa1100 aluminium sheet coils
2, The corrosion resistance of aluminum is good, (aluminium sheet coil manufacturers)but the mechanical strength is poor, which to a certain extent, restricts the application of aluminum, so people in the aluminum by adding appropriate magnesium, copper, zinc and other metals, made of various types Of the aluminum alloy, aluminum alloy high mechanical strength, the mechanical strength of aluminum greatly improved, greatly expanded the scope of application, although the mechanical strength of aluminum alloy, but the corrosion resistance than aluminum poor, it is possible due to oxidation and corrosion. requires the powder coating to protect aluminum profiles, aluminum alloy with a small proportion, processing is easy, mechanical strength and other characteristics has been widely used in doors and windows;embossed aluminium sheet coil
After powder coating, aluminum has a high corrosion resistance,diversity color , good surface texture and many other advantages, and different exterior wall paint echoes in order to build a colorful gorgeous building.Zhengzhou Haomei Industrial co.,ltd
