3003 alloy plate cost is five times more than the cost price of iron, preferably fridge chose the high cost of the evaporator coil embossing alloy is aluminum because the evaporative cooling effect is the best.
3003 alloy aluminum coil aluminum coil is a series of commonly used products, high manganese alloy coil elemental composition, good rust resistance, commonly used in the more humid environments aluminum coil in the cold rolling process.
When an aluminum alloy contaminated with difficult to remove the asphalt on the volume, if the general cleaning agents to no avail, tried to clear a brush, but do not use excellent brush, especially iron brush, so as not to damage the surface of the aluminum coil.
When the high temperature alloy steel coil, should be allowed to cool before cleaning, do not use cold water to wash. Otherwise, alloy coil would be damaged.
In addition, at high temperatures with a detergent to clean aluminum coil, make the surface chemical reaction, lose their luster, affecting appearance. If the place where the vehicle is wet, aluminum coil should be cleaned frequently to avoid salt corrosion of aluminum surfaces due to roll and aluminum coil surface friction and rolling, the surface will produce fine aluminum powder off and adsorption, rolling oil and its accompanying suspension components will remain on the surface of the aluminum alloy composite coil, painting and other finished products resulting Negative Effects.
