Anti-oxidation measures for 3003 aluminium coil storage

The common pipe insulation and anticorrosion with 3004 and 3003 aluminum coil more, 0.4-1.2mm in thickness,1000-1220mm in width, 3003 and 3004 series are aluminum manganese alloy, is a kind of widely used antirust aluminum, the market circulation now most of the sheet and coil/strip shape, because the coil roll in the transport and delivery, storage, easy water oxidation, so 3003 aluminum coil packing storage requirements more stringent.

The 3003 and 3004 aluminum coils belong to the 3000 series aluminum plate sheet,the representative models of the 3 series aluminum plate are 3003, 3004 and 3A21, which can also be called antirust aluminum plate. 3xxx series aluminum sheet is widely used in pipeline insulation and automobile fuel tank industry. 3 series is commonly used in aluminum alloy, with manganese aluminum alloy main alloy elements, non heat strengthened; good plasticity, good welding performance, corrosion resistance is stronger than the 1xxx series which belong to a kind of medium strength of aluminum alloy sheet.

Anti-oxidation measures for 3003 aluminium coil storage:

(1) to strengthen the management of the dry air, ensure no water in the compressed air.

(2) to strengthen the management of rolling oil, the water content of control under 0.04%.

(3) the packing of aluminum foil coil should be sealed and the proper amount of desiccant should be placed in each roll.

(4) the humidity of the wooden shaft and the box is not more than 18%, and the temperature of the packed aluminum coil is not more than 45 degrees centigrade.

(5) from the low temperature zone to high temperature, high humidity area, don’t open the seal packing immediately.

(6) workshop, warehouse roof leak rain, snow, should not be placed high quality aluminum coil.
