5657 h242 anodizing quality aluminum sheet

In many cases, aluminum coils and sheets are processed by anodizing. For example, in all kinds of high-grade electronic and electrical housings, chassis, cabinets need to improve the corrosion resistance of aluminum sheet coil by anodizing, then, what alloy aluminum sheet or coil suitable for anodizing?

5657 h242 anodizing quality aluminum sheet is very suitable for anodic oxidation, but in anodic oxidation is the need for users to pay attention to a few points in order to ensure a better effect.

The first is the material of the base plate. The 5657 h242 anodizing quality aluminum sheet is needed as the base plate to achieve better surface effect. If cold-rolled aluminum sheet coil is used, water ripple will occur.

The second is the control of anodic oxidation time. The main purpose of anodic oxidation is to obtain the oxide film. The longer the oxidation time, the higher the thickness of the oxide film, the higher the cost.

Third, the surface scratch problem, some aluminum anodizing sheets manufacturers oxidation equipment automation is not too high, often need to be manually oxidized, this time to pay attention to avoid scratches, otherwise it will affect the quality of the plate.
