Reasons for Corrosion of Aluminum Plates

The reasons for the corrosion of aluminum plates may be:

Acids, alkalis or water remain on the surface of the aluminum plates during production.

The kerosene emulsion that the aluminum plates contact, these auxiliary materials contain water or alkalinity, causing corrosion,

The unsealed packaging causes corrosion,

The anti-corrosion layer is damaged during transportation and corrosion will also occur.

The reasons for copper diffusion are:

Incorrect heat treatment system, if the temperature is too high or the time is too long, it will cause copper diffusion;

Repeated heat treatment too many times, abnormal heat treatment equipment, will also cause copper diffusion in the aluminum plate;

Improper rolling operation during hot rolling, too thin aluminum coating is also a reason.
