Precautions for the use of QQ-A-250/9 5456 aviation aluminum plate

Before use, carefully check whether there are obvious defects or damage on the surface of the aluminum plate. If any problem is found, it should be replaced in time.

According to the use environment and requirements of the product, select the appropriate state and size to avoid problems such as insufficient mechanical properties and poor corrosion resistance during use.

When processing aluminum plates, appropriate tools and techniques should be used to avoid problems such as cracks and deformation, which will affect the service life and performance of aluminum plates.

During the use of the aluminum plate, avoid long-term exposure to humidity, high temperature or corrosive gas, so as not to affect the corrosion resistance of the aluminum plate.

During use, attention should be paid to the cleaning and maintenance of the surface of the aluminum plate to avoid contamination or scale on the surface, which will affect the aesthetics and corrosion resistance of the aluminum plate.

If the aluminum plate is found to be abnormal during use, stop using it in time, and contact the supplier or manufacturer for inspection and maintenance.
