About The Corrosion Resistance Of Aluminum Corrugated Panel

  • We can see Aluminum Corrugated Panel in many buildings, so why is Aluminum Corrugated Panel so popular?

    After the aluminum chemically reacts with oxygen in the air, a firm and dense oxide film will be formed on the surface. This layer of oxide film becomes the anti-corrosion "coat" of aluminum, which makes it difficult for the aluminum inside to be oxidized by oxygen in the air. Therefore, the corrosion depth of aluminum is less than 100,000 minutes after being placed in the atmosphere for a year One millimeter. If aluminum and steel are put into a container containing 3% sodium chloride and 1% hydrogen chloride at the same time, and the corrosion test is carried out for 70 hours, the average weight loss of steel is 11.07 milligrams per square centimeter, while the average weight loss of aluminum is 0.675 mg per square centimeter, which proves that the corrosion resistance of aluminum greatly exceeds that of ordinary steel. However, the natural oxide film of aluminum still has the shortcomings of being thin and soft, and its anti-corrosion performance is not very strong. Therefore, the service life of the untreated aluminum corrugated board is generally only about 20 years.

    The Aluminum Honeycomb Panel is the same, the service life can be very long, sturdy, and durable.
