Sometimes shipyard staff will find that the contact between aluminum alloy and wood will produce corrosion phenomenon when they overhaul the ship. We all know that 5083 aluminum plate is corrosion-resistant. Why will corrosion phenomenon occur?Next 5083 aluminum plate manufacturers to introduce the specific reasons for you.

Unreasonable structure corrosion

5083 Aluminum hull structure shall not have water "dead corner".For example, China once had a 5083 aluminum hydrofoil mounted on the side of a hydrofoil support box in the shape of a "disc" with a protective cover and "dead corners" at both ends.At ordinary times and not easy to carry out maintenance, "dead Angle" part of the side of 5083 aluminum plate outside the board is generally seriously affected by corrosion.If the structure is improved to eliminate the blind spot, the outer aluminum will not corrode the aluminum 5083.

Improper arrangement of rivet holes can also cause serious corrosion. Due to too large rivet spacing at the bottom of the speedboat bulkhead, water in the bilge dipped into the gap and corroded the 5083 aluminum plate at the bottom.

Stray current corrosion

When a ship is docked with steel cables and piers to conduct electricity, stray electricity will flow through the water to the hull structure and become corroded.Precautions: Use wires to connect the welder to the welded part.

The above is the cause of corrosion between 5083 aluminum plate and wood, I hope to help you, if you need to understand the price of 5083 aluminum plate, you can consult us.
