Aluminium Alloy AW 5754
Alloy 5754 aluminum plate has excellent corrosion resistance
The 5083 aluminum plate sheet falls on the aluminium alloy group with magnesium and slight contents of manganese and chromium. 5083 aluminum sheet is highly resistant to corrosion from seawater and industrial chemicals and retains exceptional strength after being welded. The product is also known as marine aluminium plate 5083, for the simple reason that it is a typical aluminum sheet plate applied to marine shipbuilding. The integrated properties of 5083 aluminium best fits the raw material requirements for marine vessels, cruises, yachts, liners and even submarines in the ocean. 5083 h116 aluminium plate, 5083h111 aluminum plate, 5083h1121 aluminum and 5083 h321 aluminum plate are the most popular products for marine building. In addition, 5083 aluminum sheet plates are applied to tankers, cars, trains, fuel tanks, vehicle roofing and flooring etc.
