Marine Grade Certified Plate 5052

5052 aluminum plate is a typical 5000 series aluminum sheet, featuring good tensile strength, fatigue strength and excellent corrosion resistance, especially high resistance to salt spray corrosion in marine environments. 5052 aluminum hardness is about 12H in Webster system and 120-160HB in Brinell system.

In the international code, 5052 aluminum plate can also be called almg2.5, which also means that the content of mg alloy (magnesium alloy) is around 2.5% (between 2.2-2.6), with low density (2.68), high strength, and strong machinability. It is an excellent product suitable for bending, stamping, stretching and other processing techniques.

The role of chromium in 5052 aluminum plates is similar to that of manganese. It improves resistance to stress corrosion cracking, increases the strength of the base metal and welds, and reduces the tendency of welding cracks, but its content generally does not exceed 0.35%.

5052 h32 is an annealing process that accounts for a large proportion of the entire use. This annealing temperature is generally direct annealing at 420- 475℃. It has the advantages of high temperature resistance, corrosion resistance, and oxidation resistance.

At present, many fishing boats and yachts of similar size currently on the market use 5052 alloy. Aluminum alloy yachts and park boats for freshwater lakes are mostly made of 5052-H32 or 5052-0 aluminum plates. The thickness of the aluminum plate used is determined by the hull structure, ship specifications and usage parts. From the perspective of lightweighting the hull, a ship should use thin plates as much as possible, but the depth of corrosion of the plate during the use time should also be considered.

Haomei Aluminum supplies marine grade certified plates including 5052, 5083, 5086,etc. They have been certified by China Classification Society (CCS), Det Norske Veritas (DNV), American Bureau of Shipping (ABS), Bureau Veritas (BV), and British Company (LR). And they have entered the world shipbuilding market and was loved by the Philippines, Myanmar, Vietnam, Thailand, Indonesia and other Southeast Asian and North American shipbuilding markets.
