In general, aluminium sheet for boat factory in china adopt 5000 and  6000 series aluminum-magnesium alloys have excellent resistance to marine climate, especially seawater corrosion resistance has been recognized by everyone. 5083 aluminum alloy can be regarded as the representative product of 5000 series marine grade aluminum sheet for boat, and the tempers are O, H111, H112, H116, H321, etc., and is rated as used for the main shell structure best material due to the advantages of mechanical properties, corrosion resistance and cost.

Aluminum alloys supplied by aluminium sheet for boat factory in china have good seawater corrosion resistance, so they tend to use aluminum alloys with light weight and good welding performance. The good weldability of aluminum alloy means that the tendency of cracks formed during welding of aluminum alloy is smaller, that is, aluminum sheet for boat has good welding crack resistance, and the performance of the welded joint after welding does not change much. Aluminum work boats require less maintenance, use longer, and travel faster; no doubt, fishing boats or any other marine industry is necessary to make this kind of investment.

Marine aluminum alloys produced by aluminium sheet for boat factory in china generally choose weldable aluminum alloys with medium strength and corrosion resistance. In addition, cast aluminum alloys also have certain applications in the field of ships. The marine aluminum alloy matrix and welded joints are required to be free from stress corrosion, spalling corrosion and intergranular corrosion in seawater and marine environments. Contact corrosion, crevice corrosion and marine adhesion corrosion shall be avoided as much as possible. Less uniform corrosion and pitting corrosion are allowed.
