The Marine Grade Aluminum 5083 and 5086
Aluminum alloy yachts for freshwater lakes are mostly made of 5052-H32 or 5052-0 aluminum plates, while luxury yachts on the sea are generally made of high-magnesium alloy 5083H116 or 5083H321 aluminum plates. Since they have undergone special processing technology, it has good corrosion resistance.
The tooling plate 5083 aluminum alloy belongs to the Al-Mg series high Mg aluminum alloy, which has good mechanical properties, machining properties and good corrosion resistance. It is mainly used to shipbuilding, transportation, and mold manufacturing. It is an important material for making molds, ship shells, fuel storage tanks, etc.
5083 aluminum plate has excellent strength, bending performance and seawater corrosion resistance. It is a kind of aluminum alloy for ships with good comprehensive performance. It can be used for the main structure and superstructure of ships. 5083H116/H321/H112 are commonly used.
5083 aluminum alloy’s self-corrosion potential fluctuates violently at the initial stage of immersion, showing a trend of decreasing first and then increasing, which is consistent with the change law of corrosion potential of high-entropy alloys. After 10 h, the self-corrosion potential gradually stabilized around -760 mV, with small fluctuations.
The self-corrosion potential of 5083 aluminum alloy in the stable corrosion stage is much higher than that of general aluminum alloy materials, and the higher self-corrosion potential reflects the good corrosion resistance of 5083 aluminum alloy in seawater system.
5086 aluminum sheet is another commonly used alloy for shipbuilding. Its magnesium content generally does not exceed 7%. With the increase of the magnesium content, the strength of the alloy will increase, and the plasticity will decrease.
5086 anti-rust aluminum sheet is usually used in the annealed state, cold hardened or semi-cold hardened state. Due to the effect of magnesium, the density of 5086 anti-rust aluminum plate is much higher than that of other aluminum plates, and it has very good corrosion resistance.
Generally speaking, the commonly used tempers of the marine grade aluminum 5086 are O, H111, H112, H116, H321, etc. In terms of mechanical properties, the tensile strength of 5086 aluminum sheet is ≧240, conditional yield strength is ≧95 and elongations is ≧10.
Haomei Aluminum not only has 5083 and 5086 aluminum plate, but also has 5383, 5059, 5754,etc. Welcome to leave message below to inquire what you need.
