5000 and 6000 Marine Grade Aluminum Alloys
5000 series aluminum alloys used in marine engineering include 5052 (5A02), 5252, 5154, 5454, 5754, 5083, 5086, etc. The magnesium content of 5052 aluminum alloy is low; the magnesium content of 5154, 5454, and 5754 aluminum alloys is medium to low; the magnesium content of 5083 aluminum alloy is medium; the magnesium content of 5086 aluminum alloy is medium.
5086 aluminum sheet is an aluminum-magnesium alloy, mainly magnesium alloy. It is strengthened not by heat treatment, but by strain hardening or cold working of the material. Heat treatment does not significantly affect strength, so 5086 aluminum is easily weldable and retains much of its mechanical strength. 5086 h116 aluminum sheet is the recommended hull material for small aluminum boats and large yachts.
In addition, 5086 aluminum plates can also be used to manufacture chemical equipment, storage tanks, pressure vessels and other industrial equipment. In the chemical production process, many chemicals are highly corrosive. The corrosion resistance of 5086 aluminum plates can effectively protect equipment from corrosion.
Generally speaking, the commonly used tempers of 5086 marine aluminum plates are O, H111, H112, H116, H321, etc. In terms of mechanical properties, 5086 anti-rust aluminum plates have tensile strength over 240 Mpa, conditional yield strength over 95 Mpa and elongation is over 10.
6000 series aluminum alloys are a type of aluminum alloy composed of aluminum, magnesium and silicon. Its typical grades are 6061 and 6063, which are commonly used in aerospace, shipbuilding, automobiles, construction, electronics and other fields. 6000 marine aluminum alloys have excellent mechanical properties, corrosion resistance and processability, and are one of the most widely used aluminum alloys at present.
6063 is an aluminum magnesium silicon (Al-Mg-Si) aluminum alloy material. The magnesium content is between 0.45-0.9% and the silicon content is between 0.2-0.6%. Although the alloy content is very small, it greatly changes the properties of aluminum. Silicon increases the hardness of aluminum alloys, and magnesium increases the corrosion resistance of aluminum alloys.
6063 aluminum weldability is excellent. It uses tungsten inert gas welding. Typically, after welding, the properties near the weld are those of 6063-O, with a strength loss of up to 30%. The material can be reheat treated to restore the entire part to a higher temper. 6063 aluminum has excellent corrosion resistance. If it is surface treated, its anti-oxidation ability can be maximized. It can be used in harsh outdoor environments for more than 25 years.
