The 3003 aluminum alloy properties are complex. As an AL-Mn series alloy, 3003 contains a manganese alloy element, which greatly improves its rust prevention characteristics and make it the most widely used type of rust-proof aluminum alloy. The strength of this alloy is not high (slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment. Therefore, the cold working method is used to improve its mechanical properties. Manganese significantly increases the recrystallization temperature of aluminum and reduces the electrical conductivity of the alloy. If the conductivity of 1050A is taken as 100%, then the 3003 alloy is only 71% of 1050A, which is 40% IACS.
3003 aluminium alloy aluminum application covers uses of aluminium requiring high tensile strength, good welding property, low density and components that work in liquid or vapor substances, such as kitchen supplies, food materials and chemical raw materials. The various tanks, tanks, and various high-pressure vessels and pipes that are produced and processed by sheet metal are usually bronzes, radiators, color plates, photocopier drums, and ship materials.
The excellent corrosion resistance of 3003 aluminium alloy lies in the fact that it displays outstanding corrosion resistance to air, water, sea, food, citric acid, gasoline for vehicles, neutralized organic solutions, etc.
