Chemical composition and properties of 3003 aluminum alloy introduced

3003 for the AL-Mn series aluminum alloy, is the most widely used as a rust-proof aluminum, the strength of the aluminum alloy is not high (slightly higher than the aluminum industry) can not be heat strengthened, so the use of cold working methods to improve its Mechanical properties: in the annealed condition has a high plasticity, in the half-cold hardening plasticity is still good, when the plastic work hardening is low, good corrosion resistance, good weld ability, mach inability bad. Mainly used for high plasticity and good weld ability, working in a liquid or gaseous medium low load parts, such as fuel tanks, gasoline or oil conduit, with a variety of liquid containers and other small loads produced by deep drawing parts: 3003 aluminum wire used to make the rivet formability, welding properties, corrosion resistance were good. For processing need to have good formability, high corrosion resistance and good solder ability component parts, or both of these performance requirements and the need for higher intensity than the 1-series aluminum alloy work, such as kitchen utensils, food and chemical products processing and storage devices, tank transport of liquid products, cans, sheet metal processing to various pressure vessels and piping general objects, heat sinks, makeup board, photocopier rollers, ship timber.
