3003 aluminum coil information encyclopedia

Date: 2019-05-21 11:09
    The 3003 aluminum coil is a metal product for the flying shear after the casting mill has been subjected to calendering and drawing. Widely used in electronics, packaging, construction, machinery and other industries.
Chemical Composition Limits wt%: Cu 0.05-0.2 Si 0.6 Fe 0.7 Mn 1.0-1.5 Mg / Zn 0.1 Cr / Ti / Pb. Bi / Al balance

    3003 aluminum coil is AL-Mn alloy, which is the most widely used rust-proof aluminum. The strength of this alloy is not high (slightly higher than industrial pure aluminum), and it can not be heat-treated and strengthened. Therefore, cold working method is used to improve its mechanics. Performance: It has high plasticity in the annealed state, good plasticity in semi-cold hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability and poor machinability. Applications are mainly for low-load parts that require high plasticity and good weldability, working in liquid or gaseous media, such as mailboxes, gasoline or lube conduits, various liquid containers and other small load parts made with deep drawing: The wire is used to make rivets.
Mechanical properties: tensile strength σb (MPa) ) 140-180, conditional yield strength σ0.2 (MPa) ) ≥ 115, sample size: all wall thickness, in addition to the longitudinal mechanical properties of the pipe at room temperature.
    The strength of 3003 aluminum coil rust-proof aluminum is about 10% higher than that of 1100, and the formability, the weldability and the corrosion resistance are good. Used to process parts that require good formability, high corrosion resistance, or require both these properties and work with higher strength than 1XXX alloys, such as kitchenware, food, and chemical processing. Storage device, tanks and tanks for transporting liquid products, various pressure vessels and pipes for processing with thin plates, general fins, heat sinks, cosmetic plates, photocopier drums, marine materials.
    The alloying element of 3003 aluminum coil is manganese, which has excellent forming processing characteristics, high corrosion resistance, good weldability and electrical conductivity, and the strength is higher than 1100. It is widely used in kitchen utensils, food and chemical product processing and storage devices, tanks and tanks for transporting liquid products, various pressure vessels and pipes processed by thin plates, heat exchangers, rivets, welding wires, washing machine cylinders, etc.
