1060 aluminum alloy ● Standard: GB/T3190-1996 ● Features and Scope: 1060 for adding a small amount of copper in aluminum by formation, has excellent molding processing characteristics, high corrosion resistance, good weldability and conductivity. 1060 is widely used in the intensity less demanding products, such as chemical instruments, pieces of sheet metal processing, deep drawing or spinning hollowware, welding parts, heat exchangers, bell surface and the disk, nameplates, kitchenware, decorations, reflective devices and so on. ● Chemical Composition: Iron (Fe) 0.03 0.35 Manganese (Mn) of magnesium (Mg) 0.03 silicon (Si) 0.25 Zinc (Zn) 0.05 titanium (Ti) 0.03 Copper (Cu) 0.5 ~ 0.6 of aluminum (Al) of 99.6 or more ● mechanical properties: Tensile strength σb (MPa) ≥ 75 Conditions yield strength σ0.2 (MPa) ≥ 35 Sample size: all wall thickness Note: longitudinal mechanical properties of the pipe room temperature ● Heat range: Rapid thermal annealing: heating temperature of 350 to 410 ° C; different with the effective thickness of the material, holding time 30 ~ 120min; air or water-cooled. High-temperature annealing: heating temperature of 350 ~ 500 ℃; the finished thickness ≥ 6mm, the holding time of 30min <6mm heat through so far; air cooling. Low temperature annealing: heating temperature of 150 to 250 ° C; the holding time for 2 ~~ h; .3003 air or water-cooled aluminum alloy ● Standard: GB/T3190-1996 ● Chemical Composition: Silicon Si: 0.60 Iron Fe: Zn Zn 0.70 Copper Cu :0.05-0 .20 Mn Mn :1.0-1 .5: 0 .. 10: single 0.05 Total 0.15 aluminum Al: margin ● Features and Applications: 3003 for the Department of AL-Mn alloy, is the most widely used as a rust-proof aluminum, the strength of this alloy is not high (slightly higher than the industrial aluminum), heat treatment can not be strengthened, so the use of cold working to improve its mechanical properties: in the annealed state has a high plasticity, and in the semi-cold hardening plastic is still good, low plasticity cold hardening, good corrosion resistance, good weldability, can machinability adverse. Uses mainly used require high plasticity and good weldability, low load part working in the liquid or gaseous medium, such as a mailbox, gasoline or oil conduit, a variety of liquid container and the other produced by deep drawing a small load Part: The wire used to make the rivet 3003 aluminum forming, welding, and corrosion resistance were good. For the processing of the need for good formability, high corrosion resistance, weldability good parts components, or enjoin these performance than 1XXX alloy high strength work, such as kitchen utensils, food and chemical products processing and storage device slot, tanks for the transport of liquid products, the general objects of the sheet processing all kinds of pressure vessels and pipes, heat sinks, make-up board, copier drum, ship timber. Mechanical Properties Tensile strength σb (MPa)) 142-178 Conditions yield strength σ0.2 (MPa)) ≥ 115 Sample size: all wall thickness Note: longitudinal mechanical properties of the pipe room temperature ● thermal processing and heat treatment temperature The homogenizing annealing temperature of 590 to 620 ° C, and the hot rolling temperature of 480 to 520 ° C, an extrusion temperature of 320 to 480 ° C, the typical annealing temperature is 413 ° C, and air-cooled. ● Performance Corrosion resistance: 3003 aluminum alloy corrosion resistance is very good, close to the corrosion resistance of commercially pure aluminum, the atmosphere, fresh water, sea water, food, organic acids, gasoline, neutral inorganic salt solution has good corrosion resistance acid corrosion resistance is also very good.   In the cold-deformed state, the 3003 aluminum alloy exfoliation corrosion tendency, the greater the deformation, peeling is more serious. Due to the color unevenness after the anodization, it is generally not be anodized. ● Aluminum state and Code Description Scope: This standard specifies the code of the state of deformation of aluminum alloy. This standard applies to aluminum and aluminum products. 2 basic principles  2.1 foundation status code with a capital letter.  2.2 subdivision status code foundation status code followed by one or more Arabic numerals.  2.3 Basic state code  Basic state is divided into five kinds Code Name Description and Application F free processing status applies to the molding process, no special requirements for work-hardening and heat treatment conditions, the mechanical properties of the products of the state are not provided. O annealed condition applies to the minimum strength of processed products obtained by the fully annealed. H hardening state suitable for improving the strength by work hardening in the work-hardened, the product may pass through the additional heat treatment (or not pass) so that the strength decreased. W solid solution heat treatment state processing state to an unstable state, applies only to the alloy after solution heat treatment, the natural aging at room temperature, the status code indicates that the product is only natural aging stage.
