6082-T6 aluminum alloy 6082-T6 aluminum rod rod 6082-T6 aluminum

6082 introduction of aluminum 6082 belong 6 ××× series (Al-Mg-Si) aluminum alloy, is able to heat treatment can be enhanced aluminum alloy sheet, with moderate strength and good weldability, corrosion resistance, mainly used for transport and structural engineering industry. Such as bridges, cranes, roof trusses, transport, transport vessels. In recent years, with the rapid development of domestic and foreign shipbuilding industry to reduce the hull weight, increase speed of the ship, seeking to replace aluminum alloy steel parts, has become an important issue facing the aluminum industry and shipbuilding. 6082 aluminum alloy aluminum with moderate strength and good corrosion resistance, and light weight, is an ideal material for high-speed craft parts. Chemical composition of the aluminum plate silicon Si 6082: 0.7 to 1.3; iron Fe: 0.5; copper Cu: 0.10; Mn Mn: 0.4 ~ 1.0; magnesium Mg: 0.6 ~ 1.2; chromium Cr: 0.25; Zinc Zn: 0.20; Ti Ti: 0.10 ; aluminum AL: margin. Mechanical properties of tensile strength 6082 aluminum σb (MPa): ≥205 Conditions yield strength σ0.2 (MPa): ≥110 Elongation δ10 (%): ≥14 Note: Profiles room temperature mechanical properties of longitudinal sample size: all thicknesses Homogenization temperature: 555-565 ℃ holding time: 3 hours, the cooling rate ≥200 ℃ / h 6082 aluminum casting process 1, 6082 alloy is characterized by melting containing Mn, Mn is a refractory metal, melting temperature should be controlled at 740-760 ℃. Stir twice more before sampling to ensure that the metal is completely melted, the temperature accurately, uniform composition. After stirring in the middle of the depth of molten aluminum furnace from each of the left and right sides of a sample for analysis, after sub-fold converter can be qualified. 2, after purification and casting the melt into the holding furnace, with nitrogen and refining agent dusting, jet refining, refining temperature 735-745 ℃, time 15 minutes, after refining for 30 minutes. Through this process degassing, slag, clean melt. When cast in the mold to prescribe filtering device between the furnace mouth, mouth foam ceramic filter plate (30PPI) filter, before casting glass fiber cloth with 14 mesh filter, fully filtered melt oxide slag. 6082 alloy aluminum casting temperature is high (compared with 6063 aluminum normal process), casting speed is low, the water flow is too large, the above process should be strictly controlled, not out of range, otherwise easily lead to casting failures. Fifth, the relevant technical standards with national standards for aluminum (GB / T 3880-2006), apply to the unified standard aluminum strip material. Aluminum state and Symbol Description 1. Scope: This standard specifies the state of deformation of aluminum alloy code. This standard applies to aluminum and aluminum products. 2. Basic Principles 2.1 Basic state code with a capital letter. 2.2 Subdivision state code uses basic state code followed by one or more Arabic numerals. 2.3 Basic state code divided into five kinds of basic state Code Name Description and Application F free processing state applies in the molding process, hardening and heat treatment conditions for no special requirements for products, the mechanical properties of the state of the product is not specified. O annealed condition applies fully annealed to obtain a minimum strength of processed products. H hardening state applies through hardening to increase the strength of the product, the product may be subjected to after hardening (or not been) reduced the strength of the additional heat treatment. W solid solution heat treatment processing status of an unstable state, only apply to the solution heat treatment, the natural aging of the alloy at room temperature, the state code only that the product is natural aging stage. T heat treatment (unlike F, O, H state) applied to the heat-treated, after (or without) hardening to achieve a stable product. T code must be followed by one or more digits. In the first digit represents the back of the T heat treatment basic types (from 1 to 10), followed by the digits represent change in the heat treatment details. Such as the 6061-T 62; 5083-H 343 and so on. Surface treatment of aluminum alloy sheet aluminum surface treatment by non-paint products and paint can be divided into two major categories of products. 1) non-paint products (1) can be divided into aluminum hammer (irregular pattern), embossing plate (regular patterns) and pre-passivated aluminum surface processing board. (2) This item is not painted on the plate surface treatment, the surface appearance of the less demanding lower prices. 2) paint products (1) Category: Press the coating process can be divided into: Spray board products and pre-roll coating plate; can be divided according to the type of paint: polyester, polyurethane, polyamide, modified silicone, epoxy resins, fluorocarbon and the like. (2) a variety of coatings, the main performance difference is resistance to ultraviolet sunlight, which in front of the most commonly used coating is fluorocarbon (PVDF), its ability to resist strong ultraviolet
