Aluminum alloy standards
Main features and application scope: It is a series of alloys and is the most widely used anti-rust aluminum. This The strength of this alloy is not high (slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment, so cold working method is used to improve its mechanical properties: it has high plasticity in the annealed state, and the plasticity is still good during semi-cold work hardening. When hardened, it has low plasticity, good corrosion resistance, good weldability, and poor machinability. It is mainly used for low-load parts that require high plasticity and good weldability, and work in liquid or gas media, such as oil tanks, gasoline or lubrication Oil conduits, various liquid containers and other small-load parts made of deep drawing: wires are used to make rivets
Buyer's instructions
1: Hardness: Many customers are very concerned about when buying aluminum, and the hardness is the first choice. The chemical composition of the alloy is directly related. Secondly, different states also have a greater impact. From the perspective of the highest hardness that can be achieved, system, system, system, system, system, system, system, decrease in order.
2 ：Strength: Strength is an important factor that must be considered in product design. When aluminum alloy components are used as components, the appropriate alloy should be selected according to the pressure it bears. Pure aluminum has the lowest strength, while heat-treated alloys have the highest degree of alloying. , hardness and strength have a certain lower phase relationship.
Three: Corrosion resistance: Corrosion resistance includes chemical corrosion, stress corrosion resistance and other properties. Generally speaking, pure aluminum has the best corrosion resistance, and its performance Good, followed by series and series, series and series are poor. The selection principle of corrosion resistance should be based on the occasion of use. When high-strength alloys are used in corrosive environments, various anti-corrosion composite materials must be used.
Four : Processability: Processing performance includes formability and cutting performance. Because formability is related to the state, after selecting an aluminum alloy grade, you also need to consider the strength range of various states. Generally, materials with high strength are not easy to form. Taiguo needs to be careful When aluminum materials are subjected to bending, drawing, deep drawing and other forming processes, the formability of the material in the fully annealed state is the best. On the contrary, the formability of the material in the heat-treated state is the worst. The machinability of aluminum alloy is poor, and it is not suitable for molds, mechanical parts, etc. It needs to have better machinability. On the contrary, those with low strength have poor machinability. For products that require cutting such as molds and mechanical parts, the machinability of aluminum alloys is an important consideration.
Five: Weldability: Most aluminum There is no problem with the weldability of the alloys, especially some series of aluminum alloys, which are specially designed for welding considerations. On the other hand, some series and series of aluminum alloys are more difficult to weld.
6: Decorative performance: When aluminum is used for decoration or certain specific occasions, its surface needs to be anodized, painted, etc. to obtain the corresponding color and surface structure. At this time, its decorative properties should be The important thing to consider is that generally speaking, materials with good corrosion resistance have excellent anodizing performance, surface treatment performance, and coating performance.
Seven: Other characteristics: In addition to the above characteristics, there are also conductivity, wear resistance, heat resistance, etc. It can also be considered when selecting materials.
Eight: Aluminum alloy uses: Products are widely used in construction, packaging, air conditioners, chassis and cabinet casings, automobiles, ships, refrigerators, solar reflectors, mobile phone casings, mechanical and electrical equipment, cosmetics, etc., and can also be used in power plants, Chemical and petrochemical plant anti-corrosion insulation, curtain walls, bottle caps, kitchen utensils, bags, watch accessories, hardware stamping parts, lighting, signs, nameplates, craft gifts, hardware can making, heat sinks, household appliance panels, decorative building materials, transportation facilities, mobile phones Shell, elevator and automobile interior and exterior decoration and other industries.
