Aluminum alloy use range:
First, the application of strips is widely used in decoration, packaging, construction, transportation, electronics, aviation, aerospace, weapons and other industries.
Second, aerospace aluminum is used to make aircraft skins, fuselage frames, girders, rotors, propellers, fuel tanks, siding and landing gear props, as well as rocket forging rings, spacecraft siding, and so on.
Third, aluminum for transportation used in automobile, subway vehicles, railway passenger cars, high-speed passenger car body structure materials, doors and windows, shelves, automotive engine parts, air conditioners, radiators, body panels, wheels and warships timber.
Fourth, aluminum packaging aluminum cans canned materials mainly in the form of thin plates and foils as metal packaging materials, made of cans, caps, bottles, barrels, packaging foil. Widely used in beverages, food, cosmetics, pharmaceuticals, cigarettes, industrial products and other packaging.
Fifth, printing aluminum is mainly used for the production of PS version, aluminum-based PS version is a new type of printing industry materials for automated plate making and printing.
Sixth, aluminum for building decoration aluminum alloy because of its good corrosion resistance, sufficient strength, excellent technical performance and welding performance, are widely used in building structures, doors and windows, ceilings, decorative surfaces and so on. Such as all kinds of building doors and windows, curtain wall aluminum, aluminum curtain wall panels, pressure plate, pattern plate, color coated aluminum and so on.
Seven, aluminum for electronic appliances is mainly used for a variety of bus, wiring, conductors, electrical components, refrigerators, air conditioners, cables and so on.
There are more than 1,000 registered Aluminum Aluminium Awards in the world. Each brand has multiple states. There are significant differences in hardness, strength, corrosion resistance, processability, weldability, and decorativeness. When selecting the grades and states of aluminum alloys, the above aspects are difficult to meet at the same time, and it is not necessary. It is necessary to set the priorities of various properties according to the product performance requirements, the use environment, and the processing process, etc. The selection of materials is to control the cost reasonably before guaranteeing performance.
Hardness: Many customers are very concerned about buying aluminum. The hardness is preferably directly related to the chemical composition of the alloy. Secondly, different states also have a greater influence. From the higher hardness that can be achieved, the 7th, 2nd, 4th, 6th, 5th, 3rd, and 1th series decrease in turn.
Hardness: Strength is an important factor that must be considered when designing a product. When an aluminum alloy component is used as a component, an appropriate alloy should be selected according to the pressure applied. The strength of pure aluminum is lower, while the degree of heat-treated alloys of 2 and 7 series is higher, and the hardness and strength have a certain lower relationship.
Corrosion resistance: Corrosion resistance includes chemical corrosion, stress corrosion resistance and other properties. In general, the corrosion resistance of 1 series pure aluminum is better, 5 series performs well, followed by 3 series and 6 series, 2 series and 7 series are poor. Corrosion resistance selection principles should be based on the use of the occasion. For high-strength alloys used in corrosive environments, a variety of corrosion-resistant composite materials must be used.
Machinability: Processing performance, insert forming performance and cutting performance. Since the formability is related to the state, after selecting the aluminum alloy, the strength range of various states needs to be considered. Generally, a high-strength material is not easy to form. Forming and processing of aluminum should be carried out on aluminum materials such as bending, drawing, deep drawing, etc. The formability of the finished annealed material is better, whereas the formability of the material in the heat treated condition is poor. Aluminum alloys have poor machinability. For molds and mechanical parts, they need better machinability. Conversely, low-strength people have poor machinability. For products that require cutting, such as molds and mechanical parts, the machinability of aluminum alloys is important. Consider the factors.
Weldability: Most aluminum alloys have no problem in weldability, especially some 5 series aluminum alloys are designed specifically for welding considerations. Relatively speaking, some 2 Series and 7 Series aluminum alloys are harder to weld. Hangzhou Guangyue Metal Materials Co., Ltd.
Decoration performance: When aluminum is applied to decoration or certain specific occasions, it needs to be anodized, painted, etc. on its surface to obtain the corresponding color and surface texture. At this time, its decorativeness should be considered in the most important way. The material with good corrosion resistance has excellent anodizing performance, surface treatment performance and coating performance.
