Hardness: many customers are very concerned about when buying aluminum, hardness, chemical composition of alloys of choice with a direct relationship. Second, the various states have a greater impact, from the highest possible hardness of view, the 7 Series, 2 lines, 4 lines, 6 Series, 5 Series, 3 Series, 1 Series, in descending order. Strength: Strength is an important factor that must be considered in product design, as it is the aluminum alloy component as the component should be based on the pressure, select the appropriate alloy. Minimum strength aluminum, and 2 and 7 Series the highest heat-type alloy, hardness and strength of certain lower phase relationship. Corrosion resistance: corrosion resistance, including chemical corrosion, stress corrosion and other properties. In general, a system the best corrosion resistance of aluminum, 5 and performed well, followed by the 3 Series and 6 Series, 7 series 2 system and poor. Corrosion resistance selection should be based on the principle of the use of the occasion. High-strength alloy corrosion environments, you must use a variety of composite materials for corrosion protection. Processing of: processing performance package insert forming properties and cutting performance. Because with the state of formability, the choice of alloy grades, the need to consider the strength of the scope of the various states, usually forming high strength materials is not easy. If Taiwan were to be on the aluminum bending, stretching, deep drawing and other forming process, complete the forming of the annealed condition the best materials, on the contrary, the material forming heat treatment of the worst. Poor cutting aluminum alloy, for molds, machinery parts and other necessary cutting of better contrast, low intensity were poor machinability of the mold, cutting machine parts and other needed products, the cutting of aluminum is important considerations. Welding: aluminum welding majority had no problems, especially some 5 series aluminum alloy, it is designed for welding into account the relative surface of words, Part 2 and 7 Series aluminum welding more difficult. Decorative properties: aluminum used in decoration or certain other occasions, it needs to surface anodizing, painting and other processing, in order to obtain the corresponding color and surface structure, then the focus should be considered decorative, general and words, the better corrosion resistance material, anodizing, surface processing performance, painting and performance are excellent. Other features: In addition to the above characteristics, as well as electrical conductivity, wear resistance and heat resistance. In the selection can also be considered. Aluminum Usage: widely used in construction, packaging, air conditioning, cabinet enclosure cars, ships refrigerator solar reflector panels, mobile phone casing electrical equipment and cosmetics, but also used in power plants, chemical and petrochemical plants corrosion insulation,..... walls, caps, kitchen utensils, bags, watches and clocks, parts, metal stampings ,, lighting, signs, nameplates, gifts, metal cans, heat sinks, appliances panels, decorative building materials, transportation facilities, Mp3 cell phone case, elevators and car inside and outside decoration and other industries! International brands have already registered more than 1,000 aluminum, each grade there are a variety of European and American metal state, the hardness, strength, corrosion resistance, workability, welding, decorative, etc. There are obvious differences. When European companies Select grade aluminum and state, is difficult to satisfy both the above aspects, it is not necessary, should be based on performance requirements, the factors environment, processes, etc., to set priorities for various properties before make to a reasonable selection, performance guarantees before under the reasonable control costs.
