China Die Casting Supplier introduces the selection method of aluminum alloy:
1. Materials used. The main materials generally include three aspects: aluminum profiles, glass, and hardware. When purchasing products, owners often pay more attention to the thickness of aluminum profiles and glass, but the requirements for hardware are not very high. Is not comprehensive. In fact, the country has certain standards for aluminum alloy doors and windows. Tempered glass is better than ordinary glass. If you consider the safety and durability of doors and windows, stainless steel hardware accessories (such as screws, hinges, handles, etc.) are better than aluminum accessories, and the pulleys are best to use POM products. , Because this kind of product has higher strength and abrasion resistance, it is smooth in use and not easy to break.
2. With good materials, the next step is the processing of doors and windows. The technical content of aluminum alloy doors and windows is not high, and the degree of mechanization is not high at present. Most of them still rely on the manual operation of the installation workers, which requires the operators to have a good product quality awareness. It is very important to strengthen the proficiency of operators and product awareness in the production process. High-quality aluminum alloy doors and windows have fine processing, smooth tangent lines and consistent angles (the main frame material is usually 45 degrees or 90 degrees), there should be no obvious gaps in the splicing process, good sealing performance, and smooth opening and closing.
3. Appearance. When purchasing aluminum alloy door and window products, owners usually pay attention to the appearance of the product and the decorative pattern of the glass, but often underestimate the composite film on the surface of the aluminum alloy door and window. This composite film is formed by the coloring of artificial oxide film and is resistant to Corrosion, wear resistance, high gloss, and also have a certain fire protection function, so you should compare similar products when choosing aluminum alloy doors and windows. The art of glasswork varies from person to person, and different owners choose according to their own preferences.
4. Price, because the price of aluminum alloy doors and windows is directly related to the price of aluminum ingots, but in general, the price of aluminum alloy doors and windows is relatively stable in a certain period of time. Guardian aluminum alloy forging claims that under normal circumstances, high quality The price of aluminum alloy is 30% higher than that of inferior aluminum alloy doors and windows. Inferior aluminum alloy doors and windows usually use aluminum extruded aluminum profiles that contain a lot of impurities. Some of the aluminum profiles used have a wall thickness of only 0.6-0.8 mm. Both the tensile strength and the yield degree are much lower than the relevant national regulations. This kind of aluminum alloy doors and windows, especially aluminum alloy outdoor windows, is very unsafe, so when buying products, owners must not look down on themselves and others because they are cheap. Personal safety.
5. Performance, the performance of aluminum alloy doors and windows is different due to the different scope of use, but usually the following aspects should be considered: strength, which is mainly reflected in the material selection of aluminum alloy doors and windows, whether it can withstand excess High pressure; air tightness, mainly reflected in the door and window structure, whether the inner fan and outer frame structure of the door and window are tight, whether the aluminum alloy outdoor window is tight and airtight; water tightness, mainly to check whether there is water and leakage in aluminum alloy doors and windows; Sound insulation, which mainly depends on the sound insulation effect of insulating glass and other extraordinary sound-proof airtight strip structure, as well as the durability of opening and closing force, heat insulation, nylon guide wheel durability, opening and closing durability and other door and window accessories.
Through the above introduction, Aluminum Die Casting Factory hopes that you can simply refer to the content of this article in future use.
