Selection method of high quality aluminum alloy

Do you know how to choose a high-quality aluminum alloy or aluminium track profiles?Here Goldapple-aluminium profile manufacturer will share the methods with you.

First, the materials.

The main materials for aluminum profiles and doors generally include three aspects: aluminum profiles, glass, hardware. When the owner purchases products, they tend to pay more attention to the thickness of aluminum profiles and glass, but the requirements for hardware are not very high. comprehensive. In fact, the national requirements for aluminum alloy doors and windows are certain. The aluminum profiles used for high-quality aluminum alloy doors and windows, the thickness, strength and oxide film can generally meet the national standards, such as the relevant national requirements: aluminum framing systems, like aluminum alloy doors and windows aluminum profile wall thickness, should be no less than 1.2mm, oxide film The thickness should be 10 microns. While tempered glass is better than ordinary glass, if the safety and durability of doors and windows can be considered, stainless steel hardware accessories (such as screws, hinges, handles, etc.) are better than aluminum fittings, and pulleys are best to use POM products. Because these products have higher strength and wear resistance, they are smooth and not easily damaged during use.

Second, processing methods

With good materials, the next step is the processing of doors and windows. Due to the low technical content of aluminum alloy doors and windows, the degree of mechanization is currently not high, and most of them rely on the manual operation of the installation workers, which requires the operator to have a good sense of product quality. It is important to enhance the proficiency and product awareness of the operator during the production process. High-quality aluminum alloy doors and windows, fine processing, smooth tangent, uniform angle (the main frame material is usually 45 degrees or 90 degrees), there should be no obvious gap in the splicing process, the sealing performance is good, the switch is smooth. Inferior aluminum alloy doors and windows, especially aluminum alloy outdoor window products, if processed unqualified, there will be sealing problems, not only leakage of wind and rain, but also under the action of strong wind and large external force, the glass will burst and fall off, thus giving The owner caused damage to property and even injury.

Third, the appearance

The owner purchases aluminum alloy door and window products, usually pays attention to the appearance of the product and the decorative pattern of the glass and often scorns the composite film on the surface of the aluminum alloy door and window. The composite film is formed by the artificial oxide film coloring, which has corrosion resistance and wear resistance. Loss, high gloss, and also have a certain degree of fire protection, so when buying aluminum alloy doors and windows products, compare more similar products. In the art of glasswork, it varies from person to person, and different owners choose according to their own preferences.

Fourth, the price

Since the price of aluminum alloy doors and windows is directly related to the price of aluminum ingots, the price of aluminum alloy doors and windows is relatively stable in a certain period of time. Under normal circumstances, the price of a high-quality aluminum alloy is better than that of an inferior aluminum alloy. Door and window products should be 30% higher. Inferior aluminum alloy doors and windows usually use aluminum profiles extruded with recycled aluminum. The aluminum profiles used are only 0.6-0.8 mm thick, both in tensile strength and yield. Below the relevant national regulations, such aluminum alloy doors and windows, especially aluminum alloy outdoor windows are very unsafe, so the owners should not be cheap and scorn the personal safety of themselves and others when purchasing products.
