Method for discriminating aluminum alloy material

Recently, it has been reported that the market of aluminum alloy doors and windows is growing, and now many buildings use aluminum alloy doors and windows, so it has become necessary knowledge for consumers to learn to distinguish the quality of aluminum alloy materials. How to judge the quality of aluminum alloy doors and windows, whether it is aluminum alloy indoor doors (including partition doors) or aluminum alloy windows, decoration owners must pay attention to the following points when purchasing such products: Front: Materials for aluminum alloy doors and windows 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, which is not comprehensive. In fact, the state has certain standards for aluminum alloy doors and windows. The thickness, strength and oxide film of aluminum profiles used for high-quality aluminum alloy doors and windows can generally meet the national standards, such as the requirements of relevant national regulations: the wall thickness of aluminum profiles for aluminum alloy doors and windows should be not less than 1.2mm, and the oxide film thickness should reach 10 microns. Tempered glass is better than ordinary glass. Considering the safety and durability of doors and windows, stainless steel hardware fittings (such as screws, hinges, handles, etc.) are better than aluminum fittings, while pulley is better to choose POM products, because such products have higher strength and wear resistance, and are smooth and not easy to break during use. You know, damage to doors and windows usually starts with door and window accessories! Second: With good materials for processing, the next step is the processing of doors and windows. Because 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 installation workers, which requires operators to have good product quality awareness. It is very important to strengthen the operator's proficiency and product awareness in the production process. High-quality aluminum alloy doors and windows, with fine processing, smooth tangent and consistent angle (the main frame material is usually 45 degrees or 90 degrees), should not have obvious gaps in the splicing process, with good sealing performance and smooth opening and closing. Inferior aluminum alloy doors and windows, especially aluminum alloy outdoor window products, will have sealing problems if they are processed unqualified, not only leaking air and rain, but also the glass will burst and fall off under the action of strong wind and large external force, thus causing property losses and even injuries to the owners.

Why do people like to buy imported aluminum plates?

The reason why imported aluminum plate conquered people-ALCOA alloy material is irreplaceable in the industrial market;

1. compactness: the unique grain refinement process ensures that there are no Chacon trachoma, striations, bubbles, impurities, cracks and other undesirable phenomena.

2. Internal stress: Perfect pre-stretching (T651) process can completely eliminate internal stress, and it is not easy to warp, crack and deform during processing and stress.

3 Tolerance accuracy: All products meet the specifications of American Society of Materials and Experiments (ASTM) and Aerospace Materials (AMS).

4. Machinability: reduce the deviation of chemical composition, strength and hardness to Z, and prevent the occurrence of "knife sticking" and "knife collapse" during machining.

5. Uniformity: excellent heat treatment technology, the product is below 300MM thickness (or diameter), and the strength and hardness are basically the same.

6. Stability: All production processes are controlled by computer, with little human error, and different batches of Alcoa products can be provided to ensure basically the same performance.

7. Dyeing effect: even and shiny, with no stripes, spots or different colors on the surface.

8. Corrosion resistance Through microscopic examination of metals and alloys, it has excellent stress corrosion resistance and spalling corrosion resistance, and will not produce pits or blackening when used in various media (such as water vapor, weak acid and weak alkali, etc.) for a long time.

9. High temperature resistance: yong long-term deformation will not occur in the working environment of 400 degrees Celsius.
