Quality aluminum alloy material identification methods

First: the use of materials

Aluminum windows and doors main timber generally include three aspects: aluminum, glass, metal pieces, the owners buy products, they often pay more attention to the thickness of aluminum and glass, while the hardware requirements are not very high, it is not comprehensive. In fact, the state requirements for aluminum windows and doors there is a certain standard. High-quality aluminum alloy doors and windows used, its thickness, strength, and the oxide film can generally in line with national standards, such as relevant state requirements: aluminum windows and doors Aluminum Alloys wall thickness shall be not less than 1.2mm, the oxide film thickness of 10 microns. The tempered glass is better than ordinary glass, doors and windows if to consider safety and durability, stainless steel metal parts (such as screws, hinges, handles, etc.) than the aluminum parts is good, but the best choice pulley products using POM material because such products have higher strength and wear resistance, use the process smooth, non-perishable. You know, usually from doors and windows broken window fittings started yo!

Second: Processing

With good material, the next step is the processing of the doors and windows. Because aluminum windows and doors the technical content is not high, the current is not high degree of mechanization, the majority of workers are also dependent on the installation manual, which requires operators to have a good awareness of product quality. In the production process to enhance the operator's proficiency and product awareness is very important. High-quality aluminum windows and doors, fine processing, tangent smooth, consistent angle (main frame material under normal circumstances is 45 degrees or 90 degrees), in the splicing process should not appear obvious gap, good sealing performance, switching smoothly. Poor quality aluminum windows and doors, especially if machining aluminum outdoor window products fail, there will be sealed nature of problems, not only leakage leaking, but also in the strong winds and large external force, the glass will be burst, shedding phenomenon, giving cause losses of property owners and even wounding phenomenon.

Third: Appearance

Owners buy aluminum doors and windows products, usually very focused on the product's appearance and glass decorative patterns, but often underestimate the surface of aluminum windows and doors composite membrane, the composite membrane is an artificial coloring oxide film formation, corrosion resistant, wear-resistant loss, high gloss, but also has a certain fire safety features, so buy more aluminum doors and windows products should compare similar products. Art on the glaziers varies with different owners to choose according to their preferences.

Fourth: Price

Since the level of prices and aluminum windows and doors aluminum price level has a direct correlation, but in general the performance of aluminum windows and doors in a given period the price is relatively stable, in general, than the price of inferior quality aluminum alloy 30% higher windows and doors, aluminum windows and doors usually inferior contains a lot of impurities in recycled aluminum extruded aluminum, the use of aluminum and some only 0.6-0.8 mm wall thickness, either from the tensile strength or yield degrees are greatly below the national regulations, such aluminum alloy doors and windows, especially aluminum outdoor window is very safe, so the owners do not buy products cheaper and despise momentary own personal safety and that of others.
