[China Aluminum Industry Network] What aluminum should be paid attention to when manufacturing aluminum alloy doors and windows:
A look at the materials. High-quality aluminum alloy doors and windows used in aluminum, thickness, strength and oxide film, shall comply with relevant national standards, the wall thickness should be 1.2 mm or more, tensile strength of 157 newtons per square meter mm, yield strength to achieve each Square millimeters 108 Newtons, oxide film thickness should reach 10 microns. If it fails to meet the above criteria, inferior aluminum alloy doors and windows cannot be used.
Second, see processing. High-quality aluminum alloy doors and windows, fine processing, installation stress, good sealing performance, switch freely. Inferior quality aluminum alloy doors and windows, blind selection of aluminum series and specifications, rough machining, saw cutting instead of milling, not installed as required, poor sealing performance, uncomfortable switching, not only air leakage and glass burst, but also To strong winds and external forces, it is easy to scrape or fall off the push-pull part or glass, destroying things and hurting people.
Three to see the price. Under normal circumstances, high-quality aluminum alloy doors and windows due to high production costs, the price is about 30% higher than inferior aluminum alloy doors and windows. Some aluminum alloy doors and windows made of aluminum materials with a wall thickness of only 0.6-0.8 mm have significantly lower tensile strength and yield strength than the relevant national standards and are not safe to use.
