Aluminum doors and windows are common products in our daily life. Aluminum alloy door and window profiles are the basic material for making aluminum alloy doors and windows, and are the main body of aluminum doors and windows. The size, precision grade, chemical composition, mechanical properties and surface quality of aluminum door and window profiles have an important impact on the production quality, service performance and service life of aluminum doors and windows.
Aluminum doors and windows are made of aluminum-magnesium-silicon-based aluminum alloy profiles, whose chemical composition includes silicon, iron, copper, magnesium, manganese, chromium, titanium, zinc and other alloy components in addition to aluminum. Which contains 0.45-0.90% magnesium and 0.2-0.6% silicon. The mechanical properties of aluminum door and window profiles: the tensile strength бb is not less than 157N/mm2; the specified non-proportional elongation stress бp0.2 is not less than 108N/mm2; the elongation is not less than 8%; the hardness HV is not less than 58.
