    The aluminum profiles for doors and windows are made of 6-series aluminum alloy, and the aluminum-magnesium silicon is the main element of the 6-series aluminum alloy, and each element has a certain range of content. However, the price of various elements is inconsistent, and the lack of precious metal content is a major cause of poor profile quality. Only in strict proportion then can produce aluminum extrusions of excellent quality. The prepared raw materials are placed in an aluminum melting furnace to be melted, slag is discharged, cooled, and then cast aluminum ingots or bars are used for the production of aluminium profiles. If the exhaust is not ideal, the air bubbles in the aluminium profile will cause defects. The aluminium profiles for doors and windows are mainly made of 6063 grade aluminum alloy. If the aluminum extrusion manufacturer uses the national standard 6063 aluminum ingot, it will be guaranteed in terms of raw material quality.

    3. The color is clean and beautiful: the frame material of the aluminum profile of doors and windows is treated with ammoniated coloring, and has silver-white, bronze, dark red, and other colors, and has a color pattern. The aluminum alloy doors and windows thus have a beautiful appearance, a clean surface, and bright and firm colors, which improve the decorative effect of indoor and outdoor facades. Thermal insulation in aluminum profiles for doors and windows, refractory waterproof corrosion sound insulation, and other properties are wooden windows. Steel windows, with their moderate price, luxurious appearance, diverse styles, good sealing, fire and flame retardant, difficulty in deforming, good strength, easy installation, and exquisite workmanship, are a new generation of door and window materials with broad prospects.
