In terms of material, aluminum alloy has an excellent strength-to-weight ratio. Compared with other metals, it is light yet strong, which can easily support the opening and closing of doors and windows, while reducing the overall weight and facilitating installation and use. At the same time, aluminum alloy has strong natural corrosion resistance, which can resist water vapor and oxidation erosion, extend the service life of hinges, and reduce maintenance costs.
