[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model enhances the hardness of the aluminum alloy substrate layer by setting a reinforcing layer. It features light weight, low density, good heat dissipation, strong compressive strength, and good corrosion resistance, thereby enhancing the strength and hardness of the aluminum alloy substrate layer.

[0024] The usage process of this utility model is as follows: When using this utility model, the aluminum-magnesium alloy layer 61 is set to enhance the hardness of the aluminum alloy substrate layer 5, which has the characteristics of being lightweight, having low density, good heat dissipation, strong compressive strength, and good corrosion resistance, thereby enhancing the strength and hardness of the aluminum alloy substrate layer 5. The aluminum-zinc alloy layer 62 is set, and by adjusting the zinc content, the corrosion resistance and other mechanical properties of the aluminum alloy can be improved, thereby increasing the corrosion resistance of the aluminum alloy substrate layer 5.

[0025] Example 2: This utility model provides a novel bottom-hook type door and window handle, which differs from Example 1 in that:

[0026] Refer to the instruction manual appendix Figure 1-6 In this embodiment, a novel bottom-hook door and window handle is provided. The outer surface of the aluminum-magnesium alloy layer 61 is bonded to the inner surface of the aluminum-zinc alloy layer 62. The outer surface of the electroplated layer 71 is bonded to the inner surface of the nano-coating layer 72. The outer surface of the nano-coating layer 72 is bonded to the inner surface of the fluorocarbon paint layer 73. The material of the handle mounting frame 3 is the same as that of the face plate 4.

This enhances the strength and hardness of the aluminum alloy substrate layer 5. The aluminum-zinc alloy layer 62, by adjusting the zinc content, improves the corrosion resistance and other mechanical properties of the aluminum alloy, increasing the corrosion resistance of the aluminum alloy substrate layer 5. The fluorocarbon paint layer 73, a highly weather-resistant coating, forms a thin and hard protective film on the aluminum alloy surface after spraying, exhibiting excellent corrosion resistance and weather resistance, enabling long-term use in harsh natural environments and increasing the corrosion resistance of the aluminum alloy substrate layer 5. The electroplating layer 71 forms a high-hardness metal layer on the aluminum alloy surface, significantly improving its wear resistance and corrosion resistance.
