The durability evaluation of aluminum alloy handles can be considered from multiple aspects, and the following are some main evaluation criteria and methods: 1、 Material quality Material selection: High quality aluminum alloy handles are usually made of high-quality aluminum alloy materials, such as 6063 or 5052. These materials have good corrosion resistance and strength, which are the foundation for ensuring the durability of the handle. Chemical composition analysis: Through chemical composition analysis, the content of various elements in aluminum alloy materials can be understood, thereby determining whether the material is pure and whether it has good physical and chemical properties. 2、 Surface treatment Processing technology: Observe whether the surface treatment of the aluminum alloy handle is smooth and uniform, without obvious scratches, pits or protrusions. High quality surface treatment, such as anodizing treatment, should have uniform color, no spots or color differences, and strong coating adhesion that is not easily peeled off. Corrosion resistance: Evaluate the corrosion resistance of the handle surface through testing under simulated harsh environmental conditions, such as salt spray testing. After long-term use, high-quality aluminum alloy handle should not show signs of oxidation or corrosion and maintain a good appearance. 3、 Structural sta
