When selecting aluminum alloy plates, the following aspects can be considered:
1. strength requirements: pulley disc is a kind of sports equipment, which needs to bear large impact and load. Therefore, choosing high-strength aluminum alloy plate can improve the sports performance and service life of skateboard.
2. Corrosion performance: the pulley plate is often used outdoors and is in contact with water and other environmental factors. Therefore, choosing aluminum alloy plate with good corrosion resistance can prolong the service life of skateboard.
3. Lightweight requirements: the pulley plate needs to perform various skillful actions when used, and the lighter material can improve the flexibility and reaction speed of operation. Choosing aluminum alloy material with lower specific gravity can reduce the weight of skateboard.
According to the above requirements, the commonly used aluminum alloy brands are 606 1, 7075, etc. Among them, 606 1 aluminum alloy has good weldability, corrosion resistance and machinability, and is often used as the plate material of pulley plate. 7075 aluminum alloy has high strength and wear resistance, and is often used as the bearing material of skateboard.
It should be noted that the material selection of pulley disc should also consider personal needs and budget, and can be selected according to specific circumstances. At the same time, it is also recommended to consult professional pulley disc manufacturers or equipment suppliers for more accurate advice.
