Commonly used shaft materials for elevators include copper alloy shaft, stainless steel shaft, carbon steel shaft, and aluminum alloy shaft.Copper alloy shaft, mainly composed of copper, zinc, tin and other metal elements. The advantages are wear resistance, corrosion resistance, good thermal conductivity, and it is not easy to generate heat when rotating at high speed. However, the price is relatively high and processing is difficult.Stainless steel shaft is a shaft material with excellent corrosion resistance, which can adapt to harsh working environments such as high humidity, high temperature and high corrosion. At the same time, it has high hardness, good toughness and light weight, and can withstand large loads. The disadvantage is the higher price.Carbon steel shaft is a universal shaft material, relatively low price, good processing performance. However, the corrosion resistance and wear resistance of carbon steel shaft are worse than that of copper alloy shaft and stainless st…
