If you mind, please think twice before placing an order with perfectionists;The product is made of zinc alloy in one piece. The die-cast zinc alloy has good mechanical properties at room temperature. However, the tensile strength at high temperature and the impact performance at low temperature are significantly reduced. It is not suitable for use in high temperature and low temperature (below 0??) working environments. Note: Please pay attention to the maintenance of metal products. It is easy to cause rust in high salt, high alkali, and high acidity environments. Please wipe off the sweat on the surface for long-term storage. If necessary, you can apply a layer of motor oil on the surface to form an oil film to isolate air oxidation.
