Why produce bushing with copper alloy?
In addition to pure copper, copper can be metallized with tin, zinc, nickel and other alloys with different characteristics, namely bronze, brass and white copper. By adding zinc in pure copper (99.99%), it is called brass, such as 80% of copper and 20% of zinc, used in a condenser and car radiator in a power plant; the rest is called bronze, and the rest is called bronze. Besides zinc and nickel, the copper alloys that are added to other metal elements are called bronze. The elements are called elements. The most important bronze is Tin Phosphorus Bronze and beryllium bronze. For example, tin bronze has a long history in China. It is used for casting clocks, tripod, musical instruments and sacrificial utensils. Tin bronze can also be used as bearings, bushings and wear-resistant parts.
