Automobile hub material can be divided into steel hub and alloy hub, among which the cost of steel hub is low and the quality is very good. But its disadvantage is heavy, and the steel hub shape is ugly, now many people buy cars are not very likely to choose steel hub.

　　Compared with steel hub, aluminum alloy hub has a great reduction in weight. It is important that aluminum alloy hub has good heat dissipation, more oil saving and more beautiful shape. However, aluminum alloy hub is also relatively high in manufacturing process. It can make different types of hub through different manufacturing processes, and it is also relatively expensive.

　　Whether it is aluminum alloy hub or steel hub, each automobile hub has its own parameters, so we must make sure to determine these parameters when purchasing. Especially when increasing the wheel hub, it is very important after all.
