The wheel hub is one of the important components in the vehicle running system and also a safety part with high requirements.
Steel automotive wheel hubs VS aluminum alloy die-cast automotive wheel hubs
Compared with steel automotive wheel hubs, aluminum alloy die-cast automotive wheel hubs have the following advantages:
Lightweight, with a weight reduction of 30% - 40% compared to steel wheel hubs. According to relevant information, for every 1% reduction in the vehicle's mass, its fuel consumption will decrease by 0.6% - 1%.
They have good shock absorption performance and strong impact energy absorption capacity, which can improve the vehicle's driving performance and enhance safety. T
Hey have good thermal conductivity, with a thermal conductivity approximately three times that of steel. This can reduce the working temperature of the tires and extend the tire's service life.
They have an aesthetically pleasing appearance. The structures of aluminum alloy die-cast wheel hubs produced by different processes can be diversified, which can well meet the aesthetic requirements of various users.
Forming methods for aluminum alloy die-cast wheel hubs
There are many forming methods for aluminum alloy die-cast wheel hubs, mainly divided into the casting method and the forging method.
Currently, low-pressure casting processes are mostly used to form aluminum wheel hubs for cars. To improve their performance, there is a trend of development towards squeeze casting (liquid forging) forming and semi-solid forging forming. Due to the advantages of the casting method for producing aluminum alloy die-cast wheel hubs, such as strong adaptability, diverse varieties, and relatively low production costs, the casting method remains the most common method for producing aluminum alloy die-cast wheel hubs.
At present, more than 80% of the aluminum alloy die-cast wheel hubs produced worldwide are cast.
