In fact, the aluminum hub actually contains other metals, such as iron, so it should be called aluminum alloy wheels. Gubot is one of the supplier manufacturer the car wheel rim repair cnc lathe machine ,machine repair the aluminum alloy wheels.
Compared with ordinary aluminum hubs, ordinary steel hubs have good toughness and poor hardness, while aluminum hubs have the opposite hardness and good toughness. Therefore, the driver will find that after the potholes on the road, the steel hub does not change, and will start to shake at a speed close to 100km/hr. Because it is stamped, the contour and mass weight are not accurate. Shaking the inertia of the moment of inertia
Aluminum hub generally has no high-speed running jitter
Steel hub: In order to strengthen the heat dissipation of the brake system, there are many heat dissipation holes, and at the same time, the strength of the steel hub is weakened, so that the resistance to deformation is deteriorated when subjected to impact. However, the low cost of stamping production is its main advantage, and it is equipped with steel hubs on the basic models.
Aluminum hub: Aluminum hub generally has no high-speed running jitter phenomenon. Because it is cast and molded, it needs to detect internal voids and external blank turning. The contour and mass accuracy are higher. As a result, the turning balance is better than the steel hub. Moreover, the aluminum hub is light in weight and can be made thicker than the steel hub, and it also has a plus effect on the acceleration performance of the vehicle.
Whether it is a steel hub or an aluminum hub, it should be checked regularly for damage.
In addition, the heat dissipation capacity of the aluminum alloy is better than that of the steel hub, and the brake performance is also added. After long journeys, the tire hub should be cleaned and maintained. Whether it is a steel hub or an aluminum hub, it should be checked regularly for damage and whether it needs to be replaced. Otherwise, it may cause problems such as slow brakes and abnormal loss of the tires, which may affect the driving, Safety.
