Difference between steel hub and aluminum hub and maintenance method

December 03, 2022

In fact, aluminum hub actually contains other metals, such as iron, so it should be called aluminum alloy wheels.
Compared with common aluminum USB Hubs, ordinary steel hubs have good toughness and poor hardness. Aluminum hubs, on the contrary, have good hardness but poor toughness. Therefore, the driver will find that after the potholes on the road, the steel hub does not change, and it will start to shake at a speed close to 100km/hr. Because it is stamped and the contour and mass weight are not accurate, it is inevitable. Causes unbalanced moment of inertia and jitter.
Aluminum hubs generally do not have high-speed jitter phenomenon. Steel hub: In order to strengthen the brake system heat dissipation, leaving a lot of cooling holes, while weakening the strength of the steel hub, making the anti-deformation ability worse when impacted. But the low cost of stamping production is its main advantage, with more steel hubs on the basic models.
Aluminum hub: aluminum hub generally does not have high-speed driving jitter phenomenon, because it is casting molding, the need to detect internal holes, and hair outside the turning machining, contour and mass accuracy is higher, the results of the rotation balance is better than the steel hub. Moreover, the aluminum hub has a light weight and can be made thicker than the steel hub, and also has a bonus effect on the acceleration performance of the vehicle.
Regardless of whether the hub or aluminum hub, should be regularly checked for damage.
In addition, the heat dissipation capacity of the aluminum alloy is better than that of the steel hub, and it also adds bonus to the braking performance. After a long journey, the tire wheel should be cleaned and maintained. Whether it is a steel hub or an aluminum hub, it is necessary to regularly check whether there is deformation and damage, and whether it needs to be replaced. Otherwise, it may cause problems such as brake delay and abnormal tire wear. Safety.
