More and more automobile owners prefer aluminium alloy wheel hub for its appearance, comfort and safety. At present almost all the new types use aluminium alloy wheel hubs. And there are more owners who changed their old type wheel hubs to aluminium hubs.
The basic material of aluminium hubs is aluminium, certain amount of manganese, magnesium, chromium and titanium were added. Compared to steel hubs, aluminium hubs are safer, more comfortable and more energy-efficient. Thus more and more automobiles take aluminium alloy hubs as standard configuration.
Three main characters of aluminium alloy hubs:
Energy-efficient
Aluminium alloy hub is lighter and the accuracy of manufacturing is high. There is a small possibility that the hub will be out of shape when it is spinning with a high speed. The inertial resistance is small. These factors will reduce the rolling resistance of the wheels and make cars become energy-efficient.
Safty
The coefficient of heat conductivity of aluminium alloy is three time of steel, which makes a perfect heat dissipation effect. When the brake performance is increased, the life of wheels and disc brake will be extended. The safety of cars will be improved.
Comfort
Automobiles with aluminium hubs usually use wheels with better buffer performance than normal wheels. The better wheels make it comfortable to drive on a bumpy road in high speed.
