Wheels on the market according to the material can be divided into steel wheels and alloy wheels, and each has its own advantages and disadvantages.

Automotive display steel wheel hub is the main advantage of the manufacturing process is simple (generally using the casting process, such as aluminum alloy wheels are generally produced using a low-pressure casting process) relatively low cost, and resistance to metal fatigue is very strong, that is, we are commonly known as cheap and sturdy. But the shortcomings of the steel wheel is also relatively prominent is the ugly appearance (it can be said that there is no appearance to speak of), the weight is greater (the same wheel steel than aluminum alloy material is much heavier), inertia resistance, heat dissipation is also relatively poor, and very easy to rust. Alloy wheel can make up for such problems, lighter weight, inertia resistance, high production precision, small deformation in high-speed rotation, inertia resistance is small, conducive to improving the car's straight-line driving performance, reduce tire rolling resistance, thereby reducing fuel consumption. The thermal conductivity of the alloy material and is about three times that of steel, good heat dissipation, for the vehicle's braking system, tires and braking system heat attenuation can play a role. Alloy wheels of the original car on the market are mainly aluminum alloy, of course, many modified wheels in order to achieve certain special requirements as well as visual enhancement will choose chrome, titanium and other elements as the basic material. However, compared with steel wheels, alloy wheels are much more expensive, so often in many low-end level of the original car, steel wheels will appear in the lower models, while the alloy wheels are the standard equipment of the higher models.
