Are: steel wheels, alloy wheels.
The original wheel on the market in accordance with the material can be divided into steel wheels and alloy wheels, both have their own advantages and disadvantages.
The main advantage of steel wheels is the manufacturing process is simple, the cost is relatively low, but also a strong ability to resist metal fatigue, which is commonly known as cheap and strong. However, the disadvantages of steel hubs are relatively ugly appearance (no appearance can be said at all), the weight of the larger (the same wheel steel material much heavier than the aluminum alloy material), inertial resistance, heat dissipation is relatively poor, And very easy to rust.
Relatively speaking, alloy wheels can just make up for such problems as light weight, low inertial resistance, high production precision, small deformation when rotating at high speed and small inertial resistance, which are beneficial to improve the straight running performance of the vehicle and reduce the linearity Tire rolling resistance, thereby reducing fuel consumption. Alloy thermal conductivity of steel is about three times, good heat dissipation, for the vehicle's braking system, tire and brake system thermal attenuation can play a role. The original car alloy wheels on the market are aluminum alloy, of course, many modified wheels in order to achieve certain special requirements and visual upgrade will choose chromium, titanium and other elements as the basic material. However, compared with the steel wheel hub, the alloy wheel prices are much more expensive, so often in many low-end level of the original car, the steel wheels will appear in the low with models, and alloy wheels are high with Standard models.
1.The main advantages of a steel hub is the manufacturing process is simple, the cost is relatively low, anti-metal fatigue ability. But the disadvantages are also obvious, such as weight, inertial resistance, poor heat dissipation and so on.
2.Alloy wheel has the advantages of light weight, high manufacturing precision, high strength, low inertial resistance, strong heat dissipation, good visual effect, etc. The disadvantage is that the manufacturing process is complicated and the cost is high.
Alloy wheels and more aluminum as the basic material, appropriate by adding manganese, magnesium, chromium, titanium and other metal elements made. Compared with the steel wheels, the alloy wheels are energy saving, safe and comfortable. Therefore, more and more cars have listed the alloy wheels as standard.
