According to the market, the wheels can be divided into steel wheels and alloy wheels two categories, 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, the alloy wheel just can make up for such issues as light weight, low inertia resistance, high production precision and small deformation during high-speed rotation, which helps to improve the straight-running performance of the vehicle and reduce the rolling resistance of the tire. Reduce 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 mainly aluminum alloy, of course, many modified hub 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.
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 precision, high strength, low inertial resistance, strong heat dissipation and good visual effects. 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. Here we take a look at the three major characteristics of alloy wheels.
1 energy-saving: alloy wheels light weight, high precision, small deformation in high-speed rotation, inertial resistance is small, help to improve the car's linear driving performance, reduce tire rolling resistance, thereby reducing fuel consumption.
2 Safety: Aluminum alloy thermal conductivity is three times the steel, the cooling effect is very good, thereby enhancing the braking performance and improve the service life of the tire and brake disc, effectively protect the safe driving of the car.
Comfort: Equipped with alloy wheels are generally used cars with cushioning and shock absorption performance is better than ordinary flat tires, the car in the uneven road or high-speed driving, the comfort greatly improved.
