The wheels on the market can be divided into two categories: steel wheels and alloy wheels according to their materials, each of which has advantages and disadvantages.
The main advantages of steel wheels are simple manufacturing process, relatively low cost, and strong resistance to metal fatigue, which is what we commonly call cheap and strong. However, the disadvantages of steel wheels are relatively prominent. They are ugly in appearance (it can be said that there is no appearance at all), heavy (the same wheel steel material is much heavier than aluminum alloy material), inertial resistance is large, and heat dissipation is relatively poor. And it is very easy to rust.
Relatively speaking, alloy wheels can just make up for such problems. They have lighter weight, low inertial resistance, high manufacturing accuracy, and small deformation during high-speed rotation, which is conducive to improving the straight-line driving performance of the car and reducing the rolling resistance of the tires. Reduce fuel consumption. The thermal conductivity of the alloy material is about three times that of steel, and the heat dissipation is good, which can play a certain role in the thermal attenuation of the vehicle's braking system, tires and braking system. The alloy wheels of the original cars on the market are mainly made of aluminum alloy. Of course, many modified wheels will choose chromium, titanium and other elements as basic materials in order to meet certain special requirements and improve the vision. However, compared with steel wheels, the price of alloy wheels is much more expensive. Therefore, in many low-end and middle-end OEM cars, steel wheels will appear on low-profile models, while alloy wheels are high-profile. Standard equipment of the model.
