The wheel rim is a barrel-shaped metal part with the center mounted on the shaft that supports the tire on the inner profile of the tire; it is also called a wheel rim, a steel ring, a wheel, and a tire bell.
The wheels on the market can be divided into steel wheels and alloy wheels according to their materials, and each has its own advantages and disadvantages.
01Which is better, steel wheel or aluminum alloy wheel?-steel wheel
The main advantage of steel wheels is the simple manufacturing process (generally using casting process, for example, aluminum alloy wheels are generally produced by low-pressure casting process), the cost is relatively low, and the ability to resist metal fatigue is very strong, which is what we commonly call cheap and solid.
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.

Alloy wheel rims can just make up for such problems. They are lighter in weight, low inertial resistance, high in manufacturing accuracy, small in deformation during high-speed rotation, and low inertial resistance, which is beneficial to improve the straight-line driving performance of the car and reduce the rolling resistance of the tires. Reduced 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.
Why do so many people choose alloy wheels but not steel wheels? Which is better, steel wheel and aluminum alloy wheel?
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. In today's automobile market, steel wheels are rare, and most models use aluminum alloy wheels, that is, light alloy wheels.
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.
