Wheel type：
The wheel is also called a rim. According to the characteristics and requirements of different models, the surface treatment process of the hub will adopt different methods, which can be roughly divided into alloy wheel and electroplating wheel.
The alloy wheel has the advantages of light weight, high manufacturing precision, high strength, small inertia resistance, strong heat dissipation capability, good visual effect, etc. The disadvantage is that the manufacturing process is complicated and the cost is high.
Alloy wheels are mostly made of aluminum as a basic material, and metal elements such as manganese, magnesium, chromium and titanium are appropriately added. Compared with steel wheels, alloy wheels are energy-saving, safe and comfortable, so more and more cars have already listed alloy wheel as standard. Let's take a look at the three characteristics of alloy wheel.
1 Energy saving: The alloy wheel has light weight and high manufacturing precision. It has small deformation at high speed and small inertia resistance, which is beneficial to improve the straight running performance of the car and reduce the rolling resistance of the tire, thus reducing fuel consumption.
2 Safety: The thermal conductivity of aluminum alloy is three times that of steel, and the heat dissipation effect is very good, which enhances the braking performance, improves the service life of tires and brake discs, and effectively ensures the safe driving of the car.
3 Comfort: Cars equipped with alloy wheel generally use flat tires with better cushioning and shock absorption performance than ordinary tires, which greatly enhances the comfort of the car on uneven roads or at high speeds.

Electroplating wheels are also divided into electroplating silver, water plating and pure plating. Although the electroplated silver and water electroplating wheels are bright and vivid, they are kept for a short time, so the price is relatively cheap, which is favored by many young people who are pursuing freshness. The market price is between 300 yuan and 500 yuan. Purely plated wheels, long-lasting color, can be said to be high quality and high price. Most high-end cars use purely plated wheels, and the price is about 800-900 yuan.
