According to the wheel alloy wheel surface treatment process, different methods will be adopted, which can be roughly divided into two types: baking paint and electroplating.
1. The painted wheels are moderately priced and durable.
The appearance of the wheels of ordinary models is less considered, and good heat dissipation is a basic requirement. The process is basically painted with paint, that is, sprayed and then baked. The cost is economical, the color is beautiful, and the retention time is long, even if the vehicle is scrapped. , The color of the wheel remains unchanged.
The surface treatment process of many Volkswagen car wheels is painted, and some fashionable and dynamic color wheels are also painted. This type of wheel hub is moderately priced and has complete specifications.
2, the price difference of electroplating wheels is large.
Electroplated wheels are divided into silver electroplating, water electroplating and pure electroplating. Although the color of electroplated silver and water electroplated wheels is bright and vivid, but the retention time is short, so the price is relatively cheap, and it is liked by many young people who are looking for freshness.
The pure electroplated wheels have a long color retention time, which can be said to be of high quality and high price. Some mid-to-high-end cars will be equipped with pure electroplated wheels as standard.
Wheel hubs can be divided into two categories according to their materials: steel wheels and alloy wheels.
3. 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, that is, the appearance is not beautiful, the weight is large, the inertial resistance is large, the heat dissipation is relatively poor, and it is very easy to rust.
4. Aluminum alloy wheels have lighter weight, low inertial resistance, high manufacturing precision, small deformation during high-speed rotation, and low inertial resistance, which are beneficial to improve the straight-line driving performance of the car, reduce tire rolling resistance, and reduce fuel consumption.
The thermal conductivity of the alloy material is about three times that of steel, and the heat dissipation is good. It can play a certain role in the thermal attenuation of the vehicle's braking system, tires and braking system.
At present, the alloy wheels of the original cars on the market are mainly 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. Generally, new users will replace the steel wheels immediately after buying a car, the reason is very fuel consumption.
We are engaged in the production and independent import and export of aluminum alloy wheel in china, with more than 2,0000 models of aluminum alloy wheels, about 100,000 inventories, and fast delivery. We provide custom wheels and generation production services, you can provide us with a wheel style map, our designers will design you a beautiful and high quality wheel, welcome to contact us!
