Top alloy rims provider? At present, the performance test standards of wheel hub mainly include: Japanese JWL VIA standard; German TUV standard; American SAE Standard. German TUV standards are the most stringent, which is why European wheel brands are heavy. The following European BBS 19X8.5J cast wheel hub weighs 11.65KG, compared with other cheap cast wheel 19X8.5J hub weight is 10.68kg. Attached is the hub weight reference table, if you buy a particularly light hub , pay attention. Change HUB SAFETY FIRST!! See more info on alloy wheels supplier.
Gravity casting: Alloy aluminum is melted into liquid state and poured into the casting mold, after cooling and solidification, cleaning treatment to get the casting with predetermined shape, size and performance, after molding for mechanical processing (deburring, trimming appearance, polishing) and made. The casting wheels product needs to be molded according to the requirements, and the price is lower for mass production.
Cast aluminum wheels ultimately need to be processed by CNC machine tools, so no matter the roundness, end direction and radial accuracy of the wheels, they are not comparable to traditional rolled steel rings. The dimensional accuracy of the wheels directly affects the driving performance of the vehicle. Especially for high-speed vehicles, it is more prominent, such as the grip, yaw and stability of the whole vehicle during driving, and braking in case of an accident. The high speed and smooth driving of the car.
If the price of the car is not much different from that of the fuel car, you can choose it, but from the perspective of the current market models, the general car price is more than 20,000 higher than the fuel car of the same level. If you consider the economic cost, it is not recommended to choose a fuel-electric hybrid verb: move. Plug-in hybrid models, the battery life is generally less than 100 kilometers, and the fuel is used when the battery life is exhausted. The price of the car is also much higher than that of the same-level fuel car, but like pure electric vehicles, you can enjoy the green card treatment, only Considering the economic cost, it is also recommended that the higher car price is far more than the extra money for fuel.
The characteristics of high thermal conductivity of aluminum alloy wheels are extremely beneficial to the heat dissipation effect of the car tires due to high-speed driving, so that they are better than steel under the same conditions. It reduces the possibility of hot tires during long-distance high-speed driving, and significantly improves the safety performance of high-speed driving. It is easier to realize the “tubeless” of modern wheels. For a tubeless wheel, the original rubber inner tube is directly replaced by an aluminum rim. If a “puncture object” such as a nail is inserted into the outer wheel while driving, as long as it is not pulled out, it will not be removed. There will be an accident that the car rolls over due to a sudden flat tire like a tire with a tube. After a tubeless wheel encounters a “puncture object”, it can generally last for at least an hour or even longer, which is particularly important for the safety of cars driving on the highway.
