Classification Of Hubs
Jan 31, 2018

The market on the hub according to the material can be divided into steel wheels and alloy wheels two categories, both have advantages and disadvantages.

The main advantage of steel wheels is the simple manufacturing process, relatively low cost, and the ability to resist metal fatigue is very strong, that is, we commonly known as cheap and strong. But the shortcomings of the steel wheel is also relatively prominent is the appearance of ugliness (can say no appearance can be said), the weight of larger (the same hub steel material than the aluminum alloy much heavier), inertia resistance, heat dissipation is also relatively poor, and very easy to rust.

Relatively speaking, alloy material wheels just can make up for such a problem, lighter weight, small inertia resistance, high production precision, in the high-speed rotation of small deformation, is conducive to improving the car's straight-line performance, reduce tire rolling resistance, thereby reducing fuel consumption. Alloy material thermal conductivity is about three times times the steel, heat dissipation, for the vehicle braking system, tires and braking systems of thermal attenuation can play a role. The market of the original car alloy wheels are mainly aluminum alloy, of course, many modified wheels to achieve a certain special requirements and visual promotion will choose Chromium, titanium and other elements as the basic materials. However, compared with the steel wheel, alloy wheel price to a lot of expensive, so often in a lot of low-end level of the original car, steel wheels will appear in the low distribution models, and alloy wheels are high matching models standard.
