First of all, the advantages and disadvantages of the two materials are analyzed.
Steel hub pressure capacity is very strong (large trucks and buses full use of steel ring), toughness (slight deformation will automatically restore), metal fatigue ability is relatively strong, low prices.
The aluminum alloy wheel is lighter, more hardness, wheel hub due to differences in material and processing technology, aluminum alloy wheel type more.
After analyzing the advantages and disadvantages of the material, then look at the ugly appearance of the steel wheel. Maybe we all can't wait to replace the original steel wheel. Don't worry, let's go on talking.
In the actual application process, the actual steel wheel hub is far from our imagination so unbearable. Put a plastic lid on the steel hub and take a look at it. It doesn't look so ugly.
And in the transport process, inevitably when the lateral parking, rub the curb, then usually only scratch the outer plastic shell decoration steel wheels, and the Aluminum Alloy hub, it will be scratched surly, alloy surface is easy to damage. Not careful when hit the curb, because the material toughness Aluminum Alloy is not good, will be more vulnerable, grasps not good time not just rub a steel, aluminum ring easy to be injured, and it is difficult to repair, repair can be deformed to polish, patching putty powder grinding spray paint, do nothing. If the strength is a little bigger, causing deformation, so sorry, you can only change the Aluminum Alloy rim off (with the said steel wheel knock distortion also can change, on the right, if the materials are not solid, steel wheels will also have to change, but the deformation of the steel wheel and Aluminum Alloy hub, is not more than the price of it, too bully people).
Aluminum alloy wheel hub relative to the steel hub, in fact, due to aluminum alloy harder, so the same strength, the energy absorption is better than the steel wheel is good, more prone to fracture. And because of fatigue, aging and other reasons, the life of aluminum alloy wheel hub is shorter than that of steel wheel hub.
Therefore, the new purchase of your car, if not particularly good face of the people, I suggest you do not increase the price of aluminum alloy replacement wheel hub, the money saved, the right as the aluminum ring did not prepare more oil costs. In addition, it is also necessary to remind you that, when not factory parts, car manufacturers do not claim the package!
