The difference between steel wheels and aluminum alloy wheels?

1, the application of different models:

In ordinary life, large trucks, trucks and other relatively large vehicles using the wheels are steel wheels, and now most of the family sedans, SUVs use aluminum alloy wheels, which is because the application of the family car is more beautiful

This is because the aluminum wheels are more beautiful when applied to family cars.

2, the weight is different:

Because aluminum alloy is lighter, so its wheel weight is lighter compared to steel wheels.

3, the hardness is different:

Since the aluminum alloy in the manufacturing process incorporated a large number of advantages of the metal elements, so it has a greater hardness, so the aluminum alloy wheels can withstand a greater pressure. While the steel element itself is harder, but compared to aluminum alloy wheels the degree of hardness is still a little inferior.

4, thermal performance is different:

Because the aluminum alloy wheels have the advantage of fast heat dissipation, so the car in the brakes generated by the heat quickly consumed to extend the service life of the tires and braking system, reduce the wheel blowout chances. The heat dissipation of steel wheels is not as good as aluminum alloy, this is because the steel element is slower to dissipate heat, and often the heat generated by the car is still present in the tire.

5, fuel consumption is different:

Because the weight of aluminum alloy wheels is relatively light, so the car does not consume too much power in the driving process, in driving will reduce fuel consumption. The weight of steel wheels is large, will be part of the power against the driving resistance, which will consume more fuel.
