Aluminum wheel advantages
- Jul 07, 2017 -

For the car, the tire is the shoe, the wheel is the foot. The wheels have iron hubs and aluminum wheels of the points, and now the aluminum hub into the standard high-end cars, we say - the benefits of aluminum wheels.


First, fuel-efficient

Aluminum alloy wheels on average each lighter than the steel ring 2 kg, according to the Japanese experiment, steam a car with 5 will save 10 kg weight. According to the Japanese experiment, the car weight per 1 kg reduction, a year can save 12 liters of gasoline, in the same fuel consumption, can run more than 600-800 meters. The kinetic energy generated by the engine, the load to be overcome when the transmission to the tire is the moment of torque, torque = weight x distance of the square, so the weight is only 2 kg, but the difference in torque is quite large. A report published by the American Society of Automotive Engineers pointed out that although the aluminum alloy wheels in foreign countries than the average steel ring is expensive, but each car went to 20,000 km, the fuel savings will be enough to recover the cost.

Second, good heat dissipation

20 degrees Celsius, the metal thermal conductivity: 356.2 aluminum alloy: 0.53, steel: 0.18, chromium: 0.16. It can be seen that the thermal conductivity of aluminum alloy is 3 times the steel, cooling effect is good, long-distance high-speed driving, but also to keep the tire temperature, the brake drum and tire is not easy to aging, increase life expectancy and reduce the chance of puncture.


Three, good roundness good

Precision up to two thousandths of an inch, less than the width of the hair (three thousandths of an inch). Running balance good, to eliminate the general body bumps and steering wheel jitter phenomenon.

Four, durable

Aluminum alloy rim impact resistance, tension and heat and other strength than the ring has gone, and therefore, in the defense industry, the aviation industry has played an extremely important role.

Five, operation light

As the light weight, roundness is good, can control the steering wheel, turn, light and flexible, the brake is also easier.

Six, beautiful

General steel ring due to production constraints, the form of monotonous dull, lack of change, aluminum alloy wheels are all kinds of design, coupled with gloss, color effect, but also improve the car's noble sense of value and aesthetic atmosphere.
