Gas-saving, durable and beautiful: On the production technology and advantages of aluminum wheel hub

Because alloy hub is lighter with small resistance and its production precision is high, when running fast , the deformation is small, which improves the ability of straight line driving and finally saves fuel. The thermal conductivity of the alloy material is about three times of the steel. Good heat dissipation benefits the thermal decay of vehicle braking system, tire and brake system.

Advantage analysis

The alloy wheels of the original car are mainly aluminum alloy. Compared with steel hub, what advantages does aluminum alloy have?

1. Fuel-saving. Each aluminum alloy wheel hub is 2kg lighter than the same size steel hub on average. A car with 5 wheels will be 10kg lighter. According to a Japanese experiment, for a five-seat car, it will save 20L fuel a year for each kilograms lighter. Regarding to a study published by the American Institute of Automobile Engineers, though aluminum alloy hub is more expensive than common steel hub, but after running 20 thousand km, the fuel cost saved can cover it.

2. Increasing engine life. Engine load is inversely related to the life of the engine. The greater the load, the shorter the engine life. The aluminum alloy wheel hub is lighter than the steel wheel hub, so the service life of the engine can be prolonged.

3. Good heat dissipation. The heat transfer coefficient of aluminum alloy is 3 times of that of steel, and the heat dissipation effect is good. When in the long-distance high-speed driving, it can also keep the tires in the appropriate temperature making it harder for brake drum and tire to age. In one word, it increases tire life and reduces the possibility of blowout.

4. High precision. The circular degree is up to 0.05mm. Operating balance performance is good, which is conducive to the elimination of steering wheel jitter phenomenon.

5. Strong and durable. Resistance to impact, tension and heat and other strength of aluminum alloy wheel hub are stronger than steel wheel hub. It’s also one of the reason why aluminum plays an important role in aerospace and military industries.

6. Beautiful. Limited by production technique, common steel wheel hub is monotonous and lacking in variety. Aluminum alloy wheel hubs have various designs. In addition, the gloss and colors are beautiful. Consequently, it can enhance the value and beauty of your car.
