Six-point advantage of aluminum alloy hubs versus traditional steel hubs

【China Aluminum Network】1

On average, each aluminum alloy wheel is 2kg lighter than a steel wheel hub of the same size. A car can save 5kg with a weight of 10kg. According to the Japanese experiment, the weight of a car for each of the five seats is reduced by 1kg, saving about 20L of gasoline a year. A study published by the American Society of Automotive Engineers pointed out that although aluminum alloy wheels are more expensive than ordinary steel wheels, the cost of fuel saved by each vehicle when it reaches 20,000 km is sufficient to offset costs.

2, increase engine life

According to the engine load and power curve, when the load is increased to a certain extent, the power is reduced inversely. This margin will mean that every 1 unit load at this time, the engine will be more strenuous (especially fuel consumption), and the engine load will be reduced. Naturally reduce failures and extend life.

3, good heat dissipation

The thermal conductivity of aluminum alloy is 3 times that of steel. The heat dissipation effect is good. When the long-distance high-speed driving is performed, the tire can also be maintained at an appropriate temperature, so that the brake drum and the tire can not be easily aged, thereby increasing the life span and reducing the chance of puncture.

4, good roundness

Accuracy up to 0.05mm, good running balance performance, help eliminate the general body length and steering wheel jitter.

5, strong and durable

The impact resistance, tensile strength, and heat resistance of aluminum alloy wheels are higher than those of steel wheels. This is one of the reasons why aluminum alloy plays an important role in the defense industry and aviation industry.

6, beautiful

The general steel hub is limited by production, the form is monotonous and dull, and there is no change; the aluminum alloy hub has a variety of designs, plus gloss and color effect, thereby improving the value and beauty of the car.

Thermostatic Shower Mixer
Thermostatic Shower Mixer also called Thermostatic Mixing Valve, its function is mixed hot water and cold water to pre setting temperature. Thermostatic Shower Mixer Valve can balance the water pressure of hot water and cold water automatically, don`t need to adjust it with hand. Once setting the fixture temperature, cycle using repeatedly, temperature unchanged.
