1 Explanation of the noun of aluminum alloy wheels
The aluminum alloy wheels have won the favor of more private car owners with their aesthetic, generous, safe and comfort. Now, almost all new models use aluminum alloy wheels, and many car owners and friends also replace the wheels used in the car with aluminum alloy wheels.
Most of the aluminum wheels are based on aluminum as the basic material, and metal elements such as manganese, magnesium, chromium, and titanium are appropriately added. Compared with steel wheels, alloy wheels have the characteristics of energy saving, safety, and comfort, so more and more cars have listed alloy wheels as standard configuration.
2 The three major features of alloy wheels
1. Energy saving
The weight of the alloy wheels is light, the manufacturing accuracy is high, the deformation of the high -speed rotation is small, and the inertia resistance is small, which is conducive to improving the vehicle’s linear driving performance, reducing tire rolling resistance, thereby reducing fuel consumption.
2. Security
The thermal conductivity of aluminum alloy is three times that of steel, which is very good in heat dissipation, thereby enhancing the braking performance, improving the service life of tires and braking discs, and effectively ensuring the safe driving of the car.
3. Comfortable
Cars with alloy hubs are generally used with flat tires with buffer and shock absorption than ordinary tires, so that the comfort is greatly improved when driving on an uneven road or when driving at high speeds.
3 Excellent and disadvantages of aluminum alloy wheel hub
Aluminum alloy wheels are beautiful and generous, lightweight and fuel -saving; aluminum alloy has a high telescopic rate and good elasticity; heat dissipation: aluminum alloy and steel thermal conductivity. The rigidity is good, the skinny is good, and it is not suitable to deform. The wear of each part of the car is small, suitable for high -speed driving; the softness of steel, easy to deform, four -wheel positioning is useless, at high speed (above 160) Life span; good elasticity, improve the smoothness of the vehicle during driving, and easier to absorb vibration and noise in exercise. However, this wheel hub durability is slightly worse.
4 Conservation method of aluminum alloy wheels:
1. When the temperature of the wheel hub is high, it should be cooled naturally before cleaning. Do not wash it with cold water. Otherwise, it will damage the aluminum alloy wheels, and even deform the brake disk to affect the braking effect. In addition, cleaning aluminum alloy wheels at high temperature will make the surface of the wheels a chemical reaction, losing gloss, and affecting beauty.
2. When there are difficult to remove asphalt on the wheel hub, if the general cleaner is not available, you can use a brush to try it out, but do not use a strong brush, especially the iron brush to avoid damage to the surface of the hub. Here, we will introduce a recipe for removing asphalt to the private car owners, that is, the selection of the medicinal “active oil” rubbing, which can achieve unexpected results.
3. If the vehicle is wet or close to the seaside, the wheels should be cleaned frequently to avoid salt corrosion on the aluminum surface.
4. After cleaning, the wheels can be waxed and maintained to make it shiny forever.
