Aluminum alloy wheels: wheel hubs, also known as rims, English name WHEEL. The aluminum alloy hub is made of aluminum alloy wheels. It has the advantages of fast heat dissipation, safety, light weight, energy saving, good comfort and beautiful appearance. The wheels of a car consist of a wheel hub and a tire. It supports the weight of the entire vehicle and allows the car to run on the road, which has a major impact on the performance of the car.

The wheel hub, also known as the wheel, is the part on the wheel where the tire is installed. It is divided into two types: steel wheel hub and aluminum alloy wheel. The former is used for trucks and ordinary cars, and the latter is generally used for high and medium-grade cars. Aluminum alloy wheels are a new species developed in the mid-1980s. They are made by special low-temperature casting techniques. They can combine spokes and wheel rims into a variety of fancy shapes. In the early 1990s, this technology became popular in the field of cars. Nowadays, aluminum alloy wheels have become a symbol of the quality of cars. The car is equipped with an aluminum alloy rim, which has the advantages of rapid heat dissipation, light weight, good comfort and beautiful appearance.

1, heat fast refers to the car at high speeds, the friction between the tire and the ground will produce a higher temperature, brake disc and brake pads friction will also produce a higher temperature, under such high temperature, tires and brake pads Both will age and accelerate wear, brake efficiency will decline, tire pressure will increase, and accidents such as blowouts and brake failures may occur. The heat transfer coefficient of aluminum alloy is 3 times larger than steel, which can quickly transfer the heat generated on tires and brake discs to the air, avoiding the disadvantages caused by the wheels running at high speed.

2, light weight refers to the proportion of aluminum than steel, the average of each aluminum alloy rim is lighter than steel rims about 2 kg, a car with 5 wheels (including a reserve wheel) calculation can reduce the weight of 10 kg . To reduce weight is to save fuel. For car designers who are trying to minimize the weight of cars, using aluminum alloy rims is a means to achieve their goals.

3, Good comfort refers to the aluminum alloy rim is a precision casting, the finishing surface reaches 80% to 90%, out-of-roundness and unbalanced weight is very small, especially the aluminum alloy's smaller elastic modulus, vibration resistance Well, it can reduce the body vibration during driving and improve the comfort of the vehicle.
