Automobile aluminum alloy wheel hub is made of aluminum alloy by forging or casting process. Compared with steel wheels, the advantages mainly lie in the following aspects.

First, the weight is relatively light. Aluminum alloy wheels of the same size are usually two kilograms lighter than steel wheels, and the lighter weight can reduce the resistance when the vehicle starts, accelerates and brakes, thus achieving the effect of fuel saving.

Secondly, the heat dissipation effect is good. It is reported that the thermal conductivity of aluminum alloy material is about three times that of steel material, which means that the heat generated by the vehicle can be transferred to the air more quickly through the aluminum alloy wheel hub during the driving of the vehicle, thus improving the safety performance of the vehicle.

Thirdly, the steel wheel hub looks monotonous, which is seriously inconsistent with people's diversified aesthetic needs. The shape of aluminum alloy wheel hub is more colorful and has more visual impact, which enhances the aesthetic feeling and invisibly enhances the grade sense of the vehicle.

Moreover, the operation is lighter and the driving comfort is better. Due to the lightweight design of the aluminum alloy wheel hub, high precision and strong shock resistance, the general bumps and steering wheel vibrations can be eliminated in time during the driving of the vehicle, making it more flexible and braking when turning, thus improving the handling and driving comfort of the vehicle.

What is the principle of aluminum alloy die forging?

Nowadays, the development of aluminum alloy die forging technology is becoming more and more mature, mainly including aluminum alloy free forging technology, aluminum alloy die forging, aluminum alloy forging heat treatment, aluminum alloy common forging equipment, aluminum alloy die forging new technology and so on. Aluminum alloy die forging means forging will be used in aluminum alloy processing, so what is aluminum alloy die forging?

Light alloy forgings are forgings that use the plasticity and external force of materials to produce plastic deformation to obtain the required shape, size, certain structure and properties. Advantages: The forging structure is compact and uniform, and its performance is better than that of die casting, cutting and welding parts. Mainly divided into warm forging process and cold forging process.

Warm forging is characterized by combining the advantages of cold forging and hot forging, while reducing their respective shortcomings. Compared with cold forging, warm forging blank has small deformation force and easy forming. Large deformation can reduce the number of processes, die cost and punch tonnage, and the service life of the die is longer than that of cold forging. There is no need for pre-softening of the blank and annealing between processes, and it is easier to produce continuously than cold forging.

Cold forging is characterized by material saving, high efficiency and high quality of parts, including high dimensional accuracy and low surface roughness, which can reduce or omit machining and grinding processes, and sometimes heat treatment can be omitted.
