What are the advantages of forging car wheels?

The advantages of forged wheels for automobiles are as follows:

High strength and safety:
- Material structure advantage: During the forging process, the metal blank undergoes plastic deformation under huge pressure, making the internal metal fibers closely arranged along the wheel contour, with finer grains and a uniform structure. This makes the strength and toughness of forged wheels far exceed those of traditional cast wheels. Under conditions such as withstanding heavy pressure, high-speed driving, and encountering complex road conditions or collisions, it is less likely to deform or break, greatly improving driving safety. For example, when suddenly encountering potholes or emergency braking at high speed, forged wheels can better withstand the instantaneous impact force and reduce the risk of wheel damage.
- Higher fatigue resistance: During long-term use, forged wheels can better resist fatigue damage. Compared with cast wheels, they have a longer service life and reduce the safety hazards caused by fatigue damage to wheels.
Lightweight:
- Precise material distribution: The forging process can more precisely control the distribution of materials and remove excess materials, making the wheel as light as possible while ensuring strength. Compared with cast wheels of the same size, forged wheels can generally be about 20% lighter. Reducing the unsprung weight of the vehicle can improve the response speed of the suspension system, making the vehicle more sensitive during acceleration, braking, and steering, and significantly improving handling performance. For example, when cornering, lighter forged wheels can make the vehicle respond faster to the driver's operations and improve cornering speed and stability.
- Reduced fuel consumption: Reducing the overall weight of the vehicle also reduces the resistance that the engine needs to overcome when driving the vehicle, thereby reducing fuel consumption. According to relevant tests, using lightweight forged wheels can save a certain amount of fuel to some extent. For users who use vehicles for a long time, it can save a lot of fuel costs.
Good heat dissipation performance:
- Excellent material characteristics: The aluminum alloy and other materials used for forged wheels themselves have good thermal conductivity. Coupled with the forging process, which makes the material density of the wheel higher, heat can be transferred to the wheel surface and dissipated more quickly.
- Structural design conducive to heat dissipation: The design of forged wheels is usually more scientific and reasonable. For example, the shape and distribution of the spokes can better promote air circulation and improve heat dissipation efficiency. Good heat dissipation performance can effectively reduce the temperature of the braking system, reduce thermal attenuation, ensure the stable performance of the braking system, and prolong the service life of the braking system. At the same time, it also reduces the risk of tire blowouts caused by overheating of the brakes.
High design flexibility:
- Great freedom in shape: The forging process allows designers to create more complex and unique spoke designs, which can meet consumers' demands for personalized appearances. Whether it is a simple and elegant style or a creative shape, forged wheels can be realized, making the vehicle more unique and recognizable. For example, some high-end custom-made forged wheels can be specially designed according to the owner's preferences and the characteristics of the vehicle to perfectly match the overall style of the vehicle.
- Precise size customization: According to the needs of different vehicle models and the special requirements of vehicle owners, the size, pitch circle diameter, offset and other parameters of the wheel can be accurately customized to ensure a higher degree of matching between the wheel and the vehicle and a more fitting installation, further improving the performance and appearance of the vehicle.
Good corrosion resistance: Forged wheels usually use high-quality aluminum alloy materials. These materials have undergone special treatment and processing and have good corrosion resistance. Even in harsh environmental conditions such as humid and salty areas, forged wheels can maintain good appearance and performance, are not easy to rust or corrode, reducing the maintenance cost of wheels and the replacement frequency during the service life.
