The Advantages of Magnesium Alloy Forged Wheels

Reduction of Unsprung Mass: Magnesium alloy is currently one of the lightest engineering structural materials. Its density is approximately two-thirds that of aluminum alloy and one-fourth that of steel. Using magnesium alloy forged wheels can significantly reduce the unsprung mass of vehicles, thereby enhancing the handling performance of vehicles. Vehicles will be more agile during acceleration, deceleration and steering, and drivers can obtain more direct road feedback and more precise handling responses. For example, the forged-spun magnesium alloy wheels of Cadillac under General Motors, which are applied to the CT4-V BLACKWING and CT5-V BLACKWING models, can reduce the unsprung mass by more than 8 kilograms, thus resulting in shorter acceleration time and stronger maneuverability.
Reduction of Energy Consumption: The reduction of the unsprung mass of vehicles helps to lower the energy consumption during the driving process of vehicles, improve fuel efficiency, reduce fuel consumption and exhaust emissions, which has certain environmental significance and conforms to the development trend of energy conservation and emission reduction in the current automotive industry.

Advantages of Forging Process: The forging process makes the internal structure of magnesium alloy more compact and the grains refined, thereby increasing the strength and rigidity of the wheels. This enables them to withstand greater loads and stresses without being prone to deformation, cracking and other problems, ensuring the safety and stability of vehicle driving. For example, on some high-performance sports cars and racing cars, magnesium alloy forged wheels can better cope with the powerful impact forces generated during high-speed driving and intense driving.
Tight Molecular Structure: The molecular structure of magnesium alloy forged wheels is tight. Compared with wheels made of other materials, they have higher strength under the same volume, which can save a large amount of materials, reduce production costs, and also help to further reduce the weight of the wheels.

High Thermal Conductivity: Magnesium alloy has a high thermal conductivity, which can quickly and effectively dissipate the heat generated by the braking system, reduce the temperature of the braking system, prevent the performance degradation and safety hazards caused by overheating of the brakes, extend the service life of the braking system, and improve the braking performance and safety of vehicles.

High Damping Coefficient: The damping coefficient of magnesium alloy material is relatively high, which means that it can better absorb and dissipate vibration energy when subjected to dynamic loads, endowing the wheels with superior shock absorption effects. It can reduce the vibration transmission from the engine, transmission and other parts of the vehicle to the vehicle body, making the vehicle drive more smoothly and improving the riding comfort. Especially when passing through bumpy roads or driving at high speed, this shock absorption effect is more obvious.

Good Corrosion Resistance: Magnesium alloy itself has certain resistance to organic matter and alkali corrosion. After appropriate surface treatments, such as micro-arc oxidation, coating and other processes, its corrosion resistance can be further improved, enabling it to be used for a long time under different environmental conditions and extending the service life of the wheels.

Aesthetics: Magnesium alloy material has a good luster and texture. After fine processing and surface treatment, it can present a very beautiful appearance effect, enhancing the overall aesthetics and grade sense of the vehicle, meeting the needs of consumers for personalization and high quality.

Conforming to the Environmental Protection Concept: Magnesium alloy is a recyclable material, conforming to the green environmental protection and sustainable development concept of modern society. The scrapped magnesium alloy forged wheels can be recycled and reprocessed to be reused for producing new magnesium alloy products, reducing resource waste and the impact on the environment.
