The mainstream manufacturing processes are classified as follows: 1. Foundry process (*5%): the current mainstream process, relying on cost advantages to occupy the mass market. Sub-categories include: gravity casting: the lowest cost, but prone to porous defects inside the product, and unstable mechanical properties, so it is only suitable for low-end markets; low-pressure casting: a balance between cost and performance, with stable filling, high compactness, and metal utilization rate of over *0%; casting-spinning composite process: a revolutionary new technology developed in recent years, combining casting and spinning technologies, the finished product's strength can reach **0MPa, which is over *0% higher than that of commonly used ****-T6 aluminum alloy, and the damping coefficient is *5 times that of aluminum alloy, achieving an excellent damping effect. However, the material utilization rate is only *0% to *0%, and the production cost is about 2 to 3 times that of foundry. It is currently used in high-performance passenger cars, luxury cars, and aerospace applications. 2. Forging process (*5%): extreme lightweight, directly improving performance: magnesium density is only 1.*4g/cm³, which is 2/3 of that of aluminum alloy and 1/4 of that of steel. A **-inch magnesium alloy wheel weighs only 4.2kg, about 2kg less than an aluminum alloy of the same size. When the whole vehicle is replaced, the weight can be reduced to over *8%, which is equivalent to a body weight reduction of over **0kg. For new energy vehicles, every 1kg of magnesium alloy used can increase the battery life by **8km, and can reduce the problem of excessive tire pressure rise and tail flick when driving at high speed, improving the driving accuracy and safety. 3. Excellent thermal management performance: moderate thermal conductivity of magnesium alloy, which can quickly export brake heat, filtering out road vibrations and reducing powertrain vibrations, making the vehicle more stable and quiet. It can also reduce the front wheel push and rear wheel tail flick during cornering, significantly improving the handling accuracy and safety. 4. More design space: forged magnesium alloy has enough strength to support more slender and concise spoke design, with visual appeal and ergonomics.
