Magnesium alloy lightweight structural parts are expected to realize the development from miniaturization to large-scale development: The magnesium alloy auto parts that have been commercialized include steering brackets, steering wheel frames, airbag brackets, pump casings, pump covers, seat brackets, and dashboards. Bracket, door frame, car cover, wheel hub, etc. Due to the difficulty of forging and processing and cost issues, some large structural parts are only used in high-end racing cars. The more common magnesium alloy parts are mainly small structural parts such as steering brackets, instrument panel beams, and steering wheel brackets. In recent years, with the progress of forging technology, the yield rate of large structural parts has gradually increased, and the cost of forging processing has decreased, making prices gradually more competitive, and some large structural parts have become popular.
GM, Mercedes-Benz and other well-known car companies are gradually accepting the application of magnesium alloy wheels: Cadillac, a subsidiary of General Motors, recently announced that forging and spinning (forging + spinning) magnesium alloy wheels will be an optional configuration, which will follow the 2022 CT4-V BLACKWING and CT5 -V BLACKWING models will be launched on the North American market in the summer of 2021. Using this forged magnesium wheel to replace the forged aluminum wheel of the same size can reduce the unsprung mass of more than 8 kilograms, resulting in shorter acceleration time and greater maneuverability, and can enhance fuel economy. In addition to General Motors.
At the end of 2019, the German Mercedes-Benz Design Company and China's leading magnesium alloy wheel manufacturer HNDW Magnesium Technology Group signed a three-year 500 million yuan magnesium alloy wheel purchase agreement. German high-end cars such as Mercedes-Benz, BMW and Porsche are also expected to follow Optional magnesium alloy wheels.
