Traditional metal housing are typically made of cast iron or aluminum alloy. While cast iron is too heavy, aluminum alloy-though lighter than cast iron-still has room for further weight reduction. The emergence of magnesium alloy housings has brought a qualitative breakthrough. As a lightweight metal, magnesium has a density only two-thirds that of aluminum and one-quarter that of steel, making it even lighter than common engineering plastics. Yet, it retains the strength and rigidity of metal.
In the field of new energy vehicles, key components such as the electric drive system (including the motor, electronic controller, and reducer) serve as the "heart" of an electric vehicle. However, batteries and electric drive systems account for a significant portion of the vehicle's total weight. Studies show that a 10% reduction in the weight of a new energy vehicle can increase its driving range by 6% to 8%. As a result, magnesium alloy products are increasingly favored by new energy vehicle manufacturers. Applications such as motor enclosures, electric drive housings, controller casings, wheels, subframes, and battery pack covers are continuously expanding for magnesium alloys.
EXCELLENCE IN INNOVATION
Simons Company has made continuous progress in high-performance magnesium alloy materials and forming technologies for thin-walled complex components. By optimizing alloy formulations and casting processes, along with incorporating flame retardants to enhance production safety, the company has gradually overcome key challenges related to the strength, toughness, and stability of lightweight structural parts.
