SAIC Group Innovation R&D Institute has officially unveiled its second‑generation magnesium alloy housing electric drive assembly and innovative three‑in‑one electric drive assembly, marking a groundbreaking milestone in global new energy vehicle lightweight technology. This flagship product is the world’s first electric drive housing manufactured via advanced semi‑solid process technology with magnesium alloy materials.
As one of the largest magnesium alloy structural components currently applied in the global automotive industry, the new housing achieves an optimal integration of structural innovation, technological breakthroughs, aesthetic design, superior performance, controllable cost and extreme lightweight advantages. Replacing traditional aluminum alloy structures, the magnesium alloy solution reduces component weight by 2.5kg to 7kg per unit.
The upgrade delivers comprehensive vehicle performance improvements. It effectively boosts motor power density, optimizes automotive NVH (noise, vibration and harshness) performance, and balances front‑and‑rear vehicle weight distribution. The overall enhancement significantly upgrades vehicle handling stability and driving experience, solving the core pain points of heavy weight, high energy consumption and limited performance of traditional aluminum alloy electric drive systems.
Magnesium alloy has become a core lightweight material for high‑end motors and new energy vehicles thanks to its low density, high strength, excellent machinability and superior thermal conductivity. In actual industrial applications, magnesium alloy can be widely used in multiple core motor components. Magnesium alloy motor housings greatly reduce overall motor weight and improve operating efficiency, especially suitable for high‑standard scenarios such as electric vehicles and aerospace equipment.
In addition, the material is applicable for high‑precision rotor and stator parts with strict rigidity and quality requirements. Its outstanding thermal conductivity optimizes motor cooling systems, ensuring long‑term stable and efficient operation of high‑performance motors. For medium and small‑sized motors, magnesium alloy brackets, connectors and other structural parts further realize full‑product lightweight iteration.
With the rapid development of new energy vehicles, home appliances and intelligent industrial equipment, motors are evolving toward high efficiency, high reliability and green low‑carbon development. Energy‑saving and intelligent motor technologies have become mainstream industry trends. Meanwhile, advanced manufacturing technologies represented by intelligent die casting and new material forming processes are continuously innovating, helping manufacturers reduce energy consumption, elevate product competitiveness and meet global sustainable development strategies.
As a professional manufacturer of intelligent die casting equipment, Bengbu LongHua Die Casting Machine Co., Ltd. keeps pace with industry lightweight trends. LongHua provides high‑precision, high‑efficiency die casting solutions for magnesium alloy and aluminum alloy auto parts, empowering mass production of new energy vehicle lightweight components with mature intelligent manufacturing technology.
