Steel holds the leading position in rear axle assembly materials because it can handle heavy loads and repeated turning force over long periods. Its established forging and machining processes also support large-scale production, while aluminum is used for selected housings where lower weight is needed without reducing durability.

For electric rear axle systems, manufacturers are expected to choose materials based on available space, heat control and component life. Compact designs bring motors, increasing the need for housings that save space and maintain reliable performance.

Rear axle assembly sales are expected to benefit from continued vehicle production and wider use of electric rear-drive systems. However, changes in factory output, higher trade and manufacturing costs, and frequent vehicle design updates may slow market growth.
