Benchmarking Study of Aluminum Front Suspension Components

A comparative study between two families of front lower control arms manufactured via. Cast-Forge and NRC (New Rheocasting Process) was carried out at Citation Corporation to understand the process capabilities of NRC in automotive suspension applications.

Material property evaluation and component bench test results show significant improvement in strength and durability performance with control arms developed for NRC.

The results also demonstrate unique capabilities of NRC, such as near zero porosity, near net-shape capability, and consistent mechanical properties with high ductility along with tensile & fatigue strength, etc.
