Every car on the road is the result of thousands of engineering decisions, some visible and others buried deep within the chassis. Among these, one of the most fundamental choices is how each component is manufactured. Although often overlooked, the decision to manufacture a component from cast or billet aluminium carries long-term consequences for performance, production speed, and cost.
Aluminium has become vital in automotive design, valued for its ability to reduce weight while maintaining structural integrity. But how it’s processed shapes its final properties. Casting and billet machining offer two very different routes to the same destination: a finished component ready to be bolted into a vehicle.
