The choice of metal represents a critical component of the sand casting process. Common alloys used in sand casting include cast iron, aluminum, and various steel grades. Each metal has its properties, such as melting point, flow behavior, and strength, which influence the casting process. For instance, gray cast iron is favored for its excellent fluidity and machinability, while aluminum alloys are lauded for their lightweight and corrosion resistance. The selection of metal depends on the application, required mechanical properties, and economic considerations.

1. Tight Tolerances One of the hallmark benefits of precision aluminum casting is the ability to maintain tight tolerances. This is essential for components that require exact fit and function, reducing the need for costly machining processes post-casting.
