Creating parts with investment casting provides extensive alloy choice flexibility. Unlike other processes, investment casting allows foundries to go beyond metals, like iron, steel and brass/bronze. It is excellent for stainless steel, aluminum, duplex alloy and many more. It even accommodates complex and exotic custom alloys designed to achieve specific characteristics and be utilized for highly specialized applications. For best results, it is important to work with a foundry that has an experienced metallurgist and casting professionals.
