O'Fallon Casting is one of the world's foremost manufactures of aluminum, brass, bronze, and aluminum/silicon carbide metal matrix composite investment castings. The investment casting is a versatile and cost effective foundry process that provides accurate, near-net-shape parts that can minimize the need for secondary machining and reduce the part count of your engineered components.
In addition to providing castings from the standard cast alloys of aluminum, brass, and bronze, O'Fallon Casting offers three "specialty" alloys with unique material properties. Our A20X alloy is the strongest commercially available cast aluminum alloy in the world. The aluminum/silicon carbide metal matrix composites provide scalable properties for strength, stiffness, thermal, and electrical conductivity. O'Fallon Casting's IC100 ToughMet® copper-nickel-tin bronze provides strength, stiffness, corrosion resistance, and lubricity that holds up under heavy metal-to-metal loads. For additional information about these specialty alloys please visit the "Alloys" tab of this website.
O'Fallon Casting is located near Saint Louis where it operates a state-of-the-art foundry with many unique capabilities. We hope that you will find the information contained on this website to be useful and that you will return often.
