American Casting Company produces investment castings in a wide variety of alloys. We have the capability to use both vacuum induction and air induction melting processes.

Air Induction Melting

Used to process mild (low carbon) steels, low alloy steels, stainless steels, cobalt based alloys, and copper based alloys.

Vacuum Induction Melting

Used to process a variety of nickel based super alloys.

This diverse melting capability and alloy selection enables us to serve a variety of markets, including medical, aerospace, defense, electronics, and commercial. The chart below lists the most common investment casting alloys poured at American Casting Company, and their typical mechanical properties for reference. If you are looking for an alloy not shown below, please contact us to find out availability.

NOTE – Mechanical properties listed are for information only. Refer to industry specifications for specific mechanical properties.
