Located in Meadville, Pennsylvania, Advanced Cast Products (ACP) is a ductile iron foundry with a programmed Austempered Ductile Iron (ADI) heat-treating line that allows us to boast the only salt-to-salt austempering line in the North American foundry market. ACP’s primary markets include heavy truck, construction equipment, railroad, and mining parts.

For most applications, ACP can complete the entire production process in-house, including casting, machining, austempering, shot peening, protective coating, and assembling. ACP can also provide design and engineering support.

A special area of expertise is Austempered Ductile Iron (ADI). ADI is a range of heat-treated ductile cast irons with high strength, excellent toughness, good fatigue properties, and superior wear characteristics. If strength is a consideration, ADI is one of the most cost-effective materials. Its tensile and yield strengths are at least twice that of standard ductile irons, making ADI a good replacement for structural steels, particularly forgings, and materials that are used in heavy wear applications.
