OTHER COPPER ALLOYS
AMS 4880 is a Nickel Aluminium Bronze alloy produced by a continuous cast process, followed by a heat treatment to give the product its full specifications. AMS 4880 is particularly popular for use in landing gear bushings and this alloy benefits from our long experience in continuous casting techniques and grain refining processes that allow us to reach outstanding mechanical properties.
In many cases AMS 4880 produced by AMPCO METAL can substitute for AMS 4640, since it typically it exceeds the mechanical properties of AMS 4640. Additionally, the alloy delivers tremendous costs savings because the hollow bar uses much less material than typical round rods do, due to weight reduction, lower machining costs and elimination of scrap.
