Nickel Aluminum Bronze (AMS 4881) Applications

The main application for nickel aluminum bronze in the aerospace sector is landing gear bearings for the world’s fleet of commercial aircraft. The excellent bearing properties against steel, corrosion resistance in salt conditions during de-icing of runways in winter and high mechanical properties make it an ideal alloy for this application. The main specifications are AMS 4640, AMS 4880, AMS 4881 and AMS 4590, BS2 B 23, NFL14-702, NFL14-705 and NFL14-706. The aircraft companies and main subcontractors also have their own specifications, for example, Airbus ASN-A 3406, ASN-A 3315, ASN-A6127A and Rolls Royce MSRR 8503.
