The patented process gives AMPCO M4 mechanical properties beyond the range of commercial nickel-aluminum bronzes, comparable to beryllium copper at a lower cost and without the beryllium copper industrial hygiene requirements. Applications: AMPCO M4 was initially developed as an aircraft specification alloy for gears in retractable landing assemblies, engine spacer bearings and other similar applications. It is rapidly growing in use where higher mechanical properties at elevated temperatures together with corrosion-resistant properties are required. Typical applications include aircraft landing gear bearings and bushings, bending dies (shoes and mandrels) for the tube bending industry, gear wheels and wear/guide plates, etc.. |
