Belleville washers — also termed disc springs or conical spring washers — are precision-stamped or machined annular components manufactured from high-strength spring steels, titanium alloys, or Inconel to aerospace material specifications such as AMS 5112 and NAS standards, providing controlled axial preload, vibration dampening, and thermal expansion compensation within bolted joint assemblies across airframe, engine, and landing-gear applications.
