Aluminum Aircraft Belleville Washers - Request for Information


Aluminum: is a metal with composition properties that include durability, malleability and a notable weight to strength ration.  Aluminum is one of the most widely used manufacturing materials as a result of its easy machinability and resistance to corrosion. 


Aircraft:  deals with the development and manufacturing of products, structures, materials and devices used in aircrafts.  Aircraft  standards are established based on the extreme temperature, pressure and ware exposure faced in air operations.  


Belleville Washers: are non-flat, cupped washes that provide load-bearing and deflection properties due to a subtitle conical shape.  In addition to introducing spring and flexibility characteristics to the seal, Belleville washers function as locking devices in low dynamic load applications. 

Washers: circular hardware used for spacing, load distribution, sealing and vibration reduction.  Washers are produced through stamping and shaping a variety of materials including various metal, plastic, rubber and fiber.
