Aluminum Milspec 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. 


Milspec: Military standards are most often defined by an efficient operation and substantial longevity in inhospitable or rugged conditions and environments.  


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.
