Beryllium Copper Aerospace Belleville Washers - Request for Information


Beryllium Copper: is a metal alloy composed of copper and beryllium.  It is primarily utilized for its properties of weldablity, resistance to non-oxidizing acids, and for its flexibility and shape retention.   


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