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.   


Military: deals with the development and manufacturing of products and devices used in various defense applications.  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.
