Aluminum Aerospace Flat 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. 


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.  


Flat Washers:  primarily used with other hardware, such as nuts and bolts to distribute forces in the process of tightening.  Tightness is determined by pattern features such as nominal screw sizes, screw pitch thread, interior and exterior diameter ratios and height. 


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.
