Custom Beryllium Copper Wave Washers

We supplied our customer 10,000 pcs of these custom beryllium copper wave washers.  They were manufactured domestically in the USA with a relatively long lead time of 14-16 weeks due to the material procurement timing involved.  The ID measures .140 +/- .005" and the OD when flat measures .490 +/-.01".  Thickness of the material is .020 +/-.0004" and the outside height post stamping is .080 +/- .080".  Max load is 26.667 pounds and the max deflection is set at .015.  Parts had to be vacuum aged for 2 hours at 600 degrees to complete the production process.

Custom Steel Spring Washers - Black Oxide Finish

These custom steel spring washers were manufactured using high carbon steel material heat treated to 38-45 HRC with black oxide finish.  When flat, the inside diameter measures .126" and the outside diameter is at .245".  The thickness is set to .004" +/- .005" with our production parts mostly measuring around .007" in thickness.  In it's final shape the OD across the bent sides is at .231" +/- .005".  Production is typically done at 150,000 pieces at a time, which is the MOQ due to the tiny nature of this spring washer.
