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.
