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.
Large quantities of these custom made copper wave washers are best supplied on a 12 month blanket purchase order basis. The Blanket Order concept allows the customer to access the large quantity cost savings without paying upfront for the entire large quantity order. Instead we take on the burden of carrying the bulk inventory and only release the parts as needed, or often on a pre-scheduled basis provided by the customer.
