We supply these custom aerospace compression springs to our aerospace components manufacturing customer. 17-7PH stainless steel material is used for the domestic production of these parts, per AMS 5673-F. Our production runs are typically in the smaller 500 piece quantity range for this specific spring, with lead time at 8-10 weeks. That lead time includes passivation per AMS QQ-P-35, and penetrant inspection per ASTM E 1417 Type I, Method A, Sensitivity L-3. Each one of those two processes typically takes about 1 week to complete.
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.
