Custom Aerospace Compression Springs - 17-7PH Stainless Steel Material

Custom Aerospace Compression Springs - 17-7PH Stainless Steel Material
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.

Custom Beryllium Copper Wave Washers

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.
