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.

.042" diameter wire was used to make this custom spring, with OD at .200" and ID at .116". The free length is 1.391". The ends were closed and ground square to spring axis within 1.5 degrees.
