Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with annual export value of US$5–10 million, proudly presents our Crest-to-Crest Wave Spring made from premium 17-7PH stainless steel. Designed specifically for aerospace valve assemblies, this spring offers precise force control, exceptional fatigue resistance, and reliable performance in demanding environments. With a free height of 1.0mm, it delivers a compact yet powerful solution for critical sealing and actuation applications.
Our wave springs are engineered to replace traditional coil springs in space-constrained assemblies, providing up to 50% reduction in axial space while maintaining equivalent load capacity. The crest-to-crest design ensures uniform stress distribution, minimizing the risk of failure under cyclic loading. Whether you need a standard configuration or a customized version, our factory leverages decades of wire-forming expertise to meet your exact specifications.
Key Features & Benefits
- Material Excellence: 17-7PH stainless steel offers high strength, corrosion resistance, and excellent spring properties at temperatures up to 300°C (572°F).
- Space-Saving Design: Crest-to-crest configuration reduces installed height by 50% compared to conventional coil springs, ideal for compact valve assemblies.
- Precision Load Control: Consistent force output with minimal tolerance variation, ensuring reliable valve sealing and actuation.
- Fatigue Life: Optimized wave geometry and stress-relieved manufacturing processes extend service life in high-cycle aerospace applications.
- Customizable Parameters: Free height, outer diameter, number of waves, and end conditions can be tailored to your application.
- Surface Finish Options: Passivation, electropolishing, or other coatings available upon request to enhance corrosion resistance.

- Landing gear actuators
- Spacecraft mechanism assemblies
Frequently Asked Questions
-
Q: What is the difference between crest-to-crest and conventional wave springs?
A: Crest-to-crest wave springs have alternating crests that contact each other, creating a more compact axial height for the same load capacity. This design is especially beneficial in tight spaces like valve assemblies where minimizing stack height is critical. -
Q: Can you provide wave springs with a different free height?
A: Yes, we offer fully customizable free height from 0.5 mm to 10 mm. Please specify your requirements, and we will manufacture accordingly. -
Q: Is the 17-7PH material suitable for high-temperature environments?
A: 17-7PH stainless steel maintains its mechanical properties up to 300°C (572°F) and can be heat-treated to achieve higher strength. For temperatures above 300°C, we recommend alternative materials such as Inconel X-750 (available upon request). -
Q: What surface treatments are available?
A: Standard surface is as-rolled. Optional treatments include passivation (to improve corrosion resistance), electropolishing (for smoother finish and reduced friction), and Teflon coating (for low friction). -
Q: How do you ensure the spring’s load consistency?
A: We use computer-controlled coiling machines and automated load testing equipment. Each spring is tested for free height, load at a specified deflection, and dimensional tolerance. Statistical process control (SPC) is implemented in production. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is 500 pieces. For custom designs, MOQ is 1000 pieces. However, we can provide sample quantities (10–50 pieces) for evaluation at a nominal cost. -
Q: Can you provide a certificate of conformance or material test report?
A: Yes, we can provide a material test report from the mill and a certificate of conformance for each order. Please specify your requirements at the time of order. -
Q: How long does it take to receive a sample?
A: Samples are typically produced within 2–3 weeks after order confirmation. For urgent requests, we can expedite to 1 week with additional charges.
