SUNZO Aerospace-Grade Disc Spring Engineered Elastic Solutions for Critical Mission Systems
SUNZO Aerospace-Grade Disc Spring is engineered to exceed rigorous aerospace requirements, serving as a critical elastic solution for mission-critical systems. These components deliver uncompromising performance under extreme conditions—from cryogenic temperatures to supersonic vibration.
Advanced Material Composition
Material Composition Temperature Range Key Properties
Inconel 718 Ni-52%/Cr-19%/Fe-18% -270°C to 650°C Tensile strength >1,300 MPa
Inconel X-750 Ni-73%/Cr-15%/Ti-2.5% -270°C to 650°C Fatigue life >10⁸ cycles at 70% yield strength
Engineering Advantages
  • Precise load control (0.5-20 kN) with variable stiffness profiles (5-50 N/mm)
  • Proprietary stacking configurations for specific applications
  • 40% reduction in axial space compared to traditional coil springs
  • Critical advantage for weight-sensitive airframe and satellite applications
Stacking Configurations
  • Parallel stacks: High-load applications like landing gear struts
  • Series stacks: Enhanced deflection in engine thrust reversers
  • Nested combinations: Adaptive damping in avionics mounting systems
Quality Assurance & Certification
Each component undergoes aerospace-grade validation including ultrasonic flaw detection (ASTM E164), helium leak testing (<1×10⁻⁹ atm*cc/s), and thermal cycling per MIL-STD-810H. Full compliance with AS9100D quality management standards and Nadcap certification ensures complete traceability from raw material lot to final inspection.
Applications
  • Helicopter rotor dampers
  • Satellite deployment mechanisms
  • Jet engine fuel control valves
  • Reliable energy storage, shock mitigation, and preload maintenance systems
