Special Springs for Aerospace

This family of springs include spring or 'Belleville' washers as well as any part made of strip metal which has a spring effect.

Thanks to our engineering workshops, we can cut and shape these components according to specification, from our large range of stock materials, and supply them in small or large production runs.

Ressorts Masselin's production capabilities allows spring production using a variety of materials :

  • Wire or strip steel from 0.2 mm
  • Spring steel according to EN 10 270 standard for class SH-DH and EN 10 270-2 for oil tempered wires
  • Stainless steel to standard EN 10 270-3
  • Special alloys like Ube2, titanium, nimonic, inconel according to AMS / ASTM spec. or to customer specification
