Materials

DIN and special materials mainly used by us.


The following list exemplarily shows DIN and special materials generally processed by us. we are able to deliver at short notice. In case you need compression springs, extension springs, torsion springs, bent wire parts or rings made from other than the mentioned materials please contact us.

Patented drawn spring steel wire/piano wire (DIN EN 10270-1 DH). For springs exposed to high static or medium dynamic loads. Operating temperature range: -60 to 150°C [1] Not resistant to corrosion.

Stainless spring steel wire (DIN EN 10270-3) Corrosion-resistant to humid air, water and dilute mineral acids such as phosphoric acid, nitric acid and chromic acid. Operating temperature range: -200 to 250°C [1]

Stainless and crack-tested spring steel wire (DIN EN 10270-3 1.4568) For higher loaded springs with higher dynamic loads.

Crack-tested

Corrosion-resistant to humid air, water and dilute mineral acids such as phosphoric acid, nitric acid and chromic acid. Operating temperature range: -200 to 250°C [1]

Hastelloy

Highly corrosion-resistant.
Good resistance to sulfuric acid, phosphoric acid, nitric acid, chlorine.

Seawater proof

Highly resistant to crevice corrosion, pitting and stress corrosion at higher temperatures.

Nimonic

Good mechanical properties at high temperatures. Resistant to oxidation.

Our springs are characterizedby lower production tolerances due to:


Therefore, we are adding the "Factory for Precision-Made Springs" as a subtitle to our company name.

We collaborate with technical universities in different research and development projects.

High precision springs are used inter alia as contact elements, energy storage elements, vibration elements, damping elements or bearing elements in many industries such as:


  • Engineering and Construction
  • Manufacture of tools Hydraulics industry
  • Automotive / Commercial Vehicle Industry
  • Measurement and control technology
  • Filter and fluid technology
  • Electronics and Electrical Engineering
  • Medical technology Environmental Technology
  • Furniture industry
  • Construction industry
