The properties of the contact materials are the deciding factors for the reliable function of the contacts.  We develop and manufacture semi-finished products and contact parts from a broad range of contact materials. They are designed for the best performance in their respective areas of applications in the data transfer and communications technology, automotive electrical systems, automation and control technology, as well as low, medium and high voltage energy distribution technologies.

• Contact Materials for Telecommunication and Low Voltage Engineering:
  • Silver and Silver Alloys (Ag and Ag Alloys)
  • Silver-Nickel (Ag/Ni)
  • Silver-Metal Oxides:
    • Ag/SnO₂
    • Ag/ZnO
    • Ag/CdO
  • Silver-Graphite (Ag/C)
  • Silver-Refractory Materials (Ag/W, Ag/WC, Ag/WC/C, Ag/Mo)

• Contact Materials for Medium Voltage Power Engineering
