Precious Metal Alloy Strips

Rolled precious metal alloy strips are characterized by their high resistance to corrosion and their excellent mechanical properties.

They are used as source material for contact parts in the medical field, as well as in the automotive and semiconductor industries. Whether as a battery contact, sealing strip, a sliding contact, or as probe needles for testing semiconductor wafers, at Heraeus, the products are manufactured for the customers’ specific needs. For technically sophisticated products such as these, precious metal strips are the material of choice. At the same time, you can manage costs by means of smart production methods such as selective plating.

Our experts will consult with you personally and provide you with further information on the many advantages of our materials.


Precious metal strips have significant advantages compared to other non-precious materials:

  • Highly resistant to corrosion
  • Excellent electrical conductivity
  • Good mechanical properties
  • High degree of reproducibility of the desired material properties
  • Reduction of costs by selective application of precious metals
  • Manufactured according to your individual requirements

In order to guarantee uniformly high quality, we manufacture in accordance with international standards, such as ASTM B540 for Hera 648.


Precious metal strips are used as source material for contact parts in the medical field, as well as in the automotive and semiconductor industries, for example as

  • Battery contacts in hearing aids
  • Probe needles for semiconductor wafer testing
  • Switching contacts
  • Brushes in electric motors and wind power generators
  • Plug-in connectors for safety components in the automotive industry
  • Plug-in connectors for industrial applications, e.g. white goods
  • Sealing elements for lambda probes in the automotive industry
  • Pressure contact for supply technology

Product properties/technical data:

  • Good elastic properties
  • High conductivity
  • Corrosion resistant
  • Cost savings through lower precious metal content
  • Highly ductile
  • Highly wear resistant
