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.
