G.RAU produces solid and bimetal rivets from all precious metal alloys and contact materials on double pressure machines as well as by means of cold and warm welding.
Multiple material combinations
Bimetal contact rivets are frequently used to reduce the input weight of precious metal. Hereby the required contact material is mostly cold or warm welded onto the copper base. The contact rivets are manufactured with a pole diameter of 0.7 to 5 mm and a head diameter of 1 to 15 mm. If requested, we can add an electroplated surface layer onto the contact rivet.
Our team would be happy to help you select the suitable materials for your application and submit an appropriate offer to you.
