ABSTRACT:
Silver-nickel composite for electrical contacts and electrodes, particularly intended for spark plug electrodes. In order to prevent corrosive attack to the nickel components, the silver component consists of a silver alloy which is impervious to oxygen, and the nickel component is comprised of nickel or of a nickel alloy. This facilitates the manufacture of contacts and electrodes which have a long service life.
