Metal alloys for forming conductive oxide coatings for electrical contacts

摘要

Described is a metal alloy comprising at least two metal elements which are not precious metals, said alloy being capable of forming a surface metal oxide layer that is conductive having a contact resistivity of 100 Omegacm or less after the alloy has been subjected to 125° C. for 1008 hours. Also described is a process of preparing a metal alloy providing two metal elements which are not precious metals and oxidizing the metal alloy to produce a surface metal oxide layer that is conductive having a contact resistivity of 100 Omega-cm or less after the alloy has been subjected to 125° C. for 1008 hours.
