Electric contact material for automobile mounted relay and vehicle mounted relay using it

摘要

The purpose of this study is to provide an electrical contact material for automobile mounted relays with excellent durability when used for inductive load of magnet clutches of automotive air conditioners, and to provide high durability durability for automotive mounting Provide relays. The present invention relates to an Ag-SnO 2-in2o3 alloy obtained by internally oxidizing an Ag Sn in alloy comprising 5.0 to 10 wt% Sn, 2.0 to 5.0 wt% in, and Ag in the remainder AG, or 5.0 to 10 wt% of Sn, from 2.0 to 5.0% by weight, and 0.01 to An Ag Sn in Ni 3-nio alloy obtained by internal oxidation of Ag Sn in Ni alloy is used as an electrical contact material for automotive relay.
