Product Details
Product Introduction
Our Contact Rivets are precision-engineered bimetallic and trimetallic components combining silver alloy contact faces (AgNi, AgSnO₂, AgSnO₂In₂O₃, AgCu, Ag, AgZnO, AgCuO) with copper or brass rivet bodies (Cu, brass). Designed for high-speed automated assembly, each rivet features consistent head geometry, accurate dimensions, and reliable bonding between contact material and base metal. Monthly capacity of 50 million pieces supports mass production of relays, contactors, MCBs, miniature switches, and temperature controllers for global electrical equipment manufacturers.
