AGWC-AG COMPOSITE CONTACT, AND MANUFACTURING METHOD THEREOF

摘要

<P>PROBLEM TO BE SOLVED: To provide an AgWC-Ag composite contact combining low surge property and contact resistance characteristics by improving a demerit of contact resistance characteristics of an Ag-WC contact. Ž<P>SOLUTION: The AgWC-Ag composite contact has a contact 6 formed of an AgCu alloy containing 25-75 mass% of Ag, 25-75 mass% of WC and an auxiliary component if necessary; a recess 6a provided substantially at the center part of a contact surface of the contact 6; and Ag films 6b, 6c formed by vapor-depositing an Ag component on angular parts A, B at least on the inner periphery of the recess 6a.
