Patent number: 11094478Abstract: The present invention is a clad material for an electric contact, including a base material composed of a Cu-based, precipitation-type age-hardening material, and a contact material composed of an Ag alloy bonded to the base material. On a bonded interface between the contact material and the base material, a width of a diffusion region including Ag and Cu is 2.0 ?m or shorter. The clad material is produced by bonding each other the contact material and the base material having undergone solutionizing and age-hardening beforehand, suppressing the diffusion region from expanding after bonding. The present invention is capable of providing an electric contact, which achieves higher conductivity, without sacrificing property of the Cu-based, precipitation-type age-hardening material.Type: GrantFiled: May 19, 2017Date of Patent: August 17, 2021Assignee: TANAKA KIKINZOKU KOGYO K.K.Inventors: Takumi Niitsuma, Yoshinori Aoyama, Junichi Takeuchi, Ryuta Ido, Hideya Takahashi
