Aluminum alloy bus bar and method of manufacturing aluminum alloy bus bar

Abstract

An aluminum alloy bus bar includes: a bus bar base material made of an aluminum alloy; and a tin-plated layer formed on at least a part of a surface of the bus bar base material and in direct contact with the surface; in which aluminum in the bus bar base material is directly bonded with tin in the tin-plated layer. The method of manufacturing the aluminum alloy bus bar comprises: preheating the bus bar base material by immersing the bus bar base material in a melt, which is formed by melting metal that constitutes the tin-plated layer, for a predetermined time; applying ultrasonic waves to the melt while the bus bar base material is immersed in the melt; and taking the bus bar base material out of the melt while applying ultrasonic waves to the melt.
