Problems solved by technology
[0009] However, with respect to such electroplating-treated Al conductive members, in addition to the high cost of the electroplating process itself, there is also a problem that the process of electroplating increases due to the difficulty of plating of Al, which further increases the cost.

Abstract
The aluminum alloy conductive member for a transport device according to the present invention is provided with a substrate formed from an aluminum alloy, and a metal oxide coating film including a metal oxide of an element other than Al formed on the surface of the substrate, the total amount of the metal oxide coating film in terms of metal equivalent mass being 0.1-40 mg / m2, and a component ofthe metal oxide coating film being configured from one or more oxides selected from an element group X comprising Ti, Zr, Hf, V, Nb, Ta, Mo, and W, and one or more oxides selected from an element group Y comprising Zn, In, Mg, Sn, and Ca.
Description
technical field [0001] The invention relates to an aluminum alloy conductive member for transportation equipment. Background technique [0002] The conductive member for electrical connection is a member used when electrically connecting electric wires, connection terminals, electrodes, and the like. Conductive members are used in various products such as office automation equipment, home appliances, and power generation products in addition to automobiles. With the improvement of the performance of these products, the electronic devices and electronic control devices incorporated also tend to increase. Therefore, the amount of conductive members such as bus bars and connectors that are responsible for the electrical connection of such electronic devices and electronic control devices tends to increase. [0003] With regard to conductive members for electrical connection represented by bus bar materials, since electrical conductivity is important, conductive members made o...
