Automobiles support our life as a means of movement and transportation, and our wrought copper products are an essential part of them. They are produced by processing copper or copper alloy.
Because of their excellent electrical and thermal conductivity, they are used in various parts, such as wire harness terminals, the “blood vessels and nerves” of an automobile, and the components of the junction box, which houses cables for electric systems and control circuits.
Our company started focusing on products for automobiles about 30 years ago. As domestic vehicle manufacturers started developing next-generation automobiles one after another, Mitsubishi Shindoh (currently Mitsubishi Materials) focused on copper alloy, which was well adapted to the characteristics of next- generation automobiles. We have been providing a wide range of products by making use of our historic metallic materials technologies and now have the No.1 market share in wrought copper products for automobiles in Japan.
With the popularization of electric vehicles, the demand for copper alloy continues to increase progressively because the means of energy transmission is shifting from engines to motors, and from gasoline to electricity. Even though the required functions for automobiles have been changing, we will pursue the high quality only we can realize and continue to stably provide wrought copper products to domestic and overseas customers.

We have three types of MSP that have a different amount of magnesium added to the copper, according to the customer’s application. The series aids the electrification of various products, including automobiles.
