Many countries are developing space programs in order to seek undiscovered possibilities and promote human development. A copper alloy called chromium zirconium copper, which maintains the conductivity of copper but has high heat resistance, is used for rocket parts that go to space, a harsh environment. However, producing it is difficult, and there are only a few companies in the world that can stably provide the material. Mitsubishi Materials has succeeded in mass production of high- purity chromium zirconium copper and has been highly evaluated by customers around the world for a long time. Recently, there has been a surge in the number of private companies entering into rocket development, so the frequency of rocket launches is increasing. The demand for rocket parts is also on the rise, and so as to reduce costs, chromium zirconium copper is drawing attention, which has strength for repeated use for engine parts. We will continue to fulfill customer expectations by stably providing high- quality chromium zirconium copper.

Chromium zirconium copper is used in a wide range of fields that require high strength, including automobiles, machinery, molds, iron and steel, heavy electric machinery, home appliances, aircrafts, and ships, in addition to rocket parts. Our company widely provides the copper in the shape of cast cakes and billets.
