Mitsubishi materials' high performance oxygen free copper and high performance alloys

Mitsubishi Materials has many years of experience in the production of oxygen free copper (OFC) and its alloys with a fully continuous casting process. Four grades of OFC, commercial, electronic, superconductor, and ASTM class 1 are available according to user needs such as stabilizer for superconductivity, magnetron, and ultra vacuum systems. Along with Cu-Ag and Cu-Sn, we offer OFC based copper alloys such as Cu-Cr-Zr, Cu-Fe-P, Cu-Ni-Si and others, that are suitable for lead frame and connectors. Within the maximum sizes of 260mm X 1050mm for cakes and 385mm diameter for billets, we are very flexible and can adjust the ingot size to customer's requirements. Other products that we can supply are semi finished products such as hot rolled sheet, forged blank, extruded rod and finished products like mold for continuous casting of steel, ring mold for non-ferrous casting and backing plate for sputtering target.
