PROBLEM TO BE SOLVED: To provide a high corrosion resistivity material, improved in corrosion resistivity, adhesion, contact resistance, etc., and low in costs, and manufacturing method therefor. SOLUTION: The high corrosion resistivity material characterized in that a noble metal layer such as Au is provided on the surface of a metallic material such as an iron-based alloy, and they are formed into a clad by rolling with a 5% draft or more. |
