Metallic material, electroinic component, electronic device and electronic optical component manufactured by using the metallic material and working method of the metallic material

摘要

The metallic material consists of analloy including mainly Cu, Mo in an amount of 0.1 to 3.0% by weight and one or a plurality of elements selected from a group consisting of Al, Au, Ag, Ti, Ni Co and Si in a total amount of 0.1 to 3.0% by weight. In the metallic material, Mo is added to Cu so that Mo will be homogeneously mixed in a grain boundary of Cu, resulting in improvement of atmospheric corrosion resistance.
