Corrosion-resistant copper materials and making method |
摘要 |
A corrosion-resistant copper material has a surface layer of a copper alloy containing 10-50 at % (i.e. % by atom) of silicon and of 10-1,000 ANGSTROM thick. It is produced simply by annealing a copper material containing 0.01-5 at % of silicon at 100-600 DEG C. in a hydrogen-containing gas. Because of its excellent resistance to surface corrosion due to heat and aging, the resulting copper material lends itself well to automotive and electrical applications requiring heat resistance, and is also suitable for use in electrical wire and in leadframes for semiconductor devices.
