Contact material and manufacturing method of the same.

摘要

It is an object of the present invention to provide contact materials and manufacturing method of the same; said contact materials possess excellent characteristics in terms of contact resistance, corrosion resistance, bending strength, spring property, and ductility. On a band-shaped nickel-claded stainless steel substrate, there is either partially or entirely plated, at least one type of metal selected from noble metals, tin or tin-based alloys. Various evaluating tests including the contact resistance measurements, salt spray tests, sulfur dioxide tests, mixed gas tests of sulfur dioxide and sulfurized gas, and the bending strength tests are carried out on different samples and the results evaluated which showed that the present materials avoid anti-corrosion post-treatment after the press-forming process and exhibit excellent characteristics, particularly suitable to application for intermediate current and intermediate voltage regimes.
