In the field of electrical appliances, a material used for the chassis needs a good electro-conductivity to accomplish a sta- ble ground property in addition to good white rust resistance. On the other hand, in reply to the social requirement of eliminating hexavalent chromium, which is one of the environmentally un-friendly materials, chromate-free treated elec- trogalvanized steel sheet has been developed. "Riverzinc FC-X" has been developed in reply to those requirements. "Riverzinc FC-X" showed good white rust resistance, high electro-conductivity and anti-fingerprinting property.
