Zinc Alloys

MacDermid Inc. Waterbury, Conn. MacDermid offers a full range of electroplated and mechanical plated zinc alloys providing extended corrosion protection of ferrous metals for the automotive, aerospace, and fastener industries. The SuperZinc and Almac lint of production-proven products can be deposited using conventional equipment and cycles in barrel, rack, or mechanical applications. Alkaline- and acid-based systems exhibit typical performance characteristics of high efficiency, enhanccd distribution, and uniformity of alloy deposit. Zinc-cobalt, zinc-iron, and zinc-nickel electroplated as well as zinc-aluminum and zinc-tin mechanical systems are available. Corrosion protection at 0.3 mil thickness exceeds that of conventional zinc by 34 times. The Macrolloy series of chromates were developed for alloy systems and are available in black, yellow, olive drab, clear, and blue bright colors. Circle 101 on reader information
