The United States Naval Command joined forces with the International Zinc Institute in the early 1950's to research and improve the performance of common zinc as a sacrificial anode. They discovered the elimination of iron contamination to less than fourteen parts in ten thousand, coupled with the addition of controlled amounts of aluminum and cadmium, enhanced the anodes performance significantly. The research yielded the US Naval Mil-Spec MIL-A-18001 the highest standard of anodes quality.
Why use "Reliance" Anodes?
Reliance anodes are made from a high purity zinc with added catalysts to produce an "activated alloy", ensuring the anodes give one hundred percent of themselves to protect your boat from corrosion action. In order for an anode to work properly it must be free of unwanted impurities.
