Zinc anodes can be problematic when used in
             fresh water. Zinc hydroxide, an insulating layer
             of film, builds up and covers the zinc anodes
             causing failure in their corrosion protection.

             JML’s aluminum anodes are 40% the weight
             of zinc anodes making your vessel’s over all
             weight lighter, allowing better performance.

             Aluminum anodes last up to 50% longer than
             zinc anodes due to the electrochemical capacity
             being 3x’s greater than zinc’s electrochemical

             Aluminum has a high current capacity with a
             low driving potential per pound contributing to
             it’s long life.
             The electrochemical performance makes
             aluminum an ideal galvanic anode material for
             low resistivity environments such as salt and
             brackish waters.

             Aluminum anodes are now the most widely
             used anode for cathodic protection of exposed
             metals to water.
             Aluminum anodes self-clean in fresh water
             as well as activates again upon re-entry to
             the water after hull outs.

             Although magnesium anodes are most popular
             for fresh water usage, aluminum anodes are
             suitable for all types of water making them the
             better choice for boats that travel in salt and
             fresh water.

             Aluminum anodes are designed for optimum
             performance in a variety of temperature ranges
             and environmental conditions.
             JML cast our aluminum anodes in a variey
             of sizes and weights to accomodate all your
             cathodic protection needs.
