MARTYR KeelCoolr Zinc Anode is designed for use in saltwater, these zinc anodes are composed of an alloy that meets Mil-Spec MIL-A-18001 for sacrificial anodes. This alloy is mostly zinc, but with measurable concentrations of cadmium (~0.1%) and aluminum (~0.25%). The additional cadmium causes the anode to erode from the surface inward, which causes a “sandblasted” appearance to the surface. When the anode is almost dissolved, it needs to be replaced.
