MARTYR Streamlined Collar Zinc Anodes with Slot Head Screws

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. Features include a 100% circular radius, interlocking halves, stainless steel hardware and extra alloy around the fasteners.
