Zinc, 1"shaft x 2 1/8"dia. x 2 1/8"L from CANADA METALS
Canada Metal zincs 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.
