Other Zincs Don't Measure Up

We only sell the very best in hand-poured zinc boat anodes from B&S Marine Anodes. All B&S zincs are cast from special alloy zinc that meets Military Specification MIL-A-18001K. Hand poured zinc has a higher degree of porosity due to its molecular make-up than die cast zinc. This is important because in hand poured zinc, size for size, there is a greater area exposed to corrosion than in die cast zinc.
