    Zinc Rods

    Image of Product. Front orientation. Zinc. Zinc Rods.
    Cut and thread discs and other parts that draw corrosion away from nearby metal in water tanks, heat exchangers, and marine applications. These rods are made almost purely of zinc and meet MIL-A-18001, which means they break down faster than other types of metal. Attach your parts directly to the materials you want to protect.

    Zinc Foil and Sheets

    Considered commercially pure, this material is 99% zinc.
    Sheets
    Image of Product. Front orientation. Zinc. Zinc Foil and Sheets, Sheets.
    Use sheets to make parts that draw corrosion away from nearby metal in water tanks, heat exchangers, and marine applications. They meet MIL-A-18001 for chemical composition, so they break down faster than other types of metal. Attach them directly to the materials you want to protect.
