Mil-Spec Zinc Alloy A-18001H / MIL-A-18001H
MIL-A-18001H
MIL-A-18001H alloy and seawater type zinc anodes available in a wide variety of sizes and shapes
MIL-A-18001H have stable electrochemical properties and are used in seawater or in water resistivity up to 1000 ohm-cm. MIL-18001-H Zinc anodes should not be used where environmental temperature may exceed 50°C.
MIL-A-18001H alloy and seawater type zinc anodes are available in a wide variety of sizes and shapes.
Anodes used in soil usually have a galvanized mild steel rod core. This core is attached to the anode cable during installation of the anode.
In both fresh water and seawater applications the anode is often attached directly to the structure to be protected by welding or bolting the steel rod, pipe, or strap core to the structure.
