◎Zinc Alloys Sacrificial Anodes - Our zinc anodes are suitable for cathodic protection of steel structures in ships, harbor facilities, marine engineering, buried metal pipelines, storage tanks, seawater cooling water systems, etc. The zinc alloy sacrificial anodes are produced according to the national standard GB/T4950-2002 "Zinc-Aluminum-Cadmium Alloy Sacrificial Anodes" and meet the SY/T0019-97 "Design Code for Cathodic Protection of Buried Steel Pipe Sacrificial Anodes." The chemical composition of the zinc anode conforms to USMIL-A-18001H and ASTM-B418 (Type 1) standards. Chemical composition of zinc alloy sacrificial anode: AlCd impurities, not more than FeCuPbSiZn content % 0.3-0.6 0.05-0.12 0.005 0.005 0.006 0.125 Balance zinc. Electrochemical properties of zinc alloy sacrificial anode: Open Circuit Potential -V(SCE) Working Potential -V(SCE) Actual Capacity A·h/kg Current Efficiency % Dissolution Condition in Seawater -1.09~-1.05 -1.05~-1.00 ≥780 ≥95 Corrosion products are easy to fall off, surface dissolution is uniform.
