High Silicon Cast Iron Solid Stick Anode

This solid stick high silicon cast iron anode is made from the iron alloy which contains 14%~18% silicon with excellent acidic and alkali resistance. A porous and semi-conductive film of silicon dioxide (SiO₂) forms on the exterior surface of the anode to prolong anode life expectancy.

Our high silicon cast iron anode is manufactured by our “chill” casting method using gravity to feed the metal mold, which guarantees a rapid solidification of the molten metal. This ensures a superior grain structure is formed in comparison to standard sand-cast anodes, effectively improving anode utilization by up to 60% ~ 70%. Accelerated corrosion tests confirm that our proprietary chill casting anodes yield more ampere-years per pound than the competition.

With an end lead wire connection design, our high silicon cast iron stick anode provides a high performing corrosion protection solution for conventional or deep well cathodic protection systems, shallow installations and grounding cells.
