CATHODIC PROTECTION: MAGNESIUM ANODES

HIGH-POTENTIAL CAST MAGNESIUM ANODES

CMP offers the most powerful protection available today with our line of Hi-Potential Cast Magnesium anodes. Cast from high-purity magnesium to ASTM B-843 specifications; these anodes produce an open circuit potential of 1.77-1.82 volts. Efficiency of the anode can be further enhanced when installed in a backfill of 75% gypsum, 20% bentonite and 5% sodium sulfate. This mixture allows optimal electrical current to flow more easily to the targeted structure by lowering the anode to earth resistance.

All CMP anodes are manufactured to strict quality control standards and ongoing audits to ensure the highest quality that our customers have come to appreciate and expect.

CMP Hi-Potential Cast Magnesium anodes are available packaged in a water permeable cardboard tube or cotton bag in a low resistivity, quick wetting prepared backfill material. All anodes are available with a wide variety of connecting wires.

Aluminum: 0.01%, Manganese: 0.50-1.3%, Silicon: 0.05%,
Copper: 0.02%, Nickel: 0.001, Iron: 0.003,
Others, Total: 0.30%, Magnesium: Remainder.

ZINC ANODES AND TRACER WIRE

HIGH-POTENTIAL CAST ZINC ANODES

CMP’s full line up of Zinc packaged anodes are the most widely used and effective choice for preventing corrosion on selected soils. All zinc anodes are made to ASTM B-418, Type II alloy standard, allowing these anodes to produce and open circuit of 1.1 volts.

All packaged anodes are prepackaged in low resistivity, quick wetting prepared backfill consisting of 75% gypsum, 20% bentonite and 5% sodium sulfate. This mixture allows optimal electrical current to flow more easily to the targeted structure by lowering the anode to earth resistance. Zinc packaged anodes offer a 90% current efficiency and delivery a current capacity of 335 amp. hrs/lb. All our anodes are manufactured to strict quality control standards and ongoing audits to ensure the highest quality that our customers have come to appreciate and expect.

All packaged anodes are prepackaged in cardboard tubes with low resistivity.

Chemical Composition - ASTM B 418 Type II: Aluminum: 0.005% max,
Cadmium: 0.003% max, Iron:0.0014 max, Lead: 0.003 max,
Copper:0.002 max, Zinc: Remainder.
