MIXED METAL OXIDE ANODES
Mixed metal oxide anodes have very low consumption rates under 1.0 mg/amp-yr, and can be operated at high current densities in fresh water and in salt water. Because of these impressive performance capabilities, Cathoway sdn.bhd manufactures mixed metal oxide probe anodes for use in heater treaters, condenser water boxes and pressure vessels. The anodes are composed of titanium rods, which are covered with a mixed metal oxide coating. The titanium is inherently resilient and stable, allowing the probe anodes to withstand water turbulence without damage. Because the titanium does not discharge current, electrical current transfer is accomplished through the mixed metal oxide coating. The coating is immune to abrupt current reversals and may be exposed to high current overloads for initial structure polarization without causing harm to the anode.

Magnesium Anodes
Magnesium has the highest driving potential of any sacrificial anode. Magnesium anodes are used for corrosion protection in most direct earth burial applications and in higher resistivity, aqueous electrolytes.
Cathoway Sdn.Bhd. provides a complete range of anode types, high potential and standard one and different dimensions for your cathodic protection system.
