High Silicon Chromium Cast Iron Anodes

For over Four decades High Silicon Cast Iron Anodes have been used successfully in the cathodic protection industry and is one of the most reliable protection materials available. The consumption rate of High Silicon Chrome Cast Iron anodes has been found to be between 0.2 and 1.2 pounds per ampere-year.  A generally accepted design guideline for anodes buried in coke breeze is 0.7 pounds per amp-year. These anodes are available in a number of different styles including solid rod anodes, center connected tubular anodes, and other specialty configurations.

SDP’s High Silicon Chromium Iron anode is a solid, non-porous Impressed Current Anode. This anode alloy consists of matrix of Silico-Ferrite in which the majority of carbon is in the form of graphite flakes at grain boundaries. Adding chromium results in eliminating graphite.

These anodes are available in a number of different styles including solid rod anodes, center connected tubular anodes, and other specialty configurations.
