MMO Ribbon& Ti Conductor Bar
MMO ribbon and mesh are highly conductive anodes with a low consumption rate and life expectancy can be expected to exceed 50 years based on a 3A/M2 current density.
MMO Ribbon consists of a solid ribbon of titanium substrate to ASTM 265 Gr 1 coated with precious mixed metal oxides (IrO2 /Ta2O5). All MMO anodes benefit from being pre-oxidized in a controlled environment prior to field installation meaning they are not reliant on protective film formation when installed and operational. MMO coating is highly conductive and the anodes have a very low consumption rate. This combination of characteristics results in a long-life expectancy even when the anode is subjected to a high current density rating. For example, MMO Ribbon life can exceed 50 yrs. with a 3A/m2 Current Density.
