Optima® titanium wire anodes are ideally suited for cathodic protection applications. The mixed metal oxide catalytic coating is sintered to the titanium substrate, providing a lightweight, durable anode.

With the proprietary catalyst used, Optima IOA-HF electrodes, are suitable for use in the widest range of cathodic protection applications including soil, carbonaceous backfill, fresh water, brackish water, and seawater.

The consumption rate of the mixed metal oxide coating is measured in milligrams per ampere-year. This low mass consumption rate combined with the unmatched strength-to-weight ratio for the titanium substrate results in unique advantages for the Optima anodes.
