Product Introduction
Product Overview
Titanium Conductor Bar is manufactured from Grade 1 titanium ribbon according to ASTM B265 standards. It is designed for current distribution in MMO titanium-based anode cathodic protection systems.
The titanium conductor bar is commonly used together with MMO ribbon anodes and MMO mesh anodes for corrosion protection applications, including above-ground storage tank bottoms, reinforced concrete structures, buried pipelines, and marine environments.
Due to the excellent corrosion resistance and mechanical stability of titanium, it provides reliable current transmission and long service life in aggressive environments.
