Abstract

Cu-Zn alloy (70/30) alloy is widely used as water tubing in industrial application. From some references reveal that chloride ion exist along pipeline. Interaction between chloride ion and Cu-Zn alloy promote corrosion process then reduce the tube performance. The aim of this research is to improve the corrosion resistance of Cu-Zn alloy by developing TMCP (thermo mechanical controlled process). The specimens are warm rolled at 300°C with reverse rolling system at deformation 25%, 30%, and 35%. Corrosion resistance of specimen is then measured by polarisation method using 0.1 M HCl. Experimental results indicate that by increasing reduction from 31.61% to 48.39%, the corrosion rate decrease from 0.564 mm/year to 0.426 mm/year.
