Gamma Z 0.010" 900 N/mm2 P10 22lb/spl is a patented, proprietary wire made under private label for Single Source Technologies by Thermocompact in France. It consists of a high zinc brass core which is coated with a proprietary layer of Gamma Phase brass. The Gamma Phase coating is a discontinuous layer of Cu35Zn65 brass which promotes efficient cutting due to its high zinc content, tenacious bond to the core material, and flushing assist provided by the “porous” nature of the discontinuous coating. Cutting speed increases of up to 50% over plain brass wire and 20% over regular Zinc Coated Brass wire have been reported.
