Gamma D High Performance Coated EDM Wire is a patented, proprietary wire made under private label for Single Source Technologies by Thermocompact in France.
Gamma D High Performance Coated EDM Wire consists of a Cu80Zn20 brass core which is coated with an intermediate layer of β-phase brass and a proprietary outer layer of γ-phase brass. The patented proprietary gamma-phase coating is a discontinuous layer of Cu35Zn65 brass which promotes efficient cutting due to its high zinc content, a strong bond to the core material, and flushing assist provided by the “porous” nature of the discontinuous coating. The Cu80Zn20 brass core provides the benefits of highly efficient energy transfer similar to copper combined with the increased tensile strength of brass.
Gamma D High Performance Coated EDM Wire provides dramatically increased cutting speeds in nickel alloy and aerospace applications with most machine brands when compared with plain brass wire. Substantial cutting speed increases over traditional “D” type wires have been observed. Gamma D High Performance Coated EDM Wire is available in a wide range of diameters, spool sizes, and spool weights.
