Abstract
A micro-alloyed copper powder was produced using gas atomization reaction synthesis, with the alloy preferably comprising Cu-0.3Zr-0.15Ag wt. %. The novel copper alloy improves the manufacturability of copper in powder bed fusion manufacturing processes by minimizing or avoiding the prior art problems associated with oxidation of the copper precursor used in additive manufacturing. Advantageously, the provided copper alloy powder maintains the high electrical conductivity of copper while addressing the prior art oxidation issue.
