NOVELTY - High-conductivity silver-copper alloy comprises silver-copper alloy main body and reinforced medium doped in alloy main body. The silver-copper alloy main body comprises 0.025-0.040 wt.% silver, less than 0.05 wt.% unavoidable impurity element, and rest is copper. The reinforced medium is rare earth modified graphene doped with aluminum bronze. USE - High conductive silver-copper alloy for copper sheet of commutator. ADVANTAGE - The high-conductivity silver-copper alloy has reduced harmful gas content, more compact and stable crystal structure, excellent conductivity, improved wear resistance, and improved comprehensive benefit.
