Introduction: The Necessity of Copper Performance Enhancement
In modern industrial systems, copper maintains a pivotal position due to its exceptional electrical conductivity, thermal conductivity, ductility, and corrosion resistance. From power transmission and electronic devices to heat exchangers and architectural decoration, copper applications permeate nearly every sector. However, untreated copper materials are highly susceptible to environmental degradation during prolonged use, leading to performance decay, reduced lifespan, and potential safety hazards.
