Silver-coated copper powder, a cost-effective alternative to pure silver, has gained attention for its potential applications in electronics, energy, and catalysis. To explore the impact of heat treatment on its properties, a series of experiments were conducted with temperature increments of 50 ∘C and varying holding times. The silver-coated copper powder was prepared through chemical plating and was heat-treated to assess changes in surface morphology, conductivity, density, and antioxidant performance. Results show that heat treatment significantly improved surface flatness and smoothness, particularly at 600 ∘C for 5 min followed by 700 ∘C for 10 min. After treatment, the specific surface area decreased from 0.2282 m
