THE SINTERED COPPER POWDER

Abstract

Open-ended Terms: SAP, SCP.A study was made of the structure, resistivity, oxidation resistance, mechanical properties, and manufacturing processes of sintered Cu powder when alumina, silica, or magnesia is added. With addition of Al2O3 powder to sintered Cu powder the strength is 50% and the hardness 100 to 200% higher than those of Cu at temperatures of 20 to 800 C; the recrystallization temperature is shifted from 300 C to 600 to 700 C. The electrical conductivity with 1 to 3% Al2O3 by volume is 87 to 93% that of Cu, while oxidation resistance is higher. The strength and hardness of the sintered product increase when very finely powdered Al2O3 is used. (Author)
