COPPER-BASED ALLOYS WITH OPTIMIZED HARDNESS AND HIGH CONDUCTIVITY
Keywords:
conductivity improvement; hardened copper alloy; high performance copper alloy; conduction materials; electrical and automotive engineering.Abstract
Copper alloys, combining optimized strength with high electrical and thermal conductivity, are analyzed in-depth, in order to meet the increasing requirements of today’s and tomorrow’s applications in the electrical and automotive industries. The conducted research analyzes alloys with up
to 0.3 wt.% scandium, as an alloying element with limited solubility in copper. For the simultaneous enhancement of mechanical strength and conductivity, precipitation hardening is the conducted process method, accompanied by experimental and simulation-based investigations. Therefore, the influence of aging temperatures, in the range of 350 ◦C to 500 ◦C, is analyzed in combination with 25%, 50%, and 75% prior cold deformation
