The technology is designed for and used in the Bulgarian Metallurgical Plant SOFIA MED SA, Sofia. The copper strips are produced in three different tempers - soft, half hard and hard - under different rolling and heat-treatment conditions. The copper strips from different tempers are subjected to specialized testing and their mechanical and high-electrical-conductivity characteristics analyzed. On the basis of mechanical rolled-strip parameters - yield strengths, R e , ultimate tensile strengths, R m , Vickers hardness, HV, and elongation after fracture, A, - some Stress-hardness and Stress-hardness-elongation spaces have been plotted. These Spaces can be used as an instrument for general evaluation of the applied rolling technology and for prediction of copper-strip mechanical behaviour under given exploitation conditions.enConference Paper
