Abstract： |
The present invention relates to the copper alloy material for lead frame, electrode alloy, microelectronic packing, etc and its production technology. On the basis of traditional CuCrZr alloy, trace elements La and Zn, Fe and Ti are added and the alloy is produced through hot rolling, solid solution treament, cold rolling, ageing and other technological steps. The alloy has balanced comprehensive performance and obviously raised conductivity, tensile strength and hardness compared with traditional CuCrZr alloy. It has relatively simple production process and low material cost. |
