VERBESSERUNG DER ELEKTRISCHEN LEITFAEHIGKEIT VON ALUMINIUMLEGIERUNGEN DURCH DIE ZUGABE VON YTTRIUM

摘要

The present invention utilizes the unique addition of yttrium to aluminum base alloys to either enhance the conductivity of such alloys when compared to commercial conductor grade material or provide equivalent conductivity when utilizing grades of aluminum containing higher normal impurity levels. Various processing procedures can be utilized for this material, depending upon the desired final properties.
