NON-HEAT TREATMENT TYPE ALUMINUM ALLOY MATERIAL FOR HIGH AMPACITY

摘要

PURPOSE: A non-heat treatment type aluminum alloy material for an over-head power transmission line is provided to obtain improved conductivity and exclude heat treatment by minimizing the amount of additional elements which may cause segregation. CONSTITUTION: A non-heat treatment type aluminum alloy material for an over-head power transmission line comprises Sc 0.05~0.1 weight%. The aluminum alloy material has a tensile strength of 162kgf/mm^2 or greater, a conductivity of 60% IACS or greater, and a heat resistance of 90% or greater.
