Abstract
Over the recent years, heat resistant aluminium alloys have enjoyed a lot of interest in the power engineering industry. Among these, the most popular are alloys with the addition of zirconium. These materials are used mainly in the production of overground wires with the increased current load-carrying capacity of the HTLS type (High Temperature Low Sag). These alloys are characterised by complex properties. In the article we present the results of tests of a new AlZr alloy production technology which is based on the process of continuous casting of the semi-finished products later used in the drawing process. The aim of this paper is to determine the effect of heat treatment conditions on the value of the resistivity of aluminum with the addition of 0.22% mass. Zr, and on that basis determine the optimum range of annealing process parameters of the alloy.
