Influence of Heat Treatment on the Structure and Properties of an Al–7% REM Conductive Aluminum Alloy Casted in an Electromagnetic Crystallizer

A comparative analysis of a wire of the Al–7% REM thermostable conductive alloy produced by casting into an electromagnetic crystallizer (EMC) and using the granular technology (RS/PM) method has been carried out. The effect of the annealing temperature (up to 600°C) on the structure of Al–7% REM rods produced using the EMC technology has been studied. Mechanical properties and specific electrical resistivity of the thermostable aluminum wire have been analyzed. It has been shown that the physicomechanical properties of the wire made of the rod cast into an EMC are comparable to those of RS/PM-produced wire.
