The results of investigations the corrosion resistance Al-Mg-Sc-Zr alloys with varying Mg content and different Sc/Zr ratios are presented. objects were total Sc + Zr 0.32 wt%. concentration in varied increments 0.02 produced by induction casting. effect annealing temperature on microhardness electrical resistivity was investigated. Corrosion tests carried out a medium simulating intergranular aluminum alloys. Electrochemical studies mass loss performed. An increase decrease one shown to result an rate. primary Al3(ScxZr1-x) particles found have main dependence current alloy non-monotonous character (with maximum).
