Dependence of Corrosion Resistance for Aluminum Alloys with Composition Increased Impurity Content

The effect of the main impurities, added separately to an alloy, on aluminum-magnesium alloy corrosion resistance, and also in combination on the corrosion properties of secondary cast alloy AMg5K is studied. Comparative tests are conducted for corrosion resistance of industrial silumin and magnalium under different climatic conditions. Experimental results are provided for a study of the effect of alloy composition on corrosion properties under different climatic conditions.
