Abstract
The properties of corrosion resistance of aluminium alloy systems, such as, aluminium alloys with copper, copper and silicon, silicon, silicon and magnesium, and magnesium and manganese, to some chemical manures were studied, respectively.
And, as the chemical manures, one percent solution of urea, ammoniwm sulphate, potassium nitrate and potassium phosphate dibasic were used, respectively. Thus, the relationships between the alloy compositions and the chemicals were clarified.
