An aluminum alloy is a chemical composition where other elements are added to pure aluminum in order to enhance its properties, primarily to increase its strength. These other elements include iron, silicon, copper, magnesium, manganese and zinc at levels that combined may make up as much as 15 percent of the alloy by weight.

Series 7000 . Alloys with zinc. Series 8000 . Alloys with other metallic and non-metallic elements. Toxicity; Contrary to what was considered for decades, aluminum is not safe for human beings. Even so, its degree of toxicity is low, since the aluminum in the diet is absorbed in small amounts by the intestine.

The ZA alloys, like 3, 5 and 7, are based on the zinc-aluminum alloy system, with higher aluminum and copper contents. The other alloying element is magnesium. This common alloy system gives the ZA alloys several characteristics in common with the zinc alloy group: The three alloying elements have essentially the same effect on alloy properties.

A comparative study has been done on three coatings obtained on steel surface using pure Zn, two Zn-Al alloy baths. The coatings obtained using both Zn alloy baths are thinner than the same obtained using pure zinc bath as Al reacts with steel and forms very thin layer of Fe2Al5 phase which hinders iron-zinc reaction. Coating obtained using pure zinc bath predominantly consists of eta (~ 100 ...
