Pure aluminum is soft and fairly weak. It is usually alloyed (mixed) with copper, zinc, magnesium, manganese, and other metals. Aluminum cans are about 98% pure with manganese and magnesium added for strength whereas foils tend to be greater than 99% pure.

ASTM International defines Coiled Foil as aluminum in thicknesses .0005” – .0059”, Coiled Sheets are aluminum in thicknesses .006” – .019”. Other terms of Aluminum Foil include Light Gauge referring to aluminum thicknesses .0001” – .00049” and Heavy Gauge referring to aluminum thicknesses .020” and above. Q.
The shiny side is produced when the aluminium is rolled during the final pass. It is difficult to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers.
Nearly all of the foil presently produced is rolled from non-heat-treatable alloys, which are given H number temper designations for the various specific strain-hardened conditions in which they are made.
opper and aluminum can be combined to form a copper-aluminum alloy. However, under very high temperature, copper and aluminum can form a solid solution. When this solution cools, the intermetallic compound CuAl2, or copper aluminide, can form as a precipitate.
While copper and aluminum can work together, they require special connectors to join these different metals. The problem begins when two dissimilar metals meet; a chemical reaction takes place that causes them to oxidize.
Subsequently, question is, what happens when you mix aluminum and steel? When aluminum and stainless steel are used in an assembly together, the electrons from the aluminum will begin to transfer into the stainless steel. This results in the aluminum weakening. This weakened aluminum causes it to deteriorate at a much faster rate. This can lead to an extended life of the stainless steel.
Beside above, what happens when you mix copper chloride and aluminum?
When you put aluminum in copper chloride, the copper together the chloride eats away at the aluminum. There is noticeable burning smell and some faint smoke as a result of the chemical reaction. As the copper chlorides works away at the aluminum, the aluminum turning into a dark brown color.
