Aluminum alloys result when aluminum is combined with one or more other materials such as copper, manganese,
silicon, magnesium, or zinc. Adding these metals makes naturally soft pure aluminum stronger.
The table below shows the chemical composition limits (in percent %) of aluminum alloys, pure aluminum makes up
the remaining percentage
