State the uses of aluminium and copper.
(N/A) Aluminium:
$1$. Aluminium foils are used as wrappers for food materials.
$2$. The fine dust of the metal is used in paints and lacquers.
$3$. Aluminium,being highly reactive,is used in the extraction of chromium and manganese from their oxides.
$4$. Aluminium wires are used as electricity conductors.
$5$. Alloys containing aluminium are light and very useful.
Copper:
$1$. Copper is used in making wires for the electrical industry and for water and steam pipes.
$2$. It is also used in several alloys that are tougher than the metal itself,e.g.,brass (with zinc),bronze (with tin),and coinage alloy (with nickel).
