Properties and Uses of Aluminium.
Properties.
Aluminium
1) is strong, malleable and has a
low density.
2) is resistant to corrosion.
3) is a good
conductor of heat and electricity.
4) can be polished to give a
highly reflective surface.
Uses.
1) Low density and strength make it ideal for
construction of aircraft, lightweight
vehicles, and ladders.
An alloy of aluminium called duralumin
is often used
instead of pure aluminium because of its improved properties.
2) Easy
shaping and corrosion
resistance make it a good
material
for drink cans
and roofing materials.
3) Corrosion
resistance and low density
leads to its use
for
greenhouses and window frames.
4) Good conduction of
heat leads to its use
for boilers, cookers and
cookware.
5) Good conduction of
electricity leads to its use
for overhead power cables hung from pylons
(low density gives it an advantage over copper).
6) High reflectivity
makes it ideal for
mirrors,
reflectors and
heat resistant
clothing for fire fighting.
