Magnesium -
0.7
silicon - 0.7
Aluminium remainder
|
Having light weight, one third that of steel. Strong
like mild steel. Can be heat treated and
age-hardened. |
Aircraft sheets, engines and airframe structural
parts rivets, tubes etc. |
|

Alclad |
It is
a duralumin sheet but having coating of pure aluminium on each
side. |
Having all the properties of duralumin with the
resistance to corrosion of aluminium. |
Aircraft sheets and wing
coverings. |

Aluminium
remainder |
Strong as mild steel. Can be heat treated and
age-hardened at low temperatures. |
Used
for making air-craft structural parts, pistons, cylinder heads
etc. |
| 5 |
Aluminium bronze |
Copper - 90
Aluminium - 10 |
It is
a copper-aluminium alloy having high
strength. |
Used
for diecasting and pump-rods also in place of steel for
non-sparking chisels. |
