Duralumin is a alloy which mainly consists of aluminium and other metal in small proportion.
Alloying aluminium is to raise the resistiveness and strength of aluminium.
A commonly used modern equivalent of this alloy type is AA2024, which contains (in wt.%) 4.4% copper, 1.5% magnesium and 0.6% manganese.
duralumin is usually
of lower desity and
able to withstand higher temperature
than pure aluminium
usually many alloys are made by cooling after mixing various kind of metals in moten state
due to its high strength and low density, it is widely used in many idustries
Duralumin made of various proportion of metals can be used in different areas
List of typical uses for the wrought Al-Cu alloys:
rivets, hardware, truck wheels, screw machine products, and other miscellaneous structural applications.
bar for screw machine products
diesel engine pistons
aircraft engine cylinder heads
jet engine impellers
Welded space booster oxidizer
supersonic aircraft skin
Die and hand forgings
Pistons and rotating aircraft engine parts for operation at elevated temperatures
