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

more corrosion-resistive,

stronger,

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:

Wire

truck frame

Aircraft structures

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

compressor rings

Welded space booster oxidizer

fuel tanks

supersonic aircraft skin

structure components.

Die and hand forgings

Pistons and rotating aircraft engine parts for operation at elevated temperatures

Tire molds
