What are the important alloys of aluminium? What are their uses?

Short Answer

Expert verified
Some important alloys of aluminium are Duralumin, Magnalium, Silumin, Y alloy, and Hiduminium. They are widely used in different sectors, from aircraft and automotive construction to applications where high endurance, lightweight materials are needed.

Step by step solution

01

List the alloys

Research and identify the main alloys of aluminium. Some of them are: Duralumin, Magnalium, Silumin, Y alloy, ZN-alloy, and Hiduminium or R.R. alloys.
02

Describe the alloys

Briefly describe or characterize each alloy. For instance: Duralumin (Al, 3.5-4.5% Cu, 0.5-1% Mg, 0.5-1% Mn) is hard and strong after heat treatment. Hiduminium (a particular Aluminium alloy) contains copper, iron, silicon, magnesium, and manganese, and has high mechanical properties.
03

Describe their uses

Describe where these alloys are generally used. For example, Duralumin is used in aircraft construction, auto parts, and for other lightweight, high-strength applications. Hiduminium alloys, on the other hand, are beneficial where endurance properties and lightness are valuable, and are therefore used in the construction of aircraft engines.
