Aluminum Alloy
Aluminum alloys are alloys of aluminum with other elements such as copper, magnesium, zinc, silicon, etc. Aluminum alloys have properties such as light weight, high strength, good electrical conductivity and excellent corrosion resistance. Due to these characteristics, aluminum alloys are widely used in a variety of fields such as aerospace, automotive manufacturing, construction, electronics and packaging materials.
Aluminum Alloy Classification
Aluminum alloys are usually classified into two main categories based on composition and production process:
Casting Aluminum Alloys: Aluminum alloys suitable for the casting process are commonly used to manufacture complex shaped parts.
Deformed Aluminum Alloys: Aluminum alloys suitable for forming through mechanical processes (e.g. calendering, extrusion).
Classified according to whether they can be enhanced by heat treatment:
Heat Treatable Aluminum Alloys: These alloys can be enhanced by solution treatment, hardening and aging. Common series include 2xxx (aluminum-copper alloys), 6xxx (aluminum-magnesium-silicon alloys), 7xxx (aluminum-zinc alloys), and others. These alloys are commonly used in applications requiring high strength, such as aerospace and transportation.
Non-Heat Treatable Aluminum Alloys: The strength of these alloys is primarily enhanced by work hardening or by the addition of alloying elements such as manganese and magnesium. They include the 1xxx (pure aluminum), 3xxx (aluminum-manganese alloys), and 5xxx (aluminum-magnesium alloys) series. These materials are commonly used in packaging, construction and marine applications.
