Understanding Of Aluminum Alloy

01 Aluminum alloy

• The general term for alloys based on aluminum. The main alloying elements are copper, silicon, magnesium, zinc, manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc.
• Aluminum alloy has low density but high specific strength, approaching or exceeding high-quality steel, good plasticity, and can be processed into various profiles. It has excellent conductivity, thermal conductivity, and corrosion resistance, and is widely used in industry, with a usage rate second only to steel.
  

02 Classification of Aluminum Alloys

Aluminum alloys are divided into two categories:

1. Casting aluminum alloy for use in the as cast state; Mainly used for manufacturing aviation equipment, daily necessities, building doors and windows, etc.
2. Deformed aluminum alloy, capable of withstanding pressure processing, with mechanical properties higher than as cast state. Can be processed into various forms and specifications of aluminum alloy materials.

03 Aluminum alloy processing methods

Aluminum alloys can be divided into deformed aluminum alloys and cast aluminum alloys according to processing methods.
Deformable aluminum alloys are divided into non heat treatable reinforced aluminum alloys and heat treatable reinforced aluminum alloys.

• The non heat treatment strengthening type cannot improve mechanical properties through heat treatment, and can only be strengthened through cold processing deformation. It mainly includes high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum, and rust proof aluminum.
• Heat treatable reinforced aluminum alloys can improve their mechanical properties through heat treatment methods such as quenching and aging. They can be divided into hard aluminum, forged aluminum, ultra hard aluminum, and special aluminum alloys.

Aluminum alloys can achieve good mechanical, physical, and corrosion resistance properties through heat treatment.
Casting aluminum alloys can be divided into aluminum silicon alloys, aluminum copper alloys, aluminum magnesium alloys, and aluminum zinc alloys according to their chemical composition.
