Introduction to aluminum alloys

Definition and applications of aluminum alloys

Aluminum alloy is a material created by mixing pure aluminum with one or more other metallic elements such as copper, magnesium, silicon, zinc, manganese, or iron. The addition of these elements significantly improves the mechanical properties of pure aluminum, which is soft and difficult to process. Properties such as tensile strength, hardness, corrosion resistance, weldability, and machinability are enhanced, allowing aluminum alloy to be widely used in:

• Manufacturing:Machine components, molds.
• Construction:Structures, facades, doors, frames.
• Transportation:Vehicle bodies, aircraft skins, ships.
• Electronics:Device casings, heat sinks.

Benefits of using aluminum alloys

The use of aluminum alloy offers many outstanding benefits:

• Improved mechanical properties:Increased hardness, strength, wear resistance.
• Lightweight:Helps reduce overall weight, saving fuel in transportation.
• Corrosion resistance:Many alloys have good corrosion resistance in various environments.
• Easy to process:Good formability, cutting, and welding capabilities, suitable for many manufacturing methods.
• Recyclability:Contributes to environmental protection, reduces production costs.

Classification of aluminum alloys

Aluminum alloy are typically classified according to the international four-digit system proposed by the Aluminum Association, where the first digit indicates the main alloying element:

• 1xxx: Pure aluminum (≥99% Al).
• 2xxx: Aluminum-copper alloys.
• 3xxx: Aluminum-manganese alloys.
• 4xxx: Aluminum-silicon alloys.
• 5xxx: Aluminum-magnesium alloys.
• 6xxx: Aluminum-magnesium-silicon alloys.
• 7xxx: Aluminum-zinc alloys.
• 8xxx: Aluminum and other element alloys.
