Classification of aluminum alloys according to processing technology

Aluminum alloys are widely used in daily life due to their high strength, low density and strong corrosion resistance. However, there are many types of aluminum alloys. They can be classified into cast aluminum alloys, deformed aluminum alloys, forged aluminum alloys, extruded aluminum alloys and rolled aluminum alloys based on processing technology alone.

Classification of aluminum alloys according to processing technology

The following is a detailed explanation of aluminum alloys with various processing technologies:

Cast aluminum alloy: an aluminum alloy material that is directly injected into a mold by cooling and solidifying the molten aluminum alloy liquid after smelting. This type of aluminum alloy has good casting properties and specific mechanical properties, and is suitable for parts with complex shapes that are difficult to manufacture by forging or extrusion. Common cast aluminum alloys include aluminum silicon alloys, aluminum copper alloys, etc.

Deformed aluminum alloy: refers to an aluminum alloy that can be plastically deformed by pressure processing (such as rolling, extrusion, forging, etc.) without destroying its basic properties. Deformed aluminum alloys can be further divided into:

• Non-heat-treated strengthened aluminum alloys (such as 1000 series pure aluminum, 3000 series aluminum-manganese alloys and 5000 series aluminum-magnesium alloys): mainly improve strength through cold working hardening.
• Heat-treated strengthened aluminum alloys (such as 2000 series aluminum-copper alloys,
  6000 Series Aluminum Alloy and 7000 series aluminum-zinc-magnesium-copper alloys): can significantly improve their mechanical properties through heat treatment processes such as solid solution treatment and aging treatment.

Forged aluminum alloy: a type of deformed aluminum alloy, specifically refers to aluminum alloy products processed by forging technology, with higher mechanical properties and finer grain structure, suitable for important parts requiring high strength and high toughness, such as aircraft landing gear, engine parts, etc.

Extruded aluminum alloy: after the aluminum alloy is heated to a plastic state by an extruder, it is forced through a die of a specific shape, and after cooling, aluminum alloy profiles of various cross-sectional shapes are obtained. This process is widely used in construction, transportation, electrical equipment and other fields, such as door and window frames, radiators, rail vehicle structural parts, etc.

Aluminum alloy rolling process

Rolled aluminum alloy: Aluminum alloy slabs are rolled through a rolling mill multiple times to form thinner sheets, strips or foils. These aluminum alloy products have a smooth surface and precise dimensions and are suitable for packaging, building cladding, electronic product housings and other fields.

Each processing technology gives aluminum alloy different physical, chemical and mechanical properties to meet the specific needs of different industries and products.
