8 Major Application Areas Of Aluminum Alloys

The density of aluminum alloy is 2.7g/cm³, which is roughly 1/3 of steel. Echter, the strength of a specific aluminum alloy is equivalent to that of steel. Daarom, aluminum alloy plays an irreplaceable role in some high-end product applications.

Aluminum alloy materials not only have a high strength-to-weight ratio, but their excellent physical properties also determine the application fields of aluminum alloys.

Characteristics of aluminum alloys

  • 1. Uitstekende elektrische en thermische geleidbaarheid: The electrical and thermal conductivity of aluminum alloy is second only to silver, copper and gold, so it is widely used in fields such as power transmission, radiators and electronic components.
  • 2. Goede corrosiebestendigheid: A dense oxide film (Al2O3) can be formed on the surface of aluminum alloy to prevent further oxidation and provide good corrosion resistance. In aanvulling, its anti-corrosion properties can be further enhanced through methods such as anodization.
  • 3. Easy to process: Aluminum alloy is easy to process through various methods such as casting, extrusie, smeden, and stamping. It is suitable for manufacturing products with complex shapes. It can also be used for secondary processing such as cutting, lassen, and riveting.
  • 4. Good recyclability: Aluminum and its alloys have a high recycling rate. Waste aluminum alloy products can be recycled and reused at low cost and efficiently, meeting environmental protection requirements.
  • 5. Diverse appearance: Aluminum alloy can obtain different appearance effects through a variety of surface treatment methods, such as polishing, zandstralen, anodiseren, elektroforetische coating, enz., to meet the aesthetic and functional needs of different products.

The excellent properties of aluminum alloy determine its wide range of application fields. The following are the 8 major application fields of aluminum alloy.
