Aluminum alloys are materials that consist of aluminum and at least one other alloying element. They are developed to improve the mechanical, physical and chemical properties of pure aluminum.
Properties
The addition of alloying elements such as copper, magnesium, silicon, zinc or manganese increases strength, corrosion resistance, thermal conductivity and malleability. This allows the alloys to be optimized for specific applications.
Main groups
- Wrought alloys
For products such as sheets, profiles or tubes that are formed by rolling, drawing or forging. Examples: 6061, 7075. - Casting alloys
Specially developed for the casting process, e.g. in the automotive or aviation industry. Examples: AlSi7Mg, AlCu4Ti.
Applications
- Aerospace
Due to its low weight and high strength. - Automotive industry
For body parts, engines or wheel rims. - Construction
In facades, window frames and structural elements. - Electrical engineering
Due to its high electrical conductivity.
Advantages
- Lightweight and robust at the same time.
- Corrosion resistance, often without additional coatings.
- Excellent recyclability, which makes them environmentally friendly.
Aluminum alloys are indispensable materials in modern industries as they offer a unique combination of lightness, versatility and stability.
