Aluminium semi-finished products

What are aluminium semi-finished products?

Aluminium semi-finished products are prefabricated aluminium products that are further processed in various industrial and manual sectors. These include aluminium sheets, profiles, bars and plates. They offer an ideal basis for constructions, enclosure manufacturing and technical applications in a wide range of industries.

The versatility and ease of handling of these products make them a preferred choice in modern manufacturing technology.

Properties and advantages of aluminium semi-finished products

Aluminium semi-finished products are characterised by their low weight combined with high strength. They are significantly lighter than many other metals, yet offer impressive stability and load-bearing capacity. Particularly in aerospace and vehicle construction, this property is used to reduce overall weight and increase energy efficiency.

In addition, aluminium is corrosion-resistant, as it forms a natural oxide layer that protects it from external influences. Through additional processes such as anodising or powder coating, the resistance can be increased even further. Another advantage is the excellent machinability.

Aluminium can be easily milled, turned, drilled and anodised, which enables precise shaping and high-quality surfaces. Welded and bonded joints can also be realised efficiently. Added to this is the high recyclability, which makes aluminium a sustainable choice for companies. Almost fully recyclable, it actively contributes to the circular economy and reduces material costs.

Another important characteristic is the high thermal and electrical conductivity. This makes aluminium particularly suitable for heat sinks, electrical components and heat exchangers. This combination of versatile material properties makes aluminium semi-finished products an indispensable material in many areas.

Versatile application possibilities

The fields of application for aluminium semi-finished products are broad. In the automotive industry, they are used to manufacture body parts and engine components in order to make vehicles lighter and therefore more fuel-efficient. In mechanical engineering, aluminium profiles play a central role in the design of precision parts that exhibit both high load-bearing capacity and low friction.

In construction and architecture, aluminium is frequently used due to its weather resistance, whether for façades, window frames or decorative elements. Aluminium is also in demand in electrical engineering, as it offers high electrical conductivity and is therefore ideal for circuit boards and other electrical components. In the aerospace industry, engineers benefit from the lightness and stability of the metal, which is used there for load-bearing structures and interior fittings.

Another significant field of application is medical technology. Aluminium is used in the manufacture of medical devices and instruments, as it is easy to clean and shows no undesirable chemical reactions with bodily fluids. Aluminium also plays a major role in the packaging industry, particularly in the production of aluminium foils and packaging that protect sensitive products from light, moisture and air.

Aluminium alloys – perfect for special requirements

Depending on the application, different aluminium alloys are used. Pure aluminium alloys offer particularly high corrosion resistance and are suitable for environments with high humidity or aggressive chemicals. Aluminium-copper alloys, on the other hand, are characterised by increased strength and hardness and are frequently used in mechanical applications.

For shipbuilding and maritime applications, aluminium-magnesium alloys are used, which offer high seawater resistance. Aluminium-silicon alloys, by contrast, are known for their excellent sliding properties and are therefore particularly suitable for moving mechanical components. This variety of alloys makes it possible to tailor aluminium semi-finished products specifically to particular requirements.

Overview of common aluminium alloys

Alloy type	Properties	Typical application
Pure aluminium	High corrosion resistance	Chemical industry, containers
Aluminium-copper	High strength, medium corrosion	Mechanical engineering, aerospace
Aluminium-magnesium	Seawater-resistant, light	Shipbuilding, offshore installations
Aluminium-silicon	Good sliding properties, durable	Mechanical components

Machining & finishing for highest precision

Our aluminium semi-finished products can be cut to size individually and further processed using the most modern methods. Milling and turning enable precise adaptation to the desired dimensions and requirements.

Anodising and powder coating produce not only durable but also visually appealing surfaces that are advantageous in many applications. Particularly in series production and with complex geometries, CNC machining plays a decisive role, as it guarantees the highest accuracy and repeatability.

For special joining requirements, we also offer welding and bonding techniques that enable stable and load-bearing connections without additional material expenditure. Innovative processes such as laser and waterjet cutting also ensure exact cut pieces with minimal material loss.
