Aluminium is ideal for both complex geometries and rapid prototyping, while providing short machining times and lower tool loads. Whether milling or turning, aluminium ensures an efficient and flexible production process.

A versatile material for CNC machining

Aluminum is one of the most commonly used metals in CNC machining, and it's not without reason. The material combines low weight with high strength and is extremely easy to process. This allows for fast and precise milling and turning with sharp edges, smooth surfaces and fine details. Aluminium is particularly suitable for components where weight optimisation, good thermal conductivity and corrosion resistance play a role – whether for prototypes, technical items or series production. It is used in everything from mechanical parts and enclosures to fittings and special profiles. At CNC Denmark, we work with several popular aluminum alloys such as EN AW-6061, 6082 and 7075, all of which offer high machinability and stable material properties. We ensure precise manufacturing, tight tolerances and the possibility of surface treatment such as anodising. In short, aluminium is a flexible and efficient choice for both development and production – with high quality and low production costs.

Advantages of Aluminum in Precision Machining

When it comes to precision machining, aluminum is one of the most preferred materials on the market. It is lightweight, strong, economical, and highly malleable, making it ideal for CNC processes like milling and turning. Compared to many other metals, aluminum has a lower material resistance, resulting in faster machining times and less wear and tear on tools. A major advantage of aluminum is its ability to maintain structural stability even at thin walls or complex geometries. It is well suited for both single parts and mass production, and it can be easily combined with finishes such as anodizing for both aesthetics and durability. CNC Denmark has extensive experience in machining aluminum alloys for both industrial and technical purposes. Whether you are working with prototypes or want efficient production in larger series, we deliver aluminium components with high precision and proven quality – every time.

Aluminum is a popular material in CNC machining due to its light weight, high strength, and excellent machinability. It is widely used in industry for everything from prototypes to series production, and it allows for the creation of precise and lightweight components with high surface quality.

Sustainable aluminium machining

Aluminum is one of the most recyclable metals in the world. At CNC Denmark, we focus on sustainable production by selecting suppliers who work with recycled materials and energy-efficient processes. The long life and low weight of aluminium also contribute to CO₂ reductions in both production and use. We strive for responsible material consumption and minimize waste through optimized machining and accurate planning.

Quality in aluminium machining

Precision and uniformity are paramount in the manufacture of aluminium parts. We work with high-quality alloys such as EN AW-6061 and 7075 and use modern CNC machines that ensure tight tolerances and flawless finishes. Each part is checked and documentation can be included as needed – whether you need one prototype or a larger series.

Frequently asked
questions

Below we have answered the most common questions we receive from our customers.
You are always welcome to contact us directly for further clarification.

We primarily work with alloys such as EN AW-6061, 6082, 7075 and 5083 – all known for their good strength, machinability and stability. The choice depends on whether your focus is weight, strength, corrosion resistance, or price.
We offer CNC machining with tolerances as low as ±0.01 mm, depending on the geometry and requirements of the workpiece. We use advanced measuring equipment to ensure precision and consistency.
Yes, we offer anodizing, sandblasting, polishing, and other surface treatments depending on aesthetics, abrasion resistance, and corrosion protection requirements.
Yes. Aluminium is suitable for both as it is quick to process, cheap in material and provides a good finish. This makes it ideal for both development phases and large-scale production.
Aluminium is 100% recyclable with no loss of quality. We work with suppliers who use recycled materials and energy-efficient processes to reduce environmental impact.
Aluminum has several advantages compared to metals such as steel and brass. It is lighter, more corrosion-resistant, and easier to machine, which often results in shorter production time and lower costs. At the same time, it provides a nice surface finish and is suitable for both functional and aesthetic components.
