The Advantages of Aluminium CNC Services for Manufacturers

The combination of the use of Aluminium as a machining material and the use of CNC Machining offers numerous advantages over traditional manufacturing techniques.

Each contributes its specific advantages to the machining process, providing numerous benefits:

Advantages of using CNC Machining

CNC Machining is essentially using a computer-controlled robot to perform machining tasks. The machine performs a series of machining tasks to accurately remove metal from a block of aluminium to sculpt it into the desired component. Sophisticated 3D design software sends the necessary information to the CNC machine to control it to remove the excess metal – literally carving the desired shape out of a block of aluminum.

High Precision and Consistency

CNC machines, being computer-controlled, can produce parts with high precision and consistency. This means that every part machined will have the same dimensions, tolerances, and quality as specified.

Speed of Production

CNC machining can produce parts quickly, especially when working with aluminium, which is softer than many other metals. This allows for faster feed rates and quicker turn-around times for batches.

Reduced waste

Precision means less waste. Ensuring that every cut and drill is accurate reduces the chance of producing defective parts that would otherwise go to waste.

Flexibility in Design

The digital nature of CNC machining allows for easy adjustments to the design. This is especially useful for prototyping, where designs may need several iterations before they are finalised.

Suitable for Large and Small Batch Production

CNC machines can be cost-effective for both large and small production runs. The speed and efficiency of production often offsets setup costs. CNC is ideally suited to prototyping where several design and fabrication iterations may be required to finalise the product design, then can be immediately manufactured at scale.

Complex Geometries

CNC machining can produce parts with complex geometries that might be difficult or impossible to achieve with traditional machining methods.

Safe and Clean

CNC machines are generally safer for operators since the entire machining process is enclosed. This reduces the risk of accidents. Additionally, aluminium shavings and chips are easier to manage and recycle.

Integration with Modern Software

Modern CNC machines can integrate seamlessly with CAD/CAM software, allowing manufacturers to streamline the design-to-production process.

Reduced Lead Times

With the integration of modern software and the rapid machining capabilities when working with aluminium, manufacturers can reduce their lead times significantly. This ensures that products reach the market faster, giving manufacturers a competitive edge.

Advantages of manufacturing using Aluminium.

Aluminium has a number of characteristics that make it more suitable for manufacturing, and especially CNC machining:

Strength to weight

Aluminum offers an excellent strength-to-weight ratio, making it an ideal choice for parts that need to be both strong and lightweight. This is particularly beneficial for the aerospace and automotive industries.

Corrosion Resistance

Many grades of aluminium have natural corrosion resistance, which can be further enhanced with anodizing or other finishes. This makes aluminium parts durable in various environments.

Reduced Tool Wear

Aluminum, being softer than many metals, tends to be less abrasive on cutting tools. This can lead to longer tool life and reduced tool replacement costs.

Energy Efficiency

Aluminium conducts heat efficiently. This property helps dissipate heat quickly during the machining process, reducing the need for excessive coolant and making the process more energy-efficient.

Easy Finishing

Aluminium can be easily anodised, painted, or finished in various ways to improve its appearance or enhance its surface properties.


Aluminum is highly recyclable, and its recycling process requires significantly less energy than producing new aluminium. By choosing aluminium, manufacturers are also supporting sustainable and environmentally friendly practices.

Expanding Applications

As technology advances, new applications for aluminium CNC parts are emerging. From robotics to renewable energy infrastructure, the potential uses for precision-machined aluminium parts are expanding, making it a future-proof choice for manufacturers.

Noise and Vibration Dampening

Aluminium has inherent properties that help in dampening noise and vibrations. This makes it especially suitable for applications where noise reduction is crucial, such as in automotive components or in certain industrial machinery.

In addition to the advantages described above, the combination of Aluminium and CNC Machining also provides:

Consistent Quality for Critical Components

There’s no room for error in industries like aerospace or medical device manufacturing. Aluminium CNC services’ high precision and consistency ensure that even the most critical components meet stringent industry standards every time.

Adaptability to Industry Trends

One of the key strengths of aluminium CNC machining is its adaptability. As industries evolve and embrace new technologies or methods, aluminium CNC machining can accommodate these shifts with ease. Whether aerospace, automotive, or consumer electronics, CNC services with aluminium can meet varying requirements head-on.

Understanding Aluminium Grades

Firstly, it’s important to select the appropriate grade of aluminium. Common machining grades include:

  • 6061: General-purpose grade with great strength and good corrosion resistance.
  • 7075: Aerospace grade with high strength but less corrosion resistance than 6061.
  • 2024: High strength with good fatigue resistance but more prone to corrosion.
  • 5052: Lower strength but high corrosion resistance and excellent weldability.

Each grade has unique properties that affect machinability, such as hardness, which can affect tool wear, and chemical composition, which can impact surface finish

Aluminium 6061

Aluminum 6061 is a widely used alloy in the aluminum series, known for its versatility and balanced properties.

It’s composed mainly of aluminum, magnesium, and silicon, along with traces of other elements like copper, zinc, manganese, chromium, and iron.

Aluminum 6061 is widely used in many industrial applications. It’s found in aerospace components, automotive parts, bicycle frames, construction materials (like window frames and doors), and in the manufacture of water, air, and hydraulic piping systems.

Aluminium 7075

Aluminum 7075 is a high-strength alloy that’s widely used in the aerospace and defense industries, among others.

It’s known for its excellent mechanical properties, making it a preferred choice for highly stressed parts. 

Aluminium 2024

Aluminum 2024 is a type of aluminium alloy, which is known for its high strength and excellent fatigue resistance.

It is primarily composed of aluminium, with copper as the primary alloying element.

The specific composition typically includes about 4.4% copper, 1.5% magnesium, and 0.6% manganese.

Aluminium 5052

Aluminum 5052 is a non-heat treatable aluminium alloy that is known for its excellent corrosion resistance. It’s a part of the 5000 series of aluminium alloys, which are primarily alloyed with magnesium.

Aluminium 5052 contains 2.5% magnesium and 0.25% chromium, which contribute to its higher strength and durability compared to pure aluminium.

It’s known for its good fatigue strength and moderate static strength. It also exhibits excellent resistance to saltwater corrosion, making it ideal for marine applications.

In conclusion, aluminium CNC services provide manufacturers with a reliable and efficient method for producing high-quality parts. Combining the inherent benefits of aluminium and the precision of CNC machining makes this a compelling option for many industries.
