Is Aluminum Good for CNC Projects – Best Routers (2023)

Aluminum is a unique type of metal found in many structures. While steel is the most common one in manufacturing, aluminum has many applications due to its high strength/weight ratio and relatively low cost. 

Why a CNC Router that Cuts Aluminum is a Great Investment?

When it comes to CNC, it’s favorable to use aluminum over steel because the cost of the equipment increases for cutting harder metals like steel. So, it’s a cheaper option to acquire a machine that cuts only relatively soft metals such as aluminum. Here is why.

CNC routers are known for cutting or carving materials that are not hard. A big part of the market focuses almost entirely on wood and plastic. However, it’s not uncommon for them to face a problem that can easily be solved using metals. Thus, many people make a pretty common question on such an occasion, can we use this machine for metal cutting? 

Well, it depends. The machines that can cut steel are at a higher price level compared to the ones that cut wood or plastic. So, using steel on low powered units is a bad idea. 

However, the price of a unit that can cut soft metals such as aluminum is almost the same as the price of a unit suitable for non-metallic manufacturing. So, it’s a wise option to buy a machine ideal for both metallic and non-metallic objects. 

What are the Best CNC Machines for Cutting Aluminum?

Considering the facts described above, I have created a list of value for money CNC machines for cutting aluminum. This way, you will utilize the full potential of every penny that you are paying. I have included some units for cutting or engraving even harder metals than aluminum like steel in the list below. Here is the top best CNC machine for aluminum.

Beginner Friendly CNC Machines for Aluminum

I know that some of you are taking your first steps into CNC machining. Therefore, starting small is essential if you don’t have someone with experience. If that’s your case, I would recommend Genmitsu CNC 3018-PRO Router Kit or Benbox CNC Router. Those machines would be excellent choices for hobbyists or beginners.


I have listed several machines that can help you achieve any type of project. I am confident that you will find one with all the features you need without overpaying those you don’t need. Now, let’s talk more about CNC applications on aluminum.

Is Aluminum a Good Material for CNC Projects

For CNC machining tasks or projects, aluminum is a common choice because of its desirable physical properties. So, using aluminum for CNC projects is often favorable. Let’s find out why.

Why Aluminum is a Great Choice for CNC Projects

You might be wondering why aluminum is so popular among CNC machinists. Well, aluminum can be cast, melted, formed like the other metals. However, what makes the use of aluminum widespread are the following factors.

Excellent Machinability: Unlike other metals with the same properties, aluminum provides superb machinability. Many of its grades can be penetrated efficiently by your cutting tools, and they chip easily, whereas being comfortable to form and shape. It can be machined over three times faster compared to steel and iron. 

This metal is available in many various alloys, each one with slightly different properties. Thus, some alloys might be easier to shape, mill as well as cut. 

Some of them are too soft and can be hard to work with. As a matter of fact, it might create a gummy buildup once machined or cut close to its melting temperature. 

Considerable Strength: It’s a tough and strong element that gives unique mechanical properties to parts. It might be less strong than steel but still, engineers design structures where aluminum pieces face tremendous stresses and tensions.

Lightweight: This is a super lightweight metal only weighs 2.7 g/cm3. It has many applications like in cars to reduce dead weight. In many cases, aluminum alloys have a better strength/weight ratio than steel. 

Corrosion Resistance: A significant difference between steel and aluminum is that aluminum has a corrosion-resistant oxidized outer layer. As we know, rust doesn’t stop oxygen molecules from destroying steel. On the other hand, aluminum is a metal that naturally produces a protective thin oxide coating that keeps it from making more contact with the corrosive oxygen. It is valuable for applications where it is exposed to corroding substances, as in cars and shipbuilding. That’s a fundamental reason why CNC machinists choose this metal for their projects.

Thermal and Electrical Conductivity: This is a great electricity and heat conductor. Comparing it with copper, for the same weight, aluminum is virtually twice as good a conductor as copper. This is the reason why it is the first choice for power transmission lines where the conductivity/weight ratio must be high.

Ductility: This metal is also ductile and has a low melting density and point. Aluminum can be processed in many ways in a molten state. That’s another critical reason why CNC machinists use it on many structures. It’s a less stiff material that is easy to cut.

Non-magnetic: This is a non-magnetic metal, making it valuable for electrical shielding as in computer disks, busbars, and dish antennas. Creating panels for those objects are some of the most common applications of CNC Machines.

Which Types of Aluminum are Perfect for CNC Projects?

Knowing the best metal for CNC machining can be an overwhelming and challenging task. Most of the time, it will be easy to determine which metal’s alloy is better to use.

Many factors have to be considered when choosing a material for a product or part, including the price, strength, workability, corrosion, weight, and cosmetic appearance. When it comes to aluminum, there are lots of alloys and metals which can be utilized for CNC machining. Let us review the most useful ones and the reasons behind our pick.

Aluminum 6061: This type of aluminum comes with exceptional mechanical properties as well as superb weldability. Because of its high strength, toughness, and super corrosion resistance in harsh conditions, it’s a very useful alloy. Aluminum 6061 is popularly utilized in five-axis CNC machining. 

Aluminum 7075: Another popular alloy renowned for its superb fatigue strength is the 7075. However, keep in mind that 7075 isn’t ideal for welding. Therefore, it is perfect for tough parts like bicycle parts, fuselages, aircraft wings, and rock climbing kits. So, it’s pretty much evident that there is an extended usage of it on CNC projects.

Aluminum 2024: This alloy has an enormous amount of applications in the aerospace and military sector. Let’s see the reasons why it is a great choice in those industries. It’s possible due to its mechanical properties, such as high strength and remarkable weariness resistance. However, it has low corrosion resistance, and it’s not weldable. 

It has low hardness and high thermal expansion. It can be easily deformed once machined into a thin part. Despite that, there are vital steps that must be followed to stop the material’s deformation in advance. 

What Type of CNC Machines Is Mostly Used on Aluminum?

A common question that you might have is how commonly the various types of CNC technology are used for tasks on aluminum. Actually, the use of it is similar to most machine types. Most aluminum related projects have to do with the following CNC machine types.

CNC Routers: That was pretty obvious if you are familiar with the industry. Routers perform excellently on aluminum.

Plasma Cutters: A type of machine which utilizes plasma torches to cut through metal effectively. The device’s accuracy makes it a number one choice because it just melts the area you are working on. 

Laser Cutters: On those CNC machines, laser beams are used to cut through aluminum. 

Milling Machines: Such a machine allows you to drill and trim parts to make components and precision parts. CNC milling machines are used all over the world for different industrial and manufacturing needs. It is ideal for CNC cutting tools because you can perform many tasks like shoulder and face milling, drilling, tapping, and turning. 

Final Thoughts

Before closing, I would like to mention some of my thoughts. CNC has to do a lot with experimenting on new designs and materials. The key idea is to have a CNC machine that doesn’t stop you from becoming better at CNC due to its limited capabilities. However, you don’t want to overspend by buying specs that you don’t need. So basically, you want a machine that can perform slightly more difficult tasks than you are expecting to have.

I hope that you have found great value in this article. You can read more about CNC in other articles on my website.
