What Is CNC Machined Aluminum?

CNC means Computer numerical control, Aluminum is the commonly material we machine every day,  as its perfect   machinability and ductility

Which Aluminum Is Best for CNC?

It depends your demands, 6000 series material is one of the most popular materials for CNC machining

Is CNC Aluminum Strong?

Aluminum is very common machining material, strong enough for mechanica parts, Aluminum 7075-T6 is as strong as mild steel.

Can Aluminum Be Used for CNC?

figure 1 can aluminum be used for cnc

Yes! In fact, aluminum is one of the most commonly used and machined materials by manufacturers simply because of the fact that they are cheap, they’re easy to find and source, and it is extremely machinable and weldable.

Many manufacturers consider it the Holy Grail when it comes to machining because of how easy and simple it is.

What CNC Processes Can You Use for Aluminum?

figure 2 what cnc processes can you use for aluminum

Simple – the usual and traditional manufacturing processes you do with it, you can CNC it, too. In case you require more information, the following are the most typical CNC processes that are done to aluminum in order to improve or develop it:


In the industrial sector, milling is considered one of the most common and most done processes because of the accuracy and precision that it has over other manufacturing processes. Akin to standard or regular milling, CNC milling can accurately carve, slice out, and shape the material into a shape that’s needed or wanted by the client.


Similar to milling, turning is also a great part of CNC processing. The difference it has with milling is that the toolhead or the cutting tool is the one that’s rotated and drilled against it – what this means is that the removal of the material will be extremely precise and accurate.

Plasma Cutting

Thanks to the high energy that plasma arcs have, it can pierce and slice through aluminum without any problem! Instead of slicing it, leading to a lot of crumbs on the surface, it melts away the material!

Laser Cutting

Laser cutting is similar to plasma cutting, but instead of utilizing a plasma arc, it vaporizes the material away. It’s almost similar to the process done in plasma cutting, but the difference would be in that of the energy – it uses less energy than a plasma arc.

Waterjet Cutting

Lastly, waterjet cutting is, so far, the cleanest and the neatest CNC machining process you can do to aluminum. It uses high-pressure water jets forced through a narrow nozzle, paving way for pressure and force.

These are the most common CNC processes you can use for working on an aluminum product or workpiece.

What Parts and Components Can You Produce Using by CNC Machining Aluminum?

figure 3 what parts and components can you produce using by cnc machining aluminum

CNC machined aluminum materials and products aren’t just categorized singularly. In fact, it can range from the simplest of components to the most complex! Part of these components include, but are not limited to:

  • Rods
  • Tubes
  • Plates
  • Bars
  • Wires
  • Billets
  • Sheets
  • And Many More!

CNC Machining Aluminum vs. CNC Machining Steel

figure 4 cnc machining aluminum vs. cnc machining steel

These two (2) are the most common products battled when it comes to CNC machining because of how similar, durable, resistant, and highly flexible they are. But how do they differ? How can you choose which raw product or material to use?

Here is a quick rundown of some of the best properties between CNC machining aluminum and CNC machining steel.

  • Strength-to-Weight Ratio – Aluminum is lightweight and easy to machine. It weighs only a third of steel.
  • Corrosion – Aluminum, because of its passivation layer, is corrosion resistant. However, steel is more resistant to corrosion and oxidation.
  • Thermal Conductivity – Steel has less thermal conductivity compared to aluminum.
  • Material and Machining Cost – Steel (especially stainless steel) is costlier and more expensive than aluminum. Aluminum is such a cost-effective and cost-efficient material, and it only costs ½ or 1/3 of stainless steel’s price.
  • Machinability– Aluminum is easy to cut, shape, and form. Stainless steels are generally harder and more difficult to machine and form
  • Strength – Aluminum is strong, but steel is both physically and metaphorically stronger than it. This is a true case regardless of the weight of both products.

These are some of the differences between aluminum and steel. They’re not exactly directed towards CNC machining, but these properties contribute a lot on how they can be machined and processed.  

Is CNC Machined Aluminum Strong?

Yes, CNC machined aluminum is strong – let alone standard aluminum is. If you want a more concrete and a more visualized measurement of strength, CNC machined aluminum melts at 640 degrees, it is an excellent conductor of electricity, and it is considered to have high levels of strength – that even sometimes, it can be comparable to steel.13 aluminum machining

This, of course, is something general. You can’t actually rely on it if you’re talking about raw and pure aluminum and steel.
