How Does Aluminum Extrusion Work?

Aluminum extrusion refers to a process to manufacture parts with a specific cross-sectional profile by pushing heated aluminum alloy material through a mold. Simple understand, it is similar to squeezing toothpaste from a tube.

Which Types of Shapes Can be Extruded?

Aluminium sheet tube

General speaking, three main categories of extruded shapes are available in aluminum extrusion:

  • Solid part that has no enclosed voids or openings. Such as rod, beam or angle.
  • Hollow part that has one or more voids. Such as square or rectangular tube.
  • Semi-hollow part that has partially enclosed void. Such as a “C” channel with a narrow gap.

In a word, the shapes created can be solid, hollow and semi-hollow; they can be simple or complex. And we provide the customized services for your parts.

The Benefits of Aluminum Extrusion

  • Versatile and relatively low cost.
  • High strength-to-weight ratio and possesses non-corrosive properties.
  • Eco-friendly.
  • Accept high performance coatings.

Application Field of Aluminum Extrusion

Aluminum extrusion has a wide applicance in architectural, automotive, aerospace, electronics, energy industries and others.

Usually, aluminum extrusion parts are recommended to do surface finish due to below two reasons:

  • Finishes can enhance the appearance.
  • Finishes can improve corrosion resistance and protect the surface from being anodized.

What’s Types of Surface Finish Can NICE Rapid offer?

There are some common surface finishes we can offer:

  • Anodization
  • Mechanical finishes
  • Powder coating
  • Sublimation
  • Mirror Surface




This is a special electrochemical finish that can provide additional protection aside from the natural oxide film. And the parts can be colored according to your requirements.

Mechanical finishes

There are series of mechanical finishes such as blasted, polished, sanded and grinded can be improved for surface quality or other cosmetic requirements.

Powder coating

This is also a chemical finish that provide a film to meet stringent performance criteria. The coating is thick and bonds to the aluminum, it doesn’t chip or peel easily. The most important, it has no solvents or VOCs (Volatile Organic Compounds), eco-friendly.


This is absolutely a magic experience for some people that see the aluminum extrusion look like wood. Yes, sure it is sublimation that after applying a base coat of powder. And the sublimation process transfers that pattern directly onto the extrusions according to customer’s requires.

Mirror surface

In order to give the aluminum a specular or “mirror” finish, we need to put the profile into a special dip solution (a combination of hot phosphoric and nitric acids). The aluminum parts can be anodized as well.
