CNC (Computer Numerical Control) aluminum extrusions are versatile materials that offer a wide range of possibilities for industrial design and manufacturing. By manipulating the extrusion process using computer-controlled machinery, manufacturers can produce complex shapes and intricate designs with high precision and repeatability. This article explores the different types of CNC aluminum extrusions available, highlighting their unique characteristics and applications.

Solid Extrusions

Solid extrusions are the most basic type of CNC aluminum extrusion. They are typically used in applications where strength and rigidity are essential. Solid extrusions come in a variety of shapes, including round, square, rectangular, and hexagonal. They can also be customized with additional features such as grooves, slots, and holes.

Hollow Extrusions

Hollow extrusions are similar to solid extrusions but with a hollow core. This makes them lighter and more cost-effective than solid extrusions while still providing excellent strength and rigidity. Hollow extrusions are often used in applications where weight reduction is important, such as aerospace and transportation.

Complex Extrusions

Complex extrusions are made using multiple passes through the extrusion press. This allows for the creation of intricate shapes and profiles that would be impossible to achieve with a single extrusion. Complex extrusions are often used in applications where aesthetics and functionality are equally important, such as furniture and architectural components.

Applications of CNC Aluminum Extrusions

The applications of CNC aluminum extrusions are vast and varied. Some of the most common include:

Automotive: Frames, bumpers, and other components

Aerospace: Wings, fuselages, and other structural parts

Construction: Windows, doors, and other architectural elements

Electronics: Heat sinks, enclosures, and other components

Furniture: Legs, frames, and other components


CNC aluminum extrusions are a versatile and efficient way to produce complex shapes and intricate designs with high precision and repeatability. By understanding the different types of extrusions available, designers and manufacturers can select the ideal material for their specific application, ensuring optimal performance and cost-effectiveness.
