Harnessing the Strength and Flexibility of 4040 Extruded Aluminum

Harnessing the Strength and Flexibility of 4040 Extruded Aluminum

4040 extruded aluminum is also known as 4040 aluminum profile. Its size is 40mmX40mm. Its external surface is smooth and flat without obvious bumps or scratches.

It is a high-quality aluminum alloy with excellent strength characteristics, processability and corrosion resistance.


4040 extruded aluminum is a high-quality aluminum alloy material. It is mainly composed of aluminum and some alloy elements (including copper, manganese, magnesium, etc.) With these elements together, it can improve the strength, hardness, and corrosion resistance of aluminum. Its finish is generally anodized. So it can increase the corrosion resistance and hardness of 4040 extruded aluminum. And this will make it more durable.

In summary, the characteristics of 4040 extruded aluminum are pleasing to the eye, durability, corrosion resistance and high strength.


In addition, it also has the characteristics as below:

Lightweight and easy to install.

4040 extruded aluminum is lightweight and this can save transportation costs. It is modular in design. So it is simple and convenient to install without special tools and skills. This can shorten the installation time.

Strong flexibility.

We can customize 4040 aluminum with different specifications, shapes, and sizes according to customer needs to meet various production needs. And this can easily solve various complex problems and optimize production processes.

Environmental protection and conservation.

The 4040 extruded aluminum can be reused multiple times. It is a recyclable material.


Because of so many advantages of 4040 aluminum series, their specifications, wall thicknesses, and theoretical weights are all diverse.



There are up to 15 specifications in 4040 aluminum series. The sectional shapes of 4040 aluminum series are square, rectangle, single radius, angled, triangular, L shape, L shape with radius and so on. With so many different specifications, people have more choices for different purposes.

More sectional shapes for 4040 aluminum are shown in the picture below.


Wall thickness

There are also many wall thicknesses for 4040 aluminum series, such as 1.5mm, 1.8mm, 2mm, 2.5mm, 3mm, 3.2mm, etc. Different wall thicknesses have different bearing capacities. People can choose them according to their different needs.


Weight per meter (Theoretical weight)

Because the sectional shape and wall thickness for each 4040 extruded aluminum are different from others, so its weight per meter is also different. The range is from 1.03kg/m to 3.2kg/m. The weight per meter directly affects the load-bearing capacity of the 4040 aluminum. People can pick up the 4040 aluminum with thinner wall thickness for line frame structures with less load-bearing requirements; conversely, pick up the one with thicker wall thickness. And this can greatly save costs and expenses for users.

Therefore, this is the reason that the 4040 aluminum profile is deeply loved by people.
