4040 Aluminum Extrusion Dimensions and Specifications

The size and specification of 4040 aluminum extrusion can be detailed as follows:

1. basic size: 40mm × 40mm (i.e. width and height are 40mm).
2. Thickness range: the thickness of 4040 aluminum extrusion ranges from 1.5mm to 10mm.

Different thicknesses of 4040 aluminum are suitable for different application scenarios. Generally speaking, thinner aluminum extrusions are suitable for lightweight structures, while thicker aluminum profiles are suitable for structures that are subject to higher loads.

3. Common specifications:

Wall thickness: common wall thicknesses are 1.5mm, 1.8mm, 2mm, 2.5mm, 3mm, 3.2mm, etc.
Slot width: there are slot 8mm and slot 10mm specifications.

4. Example dimensions (from Hugh Aluminum products)

 

HF-8-4040S-F:

• Length: 6m (can be cut on demand)
• Slot width: 8.2mm
• Surface treatment: anodized silver white, powder coated silver. (Surface can be customized)

 

HF-8-4080E-M:

• Unit mass: 2.307kg/m(HF-8-4080E)     2.392kg/m(HF-8-4080M)
• Length: 6m (cut to size)
•  Wall thickness: 1.5mm
•  Slot width: 8.2mm
• Surface treatment: mill finish or powder coating (surface can be customized)

Its applications:

4040 aluminum extrusion is widely used in industry, construction, transportation and other fields because of its high strength, good corrosion resistance and excellent thermal conductivity.

Especially it is used for frame combination structure with relatively high strength, such as equipment frames, assembly line operating tables, automation equipment, etc. It can also be used as display racks or fish tank frames in homes.

Surface treatment:

The common surface treatment is anodic oxidation treatment, which is not only beautiful and strong, but also has strong corrosion resistance. However, some products may be used in seawater environment or humid environment, so you can choose powder coating. This surface treatment can protect it from erosion.

Summary:

The standard size of 4040 aluminum extrusion would be 40×40, and aluminum with 8mm slot width. It can be customized in size and length. It is adjusted according to the customer’s building project.
