How strong is 2020 Aluminum Extrusion?
When looking for strength in 2020 aluminum extrusions, this profile is a popular choice for many applications. 20 x 20 mm in size, this T-slot aluminum extrusion has high tensile and bending strength. Tensile strength is usually between 230-270 MPa, good for building frames, equipment supports, and more.
In this article, we will look at the strength characteristics of 2020 aluminum extrusions, load-bearing capacity, and mechanical properties. We will also compare it to other aluminum profiles to highlight the benefits. Knowing the strength of 2020 aluminum extrusion will help you make informed decisions for your projects, whether you are designing a workspace or building machinery.
What Does 2020 Mean?
The term “2020” refers to a T-slot aluminum extrusion that measures 20 x 20 mm. It has four main open T-slots, one for each 40 mm phase. This series includes profiles such as 20 x 80, 20 x 20RQ, 20 x 60, and 20 x 40.
The 2020 aluminum extrusion is strong and suitable for building frames, platform supports, and equipment. Its strength comes from several key factors, which we will discuss next.

Alloy Type and Strength Criteria
The yield stress of 2020 aluminum extrusion is typically around 215 MPa. When the stress exceeds this level, the aluminum begins to deform plastically, resulting in permanent changes to its shape.
The common alloys used for this extrusion are 6061-T6 and 6063-T5. These alloys provide higher strength and stress resistance compared to standard architectural aluminum extrusions.
Calculation of Load-Bearing Capacity
The load-bearing capacity of aluminum profiles depends on their cross-section size, wall thickness, length, and tensile strength. You can calculate the load-bearing capacity (P) using this formula:
P=0.44×(D+t)×L×σb
In this formula:
- D is the section diameter,
- t is the wall thickness,
- L is the length,
- σb is the tensile strength.
This equation helps you determine how much weight the aluminum profile can support based on its dimensions and material properties. Understanding this calculation is essential for ensuring that your projects are safe and effective.
Other Mechanical Properties
Aluminum profiles have important mechanical properties beyond strength and load-bearing capacity. These include elongation and hardness.
- Tensile Strength: The tensile strength of the 2020 aluminum extrusion ranges from 230 to 270 MPa.
- Bending Strength: The bending strength typically falls between 150 and 180 MPa.
These properties affect how aluminum performs in various applications. Knowing these characteristics helps you choose the right material for your project.
Connection Method
The 2020 aluminum extrusion connects using M5 or M4 T-nuts and hexagonal bolts. M5 T-nuts are the standard choice for most applications. For projects requiring extra strength, use 20 series slider nuts with hexagonal bolts. This method creates a strong and reliable connection.
To assemble, insert the T-nut into the extrusion slot, align it with the hole, and tighten it with a bolt. This process is simple and does not need special tools. The connection is secure, making it suitable for various structural uses.
2020 vs. 8020 Aluminum Extrusions
The main difference between 2020 and 8020 aluminum extrusions is their size and load-bearing capacity.
The 2020 profile measures 20 x 20 mm. It is compact and cost-effective, making it suitable for lightweight projects. This profile provides enough strength for moderate loads, ideal for applications like electronics and robotics.
The 8020 profile measures 80 x 80 mm. It offers larger dimensions and greater structural strength. This makes it better for heavy-duty applications that require higher load-bearing capacity.
Choosing between the two profiles depends on your project needs. Use 2020 for lightweight applications and select 8020 for projects that need more strength and stability. Each profile has its benefits, so assess your requirements to make the best choice.
Final Thoughts
The strength of the 2020 aluminum extrusion is significant. It meets most building and framing standards, making it suitable for various applications. Compared to other aluminum extrusions, 2020 offers reliable performance and durability. This material provides the strength needed for constructing frames and supporting equipment.
