2020 aluminum extrusion (T-Slot Extrusion) is a profile made to European standards. It measures 20 mm × 20 mm in cross-section. The profile features trapezoidal grooves, and its edges have rounded transitions for safety and aesthetics.

This profile is created by extruding aluminum, which shapes the metal into the desired form. The 2020 aluminum extrusion can be anodized to add color and improve its surface finish. It is lightweight yet strong, making it suitable for various applications in automation, machinery, and construction. Its design allows for easy assembly with other components, providing flexibility for different projects.

How to Join 2020 Aluminum Extrusions?

Connecting aluminum extrusions 2020 is simple and effective. Use M5 or M4 T-nuts with hexagonal bolts for internal connections. Most projects will use M5 T-nuts, while M4 nuts are suitable for lighter loads.

For applications that need more strength, use 20 series slider nuts with hexagonal bolts. This method creates a strong connection.

Follow these steps to join the extrusions:

  1. Insert the T-nut into the slot of the extrusion.
  2. Align the T-nut with the desired hole.
  3. Tighten the bolt using a hex key until secure.

This process is quick and requires no special tools. The connection is durable, making it ideal for various applications in automation, construction, and more.

Advantages of 2020 Aluminum Extrusion

Lightweight

The density of aluminum is about one-third that of steel, making 2020 aluminum lightweight. This feature allows for easy handling and installation, reducing the overall weight of equipment and structures. It is a popular choice for many frames.

Corrosion Resistance

2020 aluminum extrusion resists corrosion effectively. In oxidizing environments, it forms a protective aluminum oxide film that shields the metal underneath. This property extends the service life of 2020 aluminum in outdoor, humid, or corrosive conditions.

High Strength

Despite its low density, the aluminum extrusion 2020 offers high strength. Through careful alloying and heat treatment, it achieves the necessary strength for applications like workbenches, stages, and equipment frames. This makes it suitable for demanding environments while remaining lightweight.

These advantages make 2020 aluminum extrusion a versatile choice for various applications, combining strength and durability with ease of use.

The Disadvantages of 2020 Aluminum Extrusions

  1. Limited Load-Bearing Capacity: While 2020 aluminum has high strength, its load-bearing capacity is limited. It may not support heavy equipment or structures.
  2. Higher Price: The manufacturing process and materials for 2020 aluminum can be costly. This higher price may increase the overall project budget.
  3. Special Groove Type: The trapezoidal groove design requires specific connectors and nuts for assembly. This can complicate installation and maintenance, raising costs.

Applications of 2020 Aluminum Extrusion

  1. Small Cabinets and Workbenches: 2020 aluminum extrusion is ideal for small cabinets, workbenches, and whiteboard racks. It combines style with practicality.
  2. Machine Covers and Instrument Racks: Its structural features make it suitable for lightweight frame assemblies, such as machine covers and instrument racks.
  3. Solar Photovoltaic Racking: 2020 aluminum is commonly used in solar photovoltaic racking systems. Its design adds stability and durability in outdoor settings.

Final Thoughts

2020 aluminum profiles have several advantages. They are lightweight, resist corrosion, and provide high strength. However, they also have drawbacks. Their load-bearing capacity is limited, they tend to be more expensive, and they require special connectors due to their groove type.

When selecting 2020 aluminum profiles, consider your specific needs and project context. Evaluating these factors will help you decide if the 2020 aluminum extrusion is the right choice for your application.
