What is 8020 Aluminum? T-slotted Aluminum Extrusion

8020 aluminum, as a special type of aluminum alloy material, is widely used in industrial and construction fields due to its unique T-shaped groove design and extrusion processing technology. This article will explore the characteristics, applications, and advantages of 8020 aluminum.

Why is it called 8020 aluminum?

Why is it called 8020 aluminum?

8020 aluminum, also known as 80/20 extruded aluminum or 80/20 framing, “8020” , which is the ratio of 80% aluminum to 20% other alloying elements. This ratio gives it excellent strength and corrosion resistance, while maintaining its relatively lightweight characteristics.

When constructing the 8020 aluminum extrusion T-groove frame, users usually choose a series of prefabricated aluminum profiles with different lengths, cross-sectional shapes, and sizes. Then, they use these profiles and T-groove accessories (such as nuts, bolts, angle brackets, etc.) to assemble the required framework. The advantages of this system lie in its ease of use, durability, and reusability.

Where does the name 80/20 come from?

The name “80/20” for the extruded aluminum stock and the company 80/20, Inc. is indeed derived from Pareto’s Law, which states that a small proportion of inputs often produces a disproportionately large result or output. The choice of this name reflects the manufacturer’s commitment to providing a product that is highly efficient and effective, with a focus on optimizing the use of materials and effort.

80/20, Inc. was founded in 1989 and named after the economic principle to emphasize the company’s dedication to creating aluminum extrusions that offer maximum performance and value. The company’s products are designed to provide strong, lightweight, and cost-effective solutions for a wide range of applications, from industrial automation to consumer products.

By naming their products and company after Pareto’s Law, 80/20, Inc. is symbolically expressing their belief that a small percentage of their efforts (the 20%) will yield the majority of the benefits (the 80%) for their customers. This naming convention has become synonymous with the company and its products, making “80/20” a recognizable brand name in the aluminum extrusion industry.

How strong is 8020 aluminum extrusion?

The strength of 8020 aluminum extrusion is primarily determined by the alloy composition, tempering process, and geometrical characteristics of the extruded profiles. Aluminum alloys commonly utilized in 8020 extrusions, such as 6061 and 6063, are renowned for their excellent mechanical properties, including high tensile strength and yield strength.

The strength of 8020 aluminum extrusion can be further augmented through appropriate heat treatment methods, such as solution heat treatment followed by quenching and aging. These processes refine the microstructure of the alloy, enhancing its mechanical properties and overall strength.

The design of the extruded profile also plays a critical role in determining its strength characteristics. Factors such as wall thickness, cross-sectional geometry, and the presence of reinforcing features influence the structural integrity and load-bearing capacity of the extrusion.

Sensitivity to the environment: Although the aluminum alloy itself has good corrosion resistance to most environmental conditions, it may be affected under certain extreme environmental conditions (such as high humidity, high salinity, etc.).

Limited strength and stiffness: Although aluminum alloy has high strength and stiffness, it may not be the best choice in some applications that require extremely high strength and stiffness.

What is the difference between extruded aluminum T-slot and V-slot?

Extruded aluminum T-slot and V-slot are two different types of profiles commonly used in modular framing systems. They differ primarily in their cross-sectional shape and how they are designed to work with components and accessories.

What is the difference between extruded aluminum T-slot and V-slot

T-Slot aluminum extrusion:

T-slot aluminum extrusions have a cross-sectional shape that resembles a letter “T.” This shape creates a track or slot that runs along the length of the extrusion, allowing for the insertion of T-nuts or other compatible fasteners. These fasteners can then be tightened to securely hold components in place within the frame.

T-slot aluminum extrusions are popular in industrial applications because they offer a strong and rigid structure that can be easily customized. The T-slot design allows for quick and easy assembly, disassembly, and modification of frames. It is also compatible with a wide range of accessories, brackets, and connectors, making it a versatile framing solution.

V-Slot aluminum extrusion:

V-slot aluminum extrusions have a cross-sectional shape that resembles a letter “V.” This design creates a groove or slot that runs along the length of the extrusion, allowing for the insertion of compatible components, such as clamps or brackets, without the need for fasteners.

V-slot aluminum extrusions are becoming increasingly popular in robotics, automation, and other DIY applications. They offer a lighter and more cost-effective framing solution compared to T-slot extrusions. The V-slot design allows for quick and easy assembly of frames without the need for tools or fasteners, making it suitable for hobbyists and DIY enthusiasts. However, it may not offer the same level of strength and rigidity as T-slot extrusions.

When was 8020 aluminum invented?

The 80/20 framing system was invented by 80/20 Inc., a company founded in 1989 by Don Wood and Bob Kyanka. They introduced the concept of using T-slot aluminum extrusions with a modular design, allowing users to easily assemble and reconfigure structures without the need for welding or specialized tools. Since its introduction, the 80/20 framing system has gained widespread popularity due to its versatility, durability, and ease of customization.

What is the difference between regular aluminum and extruded aluminum?

The main difference between ordinary aluminum and extruded aluminum lies in their manufacturing process and ultimate use.
Ordinary aluminum usually refers to pure aluminum or aluminum alloys that have not been further processed. It can exist in the form of casting or rolling, with basic metal properties such as good conductivity and thermal conductivity, as well as certain strength and plasticity.
Extruded aluminum refers to aluminum material processed through extrusion technology. Extrusion is a forming process in which aluminum billets are heated to a plastic state and then forced to deform through molds to form aluminum materials with specific shapes and sizes.

Can you cut 8020 aluminum?

Yes, 8020 aluminum can be cut.
When cutting 8020 aluminum, it’s important to use the right tools and techniques to ensure clean, precise cuts. It’s also advisable to wear protective gear, such as safety glasses and gloves, to prevent injuries. Additionally, it’s crucial to follow the manufacturer’s recommendations and guidelines for cutting and modifying 8020 aluminum to ensure the best results and maintain the integrity of the material.

What is the difference between 10 series and 15 series 8020?

The main difference between the 10 series and 15 series of 8020 aluminum extrusions is their dimensions and strength capabilities.
The 10 series of 8020 aluminum extrusions typically refers to the standard extrusions that are 80mm wide and 20mm tall. These extrusions are designed for light-duty applications and can be easily cut, drilled, and machined to create custom frames and structures.
The 15 series of 8020 aluminum extrusions, on the other hand, are thicker and stronger than the 10 series. They are typically 80mm wide and 30mm tall, providing additional strength and rigidity for heavier-duty applications. These extrusions are often used in industrial and commercial applications that require a more robust framing solution, such as in equipment that needs to support heavier loads or withstand more rigorous environments.
