If you are looking for a hard and flexible material, 8020 aluminum alloys are a possible option. This blog describes the main benefits of 8020 aluminum alloys in the industry and emphasizes why it is a favorite resource in aviation, production, industrial equipment design, and product design.
Overview of 8020 Aluminum Alloy
8020 Aluminum means an extruded aluminum alloy usually from the 6000 series. It is used in modular frames and supports. You can use it for crafting personal workstations, safeguards for the machines, display units for exhibits, and structural parts for industrial settings. People call it after the 80/20 brand, which supplies T-slot aluminum profiles that make it easy to assemble structures.
Its powerful strength-to-weight ratio, resistance against corrosion, and adaptable properties allow you to work fast. If you are an engineer or part of procurement, this material enables you to build a solution that can be reused and is budget-friendly for various automation and manufacturing applications.

Mechanical Properties
| Properties | Tensile Strength | Yield Strength | Elongation | Hardness | Modulus of Elasticity |
| Attributes | 230–280 MPa | 200–250 MPa | 8–12% | 70–80 HB | 69 GPa |
o Tensile Strength
The strength of the 8020 aluminum gives your structures a tensile strength of 230–280 MPa, making them survive major pulling forces before breaking.
o Yield Strength
The reliable yield strength is 200–250 MPa; the alloy will not easily deform under stress, and it is therefore great for heavy use and important parts.
o Elongation
With an 8-12% elongation rate, 8020 Aluminum is not rigid but bends slightly without breaking, making it great for absorbing dynamic or impact loads.
o Hardness
The hardness rating of 70–80 HB for 8020 Aluminum allows it to resist wear. This will help you maintain durability and surface integrity over time.
o Modulus of Elasticity
8020 Aluminum has an elastic modulus of about 69 GPa, which makes your structures stiff enough to keep their shape and also gives some flexibility.

| Properties | Density | Melting Point | Thermal Conductivity | Electrical Conductivity | Thermal Expansion |
| Attributes | 2.70 g/cm³ | 660°C | 167 W/m·K | 43% IACS | 23.1 µm/m·K |
o Density
8020 Aluminum at 2.70 g/cm³ is both lightweight and sturdy, which can make your products less heavy without jeopardizing their structure.
o Melting Point
Aluminum 8020 has a melting point of 660°C, which helps it remain easy to use and reuse, so it’s useful for high-heat settings in industries.
o Thermal Conductivity
Being a highly effective conductor, 8020 Aluminum ensures that heat is efficiently dealt with in machinery and heat-dissipating components, by having a high thermal conductivity of 167 W/m·K.
o Electrical Conductivity
At a 43% IACS rating, this alloy transfers electricity well enough for moderate electrical use in mechanical or automation systems.
o Thermal Expansion
When your objects change temperature, this alloy resists warping or loss of size due to its thermal expansion rate of 23.1 µm/m·K.
Heat Treatment and Other Processing Techniques
- Heat Treatment
You can heat 8020 aluminum to make it stronger and harder by increasing its mechanical properties. This method improves performance in difficult situations without changing form.
- Extrusion
Most often, 8020 Aluminum is produced by extrusion, resulting in very tight T-slot profiles. It is easy to customize, is quickly placed together, and ensures frequent quality in your structural and modular systems.
- Forging
Though it is not commonly forged, you can use 8020 Aluminum in low-pressure forging for particular purposes. This material is dominant and strong, which allows designers to create flexible, lightweight parts.
Surface treatment, such as Anodizing or powder coating the metal surface, can make it more resistant to corrosion and more attractive. This makes your 8020 Aluminum alloy structures stronger and long-lasting.
Conclusion
8020 aluminum alloys stand as a smart, reliable alternative for alloy builders, designers, and engineers. Its strength, flexibility, and ease of use make it ideal for countless applications. Hmaking helps to bring your ideas to life with efficiency and confidence, whether you create prototypes or make industrial systems.
