Many people find it difficult to choose between 2020 and 8020 aluminum for their particular use case. They usually do not know the differences in their properties which leads them to choose the wrong material and they incur loss.
In this blog post we will cover both 2020 & 8020 aluminum, their differences as well as their uses.
What is 2020 Aluminum?
2020 aluminum profile is a T slotted extrusion of 20×20 mm. It’s mostly made out of 6063-T5 aluminum. It has one open T slot on all four surfaces and those surfaces prevent dirt accumulation. You will normally find this profile in CNC machines, 3D printers and industrial structures.
What is 8020 Aluminum?
8020 aluminum profile mostly measures 80×80 mm and works as a structural framing system. Its standard T slots permit modular assembly. These high grade materials withstand heavy loads with ease. Manufacturing plants often use them in automation systems and heavy machinery where structural strength is most important.
8 Main Differences between 2020 & 8020 Aluminum
1. Flexibility & Strength
2020 aluminum achieves a yield strength of 152 MPa and a tensile strength of 214 MPa. Its robust nature makes it perfect for lightweight products such as small enclosures & frames. This profile gives less flexibility but maintains good structural stability.
8020 aluminum gives better performance with a yield strength of 214 MPa and its tensile strength reaches up to 241 MPa. Its great flexibility meets complex design requirements. These features make it a better choice for heavy duty structures.
2. Chemical Composition
The alloy composition separates these profiles. 2020 profile uses 6063-T5 alloy. In contrast 8020 uses either 6061-T6 or 6105-T5 alloy
This detailed table gives complete composition of both materials.
| Element | 2020 Aluminum | 8020 Aluminum |
|---|---|---|
| Magnesium (Mg) | 0.45-0.9% | 0.6-1.2% |
| Aluminum (Al) | 97.5-99.35% | 80% |
| Copper (Cu) | ≤ 0.1% | ≤ 0.4% |
| Iron (Fe) | ≤ 0.35% | ≤ 0.7% |
| Silicon (Si) | 0.2-0.6% | 0.4-0.8% |
| Manganese (Mn) | ≤ 0.1% | ≤ 0.15% |
3. Weight & Hardness
2020 aluminium’s Brinell Hardness is 60 HB and weighs 0.5 kg/m². Its light weight makes it an excellent choice for those engineering projects where weight savings are required.
8020 Aluminum weighs 2.1 kg/m² and has a great Brinell hardness of 95 HB. This great hardness is due to better alloy composition of this material. This feature makes it best for heavy duty industrial applications where wear resistance is very important.
4. Machinability
2020 aluminum machining process requires more cutting force due to its great strength and hardness. Tools wear out quickly when working with this material. Manufacturers must use proper lubrication and durable tools. Precision applications require post machining treatment (like stress relief) to overcome internal stress.
8020 aluminum is easily machined with low cutting force. Its soft composition greatly reduces tool wear. Manufacturers can easily create precision parts and complex designs. This material guarantees high quality surface finishes with low production costs.
5. Thermal Stability
Higher temperatures affect both aluminum profiles properties. Up to 225°C, 2020 aluminum remains stable. Above this temperature its hardness starts to decrease rapidly.
8020 aluminum performs better at higher temperatures. Its fine composition and thick walls help maintain mechanical properties under thermal stress. This stability makes it more suitable for high temperature operations and thermal stress involving applications.
6. Customization
8020 aluminum has excellent modular properties due to multiple configuration options and its large T-slot dimension. Its large cross sectional area can accommodate various accessories. With this, users can build multi dimensional structures and integrate complex frameworks. These properties make 8020 aluminum perfect for complex industrial applications that need frequent adjustments.
2020 aluminum features a simple T slot design with four open slots. This basic setting limits possibilities for customization. Its compact profile limits connection options and accessory compatibility that makes it suitable for simple infrastructure applications only.
7. Cost Comparison
Basic manufacturing process and smaller size of 2020 aluminum makes it a budget friendly choice. Its simple profile reduces tooling complexity as well as raw material requirements. This results in lower production costs for small projects.
In contrast price of 8020 aluminum is higher because of its special properties. Its material composition and large dimensions increase manufacturing costs. However industrial applications that require long term stability benefit from better durability and robustness of 8020 which justifies its additional investment.
8. Corrosion Resistance
2020 aluminum has a natural oxide layer that gives it basic protection against rust. 6063-T5 alloy composition gives standard levels of resistance to salt, moisture and pollution. Long term outdoor use may require additional surface treatment.
8020 aluminum gives better corrosion resistance due to its special alloy composition and thicker walls. It also gives great protection against environmental damage and rust. These features make it perfect for outdoor use and harsh industrial environments.
