Common Questions About 8020 Aluminum CNC Machining Parts

 

 

Why is it called 80/20 Aluminum?

The name "80/20" originates from its design philosophy and proportional relationship. In some cases, it might refer to the profile's sectional size ratio (such as 80mm wide and 20mm high), but more broadly, it represents concepts like "80% performance at 20% cost" or "80% efficiency with 20% effort," emphasizing a good balance between performance and economy.

 

 

What is the best grade of aluminum for extrusion?

The best grade of aluminum for extrusion depends on specific application requirements. While 8020 aluminum is a common extrusion aluminum alloy, there are many other grades to choose from, such as 6061 and 6063. The best grade is chosen by considering factors like material strength, corrosion resistance, machinability, and cost.

 

 

What is the difference between 10 Series and 15 Series 8020 Aluminum?

"10 Series" and "15 Series" might refer to different series or specifications of 8020 aluminum profiles. There isn't a standard differentiation of "10 Series" and "15 Series" for 8020 aluminum profiles. This terminology might be specific to a manufacturer or brand's product classification. Generally, the differences would be in profile dimensions, wall thickness, material composition, mechanical properties, or surface treatment.

 

 

What is the yield strength of 80/20 Aluminum?

The yield strength of 80/20 (or 8020) aluminum is not a fixed value as it may vary depending on the specific alloy composition, heat treatment state, and manufacturer. Generally, 8020 aluminum, as a structural aluminum alloy, has high yield strength, but specific values need to be referenced from relevant material datasheets or the supplier.

 

 

Does extruded aluminum rust?

Extruded aluminum (including 8020 aluminum) does not rust because aluminum is a highly reactive metal that forms a dense oxide layer in the natural environment. This oxide layer effectively protects the aluminum substrate from further oxidation or corrosion. However, if the surface of the aluminum is scratched, abraded, or exposed to extreme environments (such as strong acids or bases), the protective layer may be damaged, leading to corrosion. Therefore, it is important to protect the aluminum surface in applications and choose appropriate surface treatments to enhance its corrosion resistance.

 

 

What is the difference between aluminum and extruded aluminum?

Aluminum is a metallic element characterized by its light weight, good conductivity, good thermal conductivity, and corrosion resistance, and is widely used in various fields. Extruded aluminum refers to aluminum that has been processed and formed through the extrusion process, including various shapes of profiles, tubes, rods, etc. The extrusion process can give aluminum specific shapes and dimensions while enhancing its strength and hardness. Therefore, extruded aluminum is a processed form of aluminum with higher machining precision and better mechanical properties. Unprocessed aluminum (such as aluminum ingots, aluminum plates) requires further processing to meet specific application requirements.

 

 

 

Conclusion

 

In conclusion, 8020 aluminum, as a high-performance extrusion aluminum alloy material, has broad application prospects in the field of CNC machining parts manufacturing. By understanding its characteristics, selecting the appropriate machining processes and material specifications, its advantages can be fully utilized to meet various complex and customized needs.
