Compare 6061 With Other Alloys
When picking the best metal, it is good to understand how various alloys compare. 6061 aluminum is quite popular, but other alloys offer strengths for different uses. You can see its unique advantages by examining 6061 and its related alloys. This can help you choose the suitable material for your project’s needs.
6061 Vs. 6063
The two types of aluminum in the 6000 series, 6061 and 6063, are alike. They both mainly contain magnesium and silicon as alloy elements, which gives them good corrosion resistance and makes them easy to weld.
When comparing 6061 and 7075 aluminum, the key difference is their strength. 7075 is called “aircraft aluminum” since it is much stronger. This strength comes from its zinc content. However, this extra strength also makes it harder to weld and shape.
7075 is an excellent choice for aerospace needs because it is strong and light. On the other hand, 6061 is better if you need easy work with its shape and welding.

6061 Vs. 2024
2024 aluminum is much like 7075 aluminum. It is known for being very strong. This strength mainly comes from the copper added to it. The tensile strength often exceeds 65 ksi. This makes 2024 more robust than 6061 aluminum. A high level of strength is fundamental, especially when good fatigue resistance is necessary.
6061 is less resistant to corrosion and is also hard to weld. Because of this, it is a better choice when corrosion resistance and easy welding are the main factors.
Aerospace components, high-strength structural applications, aircraft fittings, gears and shafts.
6061 Vs. 5052
The main difference between 6061 and 5052 aluminum is how they react to heat. 5052 can’t be heat-treated like 6061 can. It gains its strength through cold working. Also, 5052 has more magnesium. This helps give it strong corrosion resistance, especially in water. However, 5052 does not have the same strength as 6061.
Marine environments, fuel tanks, pressure vessels, and food processing equipment.
