However, when comparing apples to apples (same grade and thickness), Aluminum 6061 will usually be cheaper than Aluminum 2024.

With either option, you can experience the superior performance and durability of aluminum without stretching your budget too far.


Weldability of aluminum

Examining the weldability of Aluminum 2024 and 6061 can help determine which is better suited for your project.

When it comes to welding, Aluminum 2024 is more challenging than 6061. This is because while both alloys are heat treatable, 2024 is an aluminum-copper alloy with copper concentrations that can cause cracking during welding.

Meanwhile, 6061 has a lower rate of thermal expansion and greater toughness than 2024. Additionally, as an aluminum-magnesium-silicon alloy, 6061 offers superior corrosion resistance compared to 2024.

Making it ideal for projects where strength and corrosion resistance are paramount. Ultimately, those looking to weld should keep in mind that 6061 offers greater ease when compared to its counterpart.


By comparing weldability, thermal expansion, toughness, and corrosion resistance, it's clear that 6061 is the superior alloy for projects where strength and durability are essential.

With its high-strength welds, low coefficient of thermal expansion, excellent fatigue resistance, and great corrosion resistance, you can count on 6061 to get the job done right every time!

It's the perfect alloy for your next project if you're in search of a reliable material with consistent results—all without having to worry about sacrificing any quality or safety standards.

With 6061 aluminum, you'll have peace of mind knowing your work will stand up to any test while also providing an attractive finished product that will make you proud.
