Aluminum Alloy 3105 Data Sheet

ALUMINUM ALLOY 3105 GENERAL DESCRIPTION :

What is Alloy 3105?

The 3105 aluminum alloy offers higher strength than 3003 aluminum. It’s characterized by excellent formability, corrosion resistance, and good weldability, but is not heat-treatable. Commonly used in sign making, residential siding, and sheet metal work, it’s known for its good anti-rust properties and conductivity.

FAQs

What is the Difference Between 3003 and 3105 Aluminum?

The primary difference between 3003 and 3105 aluminum is their composition and strength. 3003 aluminum contains only manganese as its main alloying element, providing good formability and corrosion resistance. On the other hand, 3105 aluminum includes both manganese and magnesium, giving it a slight strength advantage over 3003 aluminum.

What is the Difference Between 5052 and 3105 Aluminum?

The main difference between 5052 and 3105 aluminum lies in their composition and mechanical properties. 5052 aluminum is alloyed with magnesium and chromium, which provides higher strength and excellent corrosion resistance. In contrast, 3105 aluminum is alloyed with manganese and magnesium, offering moderate strength and good corrosion resistance, but not to the same extent as 5052.
