3003 Aluminum

An all-purpose alloy for general applications

Manganese is the main alloy element, making 3000 series aluminum an excellent all-purpose alloy with moderate-strength and strong corrosion resistance.

This aluminum metal receives a good rating for machinability, welding, brazing, and forming applications, but is not heat treatable and soldering can only be performed by torch.

Frequently Asked Questions (FAQs)

What are the characteristics of 3003 aluminum vs. 6061 aluminum?

6061 and 3003 are two of the most common aluminum alloys available, and many consider them interchangeable. However, each offers unique mechanical values which help determine which would be preferable for a particular application. 6061 has a greater yield strength than 3003, whereas 3003 aluminum has better formability and a lower shear strength, making it easier to cut. 3003 aluminum is the better choice in forming applications.

What are the characteristics of 3003 vs. 5052 aluminum?

5052 and 3003 aluminum are both common aluminum alloys with similar characteristics, including corrosion resistance. 5052 is stronger and more corrosion-resistant, while 3003 is easier to work and form, offering solid corrosion resistance and strength.

What is 3003 aluminum’s density?

3003 aluminum alloy’s density is 0.0986 lb/in3.

How machinable is 3003 aluminum?

3003 aluminum is fairly machinable, but it falls short compared to other aluminum alloys such as 6061 or 5052 due to its mechanical properties and other attributes, such as weldability.
