The 3000 series aluminum alloys mix aluminum with manganese. These alloys are stronger than pure aluminum but still easy to shape. They do not resist heat treatment, so they work best in places where heat treatment is not an option. Also, these alloys are good for anodizing and welding. This feature makes them useful in many industrial and commercial applications.

Among the 3000 series, alloy 3003 is the most used because it has a great mix of qualities. Alloy 3003 has moderate strength and is easy to work with. It also does really well against corrosion, which makes it perfect for many uses. These uses include cooking tools, chemical equipment, storage tanks, and building projects. Its easy shape and ability to resist corrosion make it a favorite choice for makers in the industry.
