|5083||Higher strength or improved corrosion resistance required, particularly for ship hull applications.|
To soften Alloy 3003 it can be annealed by heating to 415°C, hold until uniform temperature then cool; the rate of cooling is not important.
3003 aluminum has a lot of great characteristics that make it a popular choice. Other than being weldable and corrosion-resistant, it also has a surface that has a highly polished finish, making it an attractive choice. Although thin, it cannot be bent easily, instead requiring special tools to do so.
Aluminim 3003 alloy metal is easily welded and brazed, but soldering is limited to the torch method.
The conductivity of 3003 alloys is 40 percent of copper.
The main alloying ingredient is Manganese, which gives it greater strength than 1100 while retaining most of the desirable qualities of the 1XXX Series. Due to its excellent formability, 3003 has a wide range of uses including cookware.

What is the difference between 5052 & 3003 aluminum?
3003 aluminum sheet and 5052 aluminum sheet are typically known as “Common Alloys” because they are two of the most widely specified alloys in the aluminum industry.
3003 is fairly soft and has good corrosion resistance, good drawing, good workability, moderate strength, and is weldable, while 5052-h32 is stronger and has better corrosion resistance, good drawing, good formability, higher strength, and also is weldable.
3003 is primarily alloyed with Manganese (Mn) and the primary alloy ingredient for 5052 is Magnesium (Mg). In all, you’ll see that 3003 is an alloy of Silicon, Iron, Copper, Magnesium, and Zinc, while 5052 is an alloy of Silicon, Copper, Manganese, Magnesium, Chromium, and Zinc. See the table below for the percentage of alloying elements in each common alloy.
