3003 Aluminum Sheet

Designed for sheet metal work, fuel tanks, and other applications that require a slightly higher strength than 1100 series aluminum.

Description

The 3003 aluminum sheet is a pure aluminum that is used commercially. It’s moderately strong and can resist corrosion. Although it’s not heat treatable, it can be easily welded. It can also be formed using hot working and cold working methods. It is one of the alloys that have great machinability. When being forged with heat, it’s best for the temperature to range between 950 degrees and 500 degrees Fahrenheit. It’s best to use a filler rod like the AL 4043 when welding together 3003 aluminum with alloys like 5052, 6062 and 6061.

This aluminum grade can also be easily cold worked and has annealing capabilities, which should be done at 775 degrees Fahrenheit either during or after cold working. Afterward, air cooling should be allowed. The conductivity of 3003 alloys is 40 percent of copper.

The reason this metal is widely used is because it is affordable and strong. Compared to the 1100 series of alloys, 3003 aluminum is 20 percent stronger. This is due to it being integrated with 1.20 percent manganese. It is considered a pure aluminum and is frequently used in various applications, such as for storage tanks, tool boxes, walkways, truck beds, decorative trim and chemical equipment. It can also be used to create fan blades, siding, trailer components, kitchen equipment, cooking utensils and for signage applications.

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.
