The 3003 aluminum coil 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.
