What is 3003 Aluminum Strip?

3003 is an AL-Mn alloy, which is the most widely used rust-proof aluminum. This product has excellent rustproof characteristics and is also known as rustproof aluminum strip. The strength of this alloy is not high (slightly higher than industrial pure aluminum), but the formability, solubility and corrosion resistance are all good. It cannot be strengthened by heat treatment, so cold working methods are used to improve its mechanical properties: high plasticity in the annealed state, good plasticity in the semi-cold hardening, low plasticity in the cold hardening, good corrosion resistance, good weldability, and poor machinability.

Advantages 3003 Aluminum Strip:

The machinability of the 3003 aluminum is considered good for being an aluminum alloy. It is readily machined for different applications. It can either be formed using conventional hot working or cold working. It’s also possible to use conventional welding methods to shape 3003 aluminum. It is sometimes welded to other aluminium alloys, like 6061, 5052, and 6062, which should have an AL 4043 filler rod.

Aluminum 3003 isn’t heat treatable, but it can be forged with heat that’s between 500 and 950 degrees Fahrenheit. When using heat in this range, the aluminum can be hot worked easily. However, it is readily cold worked, which can be done using conventional methods. When annealing the alloy during or after using cold working techniques, it should be performed at 775 degrees Fahrenheit. This will give it enough time to thoroughly heat before being air-cooled. The only way to make this alloy hard is with the use of cold working. It can also be deep drawn, spun, or brazed.

Applications of 3003 Aluminum Strip:

It is mainly used for low load parts requiring high plasticity, good forming property, high anti-corrosion and good weldability, working in liquid or gas medium. Such as the troughs and cans used to transport liquids, pressure cans, storage devices, heat exchangers, chemical equipment, kitchenware, food and chemical handling and storage devices, tanks and cans for transporting liquid products, various pressure vessels and pipes processed in thin sheet, general ware, heat sinks, make-up plates, photocopier rollers, and ship materials.
