Introduction to 3003 aluminum coil

 

3003 aluminum coil is a commonly used product in the aluminum-manganese alloy series. Thanks to the manganese alloy element, this product has excellent rust-proof properties and is also known as rust-proof aluminum.

The strength is about 10% higher than 1100, and the formability, the solubility, and the corrosion resistance are both good. Used to process parts that require good formability, high corrosion resistance, or require both these properties and work with higher strength than 1XXX alloys, such as kitchenware, food, and chemical processing.

Application of 3003 aluminum coil

 

The most common applications for the 3003 aluminum coil are for fuel tanks, sheet metal work and other types of projects that need a metal that is stronger than the 1100 series aluminum. In some cases, it is used for cooking utensils, refrigerator panels, gas lines, storage tanks, garage doors, builder’s hardware and awning slats.

Chemical properties of 3003 aluminum coil

 

Corrosion resistance: 3003 aluminum coil has good corrosion resistance, close to the corrosion resistance of industrial pure aluminum, and has good corrosion resistance to atmospheric, fresh water, sea water, food, organic acid, gasoline, neutral inorganic salt aqueous solution, etc. The corrosion resistance in dilute acid is also good.

In the cold deformation state, the 3003 aluminum alloy has a tendency to peel off and corrode, and the larger the deformation, the more severe the peeling. Since the color is not uniform after anodization, the anodization is generally not performed.
