3003 is a typical alloy of Al-Mn series anti-rust aluminum. Its outstanding feature is good corrosion resistance, which is similar to pure aluminum. Its strength is higher than that of pure aluminum, and it has high plasticity and good deep-drawing formability. It is suitable for chemical equipment, civil hardware and other places that need to be processed and formed, and must have good corrosion resistance and medium strength.

The main alloying element of 3003 alloy is Mn. Mn and Al form MnAl6 dispersed particles, which hinder the growth of grains during alloy annealing to obtain fine grains, and fine grains are an important indicator for optimizing material properties. On the other hand, The electrode potential of MnAl6 is actually equal to that of pure aluminum (both are 0.86 volts). MnAl6 can dissolve the Fe element in the alloy to form (FeMn)Al6, which reduces the FeAl3 in the alloy, thereby minimizing the potential difference between the alloy and Al. , to increase the corrosion resistance of the alloy.

3003 series aluminum plate is a common product of aluminum-manganese alloy series. Due to the manganese alloy element, this product has excellent anti-rust properties, also known as anti-rust aluminum plate.
