3003 aluminum alloy is mainly composed of aluminum, manganese and other impurities. Aluminum is the main component, accounting for more than 98%, and the content of manganese is about 1%. Other impurities elements such as copper, iron, silicon and so on are relatively low in content. Because it contains manganese element, the 3003 alloy has good oxidation resistance and corrosion resistance, and can maintain the surface finish and gloss for a long time in a humid environment, so it has been widely used in the Marine environment, such as shipbuilding, Marine platform construction and other fields.Secondly, 3003 aluminum alloy has a high strength, although 3003 alloy contains a high manganese element, but its strength is still higher than pure aluminum, so in the need of high strength, such as aerospace field, 3003 alloy has also been widely used, such as aircraft shell, engine parts, etc.In addition, because 3003 alloy contains silicon elements, it has better processing, can be deep flushing, stretching, welding and other processing, so it has been widely used in automobile manufacturing, construction engineering and other fields, such as automobile body plate, building exterior wall decorative board, etc.

Performance of the 3003 aluminum alloy

1.Good formability and weldabilit

3003 aluminum alloy has good formability and weldability. This is due to the good plastic and machable properties of aluminum, so it can be formed into different shapes and sizes by various processing methods.

3003 aluminum alloy can be in different states during processing, the common processing states include the following:

1.Quenching state: the quenching state of 3003 aluminum alloy, after quenching treatment, usually has a high hardness and strength, which is suitable for applications with high material strength requirements.

2.Softening state: through solid solution treatment and natural aging or artificial aging treatment, 3003 aluminum alloy can be changed from quenching state to softening state, so that it has better plasticity and processing performance.

3.Semi-hard state: semi-hard state is a state between quenching state and softening state, 3003 aluminum alloy in this state has moderate hardness and plasticity, suitable for some high material strength and shape requirements.

4.Annealing state: by heating to a certain temperature after slow cooling, 3003 aluminum alloy can be in the annealing state, at this time the material has good plasticity and toughness, suitable for some processing processes with high requirements on the material shape.

5.Cold processing hardening state: after cold processing of 3003 aluminum alloy will harden, at this time the strength of the material increases, but the plasticity is reduced, suitable for the manufacture of parts requiring higher strength.
