Prodsuct Description
3003 is an AL-Mn series alloy, which is the most widely used anti-rust aluminum. The strength of this alloy is not high (slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment. Therefore, cold working methods are used to improve its mechanical properties: It has high plasticity in the annealed state, good plasticity during semi-cold work hardening, low plasticity during cold work hardening, good corrosion resistance, good weldability, and poor machinability.
3003 aluminum tube has good formability, weldability, and corrosion resistance. It is used to process parts that require good forming properties, high corrosion resistance, and good weldability or work that requires these properties and higher strength than 1XXX series alloys.
Prodsuct Application
Kitchenware, food and chemical prodsuct processing and storage devices, tanks and tanks for transporting liquid prodsucts, various pressure vessels and tubes made of thin sheets, general utensils, heat sinks, makeup sheets, photocopier drums, and ship materials.

Chemical properties
Corrosion resistance, corrosion resistance of 3003 aluminum tube is very good, close to the corrosion resistance of the industrial pure aluminum, the air fresh seafood such as organic acid gas neutral inorganic salt aqueous solution has good corrosion resistance, corrosion resistance in the dilute acid is also very good in the cold deformation state, 3003 aluminum alloy has a tendency to spalling corrosion, deformation, the greater the peeling off the more serious because of the uneven color after anodic oxidation, so don't usually conduct anodized.
