A3003 aluminum Alloy's Characters &Application
- May 22, 2017 -

As an AL-Mn alloy , A3003 aluminum alloy is widely used as a rust-proof aluminum material . Its strength alloy is not high (slightly higher than the industrial pure aluminum) and it can not bear heat treatment,so cold processing methods is used  to improve its mechanical properties

In the annealing state A3000 series aluminum has a high plasticity; in the semi-cold hardening its plasticity  is still good,;in cold hardening the plasticity is low.It is of good corrosion resistance, good weldability but poor cutting performance.

A3003 aluminum  coil/foil are mainly used for low load parts that require high plasticity and good weldability and work in liquid or gaseous media, such as mailboxes, petrol or lubricants conduits, liquid containers and other small load parts made with deep drawing.a3003 aluminum wire/rod  is suitable for making  rivets.


A3003 series aluminum product is of good corrosion resistance and often used for external the packaging, mechanical parts, refrigerators, air conditioning and ventilation pipes and other humid environment.

While A3003 aluminum plate is commonly used for boats, ships,vehicles bodies, automotive and aircraft plate welding parts, fireproofing pressure vessels, refrigeration equipment ,television towers, drilling equipment, transportation equipment, missile components, armor and so on.
