Detailed introduction

About 3003 Aluminium

Aluminum manganese alloy series is a common product. Due to the manganese  alloy element, this product has excellent antirust properties. Its strength is  about 10% higher than that of 1100, and its formability, solubility and  corrosion resistance are good.


It is used to process parts with good formability, high corrosion resistance  and good weldability, or work with these properties and higher strength than  1xxx alloy, such as kitchen utensils, food and chemical products processing and  storage devices, tanks and tanks for transporting liquid products, various  pressure vessels and pipes processed with thin plates, general utensils, heat  sinks, cosmetic plates, etc Photocopier cylinder, ship material.

Corrosion resistance: 3003 has good corrosion resistance, which is close to  the corrosion resistance of industrial pure aluminum. It has good corrosion  resistance to atmosphere, fresh water, sea water, food, organic acid, gasoline,  neutral inorganic saline solution, etc., and also has good corrosion resistance  in dilute acid.

In the cold deformation state, 3003 aluminum alloy has the tendency of  exfoliation corrosion. The larger the deformation is, the more serious the  exfoliation is. Due to the uneven color after anodizing, anodizing treatment is  generally not carried out.


Characteristic for 3003

3003 is al Mn alloy, which is one of the most widely used antirust aluminum.  The strength of this alloy is not high (slightly higher than that of industrial  pure aluminum) and can not be strengthened by heat treatment. Therefore, cold  working method is adopted to improve its mechanical properties: it has high  plasticity in annealing state, good plasticity in semi cold hardening, low  plasticity in cold hardening, good corrosion resistance and good weldability,  Poor machinability. It is mainly used for low load parts that require high  plasticity and good weldability and work in liquid or gas medium, such as oil  tank, gasoline or lubricating oil conduit, various liquid containers and other  low load parts made by deep drawing: wire rod is used for rivets.


Applications for 3003

The product is often used in packaging, mechanical parts, refrigerators, air  conditioning ventilation pipes and other humid environment, the product has good  rust resistance. It is commonly used in ships, ships, vehicles, automobile and  aircraft plate welding parts, pressure vessels requiring strict fire protection,  refrigeration devices, television towers, drilling equipment, transportation  equipment, missile components, armor, etc.


Heat treatment process for 3003

1) Complete annealing: 390-430 ℃; With the different effective thickness of  the material, the holding time is 30-120 min; At the speed of 30-50 ℃ / h, it is  cooled to 300 ℃ with the furnace, and then air cooled.

2) Rapid annealing: 350-370 ℃; With the different effective thickness of the  material, the holding time is 30-120 min; Air or water cooled.

3) Quenching and aging: quenching 500 ~ 510 ℃, air cooling; Artificial aging  95 ~ 105 ℃, 3 h, air cooling; Natural aging 120h at room temperature.
