Core elements of 3000 series aluminum alloy

3000 series aluminum alloy is an aluminum-manganese alloy whose main components are aluminum, manganese and a small amount of other alloying elements. They have higher strength than pure aluminum while maintaining good formability and corrosion resistance. These alloys are not heat treatable and are suitable for anodizing and welding. 3003 alloy is the most widely used of all aluminum alloys.

3000 series aluminum alloy features

Good corrosion resistance: Due to the manganese content in the alloy, 3000 series aluminum alloys have good corrosion resistance, making them suitable for applications that work in humid or corrosive environments.

Good forming and processing properties: These alloys are easy to process and form, and are suitable for various processing techniques, such as deep drawing, cold drawing, bending, etc. This makes them widely used in the manufacture of containers, pipes and various shaped products.

Moderate strength: 3000 series aluminum alloy has moderate strength, making it suitable for some applications with medium strength requirements, such as aircraft, ships, auto parts, etc.

Excellent welding properties: These alloys generally have good welding properties and can be processed by common welding methods (such as TIG welding, resistance welding).

Wide application: Due to its balance of properties, 3000 series aluminum alloys are widely used in manufacturing aircraft parts, automobile parts, tanks, radiators, pipes and other products.

Feasibility of anodizing: 3xxx series aluminum alloys, also known as “aluminum-manganese alloys”, will not reduce the corrosion resistance of the anodized film, but due to Al-Mn intermetallic compound particles, the anodized film will appear gray or gray-brown.

A brief introduction to 3003 aluminum alloy

It is an AL-Mn alloy and 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.

1.5Mm 3000 Series Aluminum Sheet

1.5Mm 3000 Series Aluminum Sheet

It has high plasticity in the annealed state, good plasticity in semi-cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability, and poor machinability.

It is mainly used for low-load parts that require high plasticity and good weldability and work in liquid or gas media, such as fuel tanks, gasoline or lubricating oil conduits, various liquid containers and other small-load parts made by deep drawing.

Typical applications of 3004 aluminum alloy

3004 aluminum alloy: has good corrosion resistance and processability, and is often used to manufacture beverage cans, cosmetic packaging, auto parts, building materials, etc.
