3003 aluminum alloy belongs to the 3000 series It is a kind of Mn-Al alloy. Besides Mn, other metal elements include silicon, iron, copper and zinc.

Like other 3000 series aluminum alloys, 3003 aluminum alloys are not heat treatable. It can only be hardened by cold work. Due to the addition of manganese, its strength is higher than that of the 1000 series aluminum alloy. But compared with other heat treatable aluminum alloys, 3003 aluminum has no advantages. it belongs to a medium strength alloy.

Although the strength of 3003 aluminum alloy is not very high, it also has many advantages. The main purpose of this article is to introduce the 3003 aluminum alloy.

  1. Weldability: 3003 aluminum alloy has good weldability and can be welded and brazed by all methods.
  2. Corrosion resistance: The corrosion resistance of 3003 aluminum alloy is very good. Close to the corrosion resistance of industrial pure aluminum. It is good for atmosphere, fresh water, sea water, food, organic acid, gasoline, dilute acid solution and neutral inorganic salt solution corrosion resistance.
  3. Plasticity: It has high plasticity in the annealed state, good plasticity in semi-cold work hardening. Low plasticity in cold work hardening.
  4. Machinability: 3003 aluminum alloy is easy to machine and can be machined very well.

3003 aluminum use

  1. Can Aluminum 3003 be bent?

The addition of Mn to the 3003 aluminum alloy does not reduce its ductility. The 3003 aluminum alloy has medium strength, the best cold workability, and an equal high elongation of 25%. It also determines that the 3003 aluminum alloy is the best Applied to bent aluminum alloys.
Although 3003 aluminum alloy is easily bendable, its acceptable minimum bend radius is affected by many factors. Such as tempering, mandrel function, alloy and cross-sectional measurements. So it is also difficult for us to give general rules about bending radii.

2. Can Aluminum 3003alloy be welded?

The weldability of 3003 aluminum is very good. It can be welded by common methods, including gas welding, electric welding and resistance welding. At the same time it can also be welded and brazed by other methods.
Because 3003 aluminum plate has good weldability, it is used in the welding of ships, vehicles and aircraft.

3. Can 3003 aluminum be anodized?

One of its advantages is that aluminum can be anodized. Anodizing can improve the anti-corrosion properties of aluminum, thereby improving the long-term durability of aluminum materials. But, 3003 aluminum alloy is usually avoided for anodizing treatment.

In the process of anodizing, 3003 aluminum alloy is very easy to leave brown color. The color is uneven after anodization, so 3003 aluminum alloy is generally not anodized.

4. Is 3003 aluminum magnetic?

3003 aluminum alloy is not magnetic.
