Overview of the characteristics of 3003 aluminium strip

3003 aluminium strip is made of 3003 aluminium alloy. The 3 series aluminum alloy is also called an aluminum-manganese alloy. But not heat treatment, only cold working.

The strength of 3003 aluminum is about 10% higher than that of 1100 aluminium, and it has good formability, weldability, and corrosion resistance.

The raw materials of the aluminium strip are pure aluminum or aluminium alloy cast-rolled aluminum coils and hot-rolled aluminium coils, which are rolled into thin aluminum coils of different thicknesses and widths by a cold rolling mill, and then longitudinally cut into aluminum coils of different widths by a slitting machine according to the application. bring.

Commonly used aluminium strip series are 1000, 3000, 5000 and 8000

The most commonly used ones should belong to the all-soft series because the O state is easier to stretch and bend.

Application of 3003 aluminium strip

Such as kitchenware, 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, photocopier rollers, and ship materials.

Mainly used for low-load parts that require high plasticity and good weldability, working in liquid or gas medium, such as mailboxes, gasoline or lubricating oil conduits, various liquid containers and other small-load parts made by deep drawing: wire rod Used to make rivets.

3003 aluminium strip for insulating glass

3003 aluminum strip can be used as an insulating glass profile, which is a series of metal materials, which finally stand out after comparing with each other. Its quality is directly related to the use effect, durability, and thermal insulation function of insulating glass.

The main function is to make two or more pieces of glass in the insulating glass evenly separated and effectively supported.

3003 aluminium alloy strip for power battery shell

Material requirements:

  • The surface roughness of the strip is controlled at 0.20-0.35μm, and the surface is required to be smooth and clean, without periodic sticking, marks, and other defects.
  • Obvious bright and dark bands are not allowed.
  • Corrosion, penetrating pores, scratches, metal, and non-metallic indentations are not allowed.

Power battery housing

Power battery housing

At present, aluminum power battery shells for electric vehicles generally use 3003-O or 3003-H14 aluminium alloys. This material is easy to form, has high-temperature corrosion resistance, good heat transfer, and electrical conductivity.

The aluminum power battery shell (except the shell cover) of 3003 aluminum alloy can be drawn and formed at one time. Compared with the stainless steel shell, the welding process of the bottom of the box can be omitted.

HUAWEI aluminum tape packaging, transportation, and storage


1. The aluminium strip should be rolled tightly, no loose layer is allowed; no joints are allowed in the coil; the edge of the aluminum strip should be cut neatly, without cracks and burrs, the stacking fault should not be greater than 3mm, the tower shape should not be greater than 20mm, and the coil core must be smaller than The width of the aluminum strip shall not have aluminum plates protruding at both ends;

2. The aluminum coils should be stacked in a flat cylindrical shape, the outer opening of each aluminum coil should be on the same vertical line, and the weight of each box should not exceed 5 tons. Single-layer packing box for flat transportation;

3. Each box of aluminum should have a packing list, including the serial number, tensile strength, elongation, net weight and gross weight of each roll of aluminum;

4. Each roll of aluminum should have a certificate of conformity, and indicate the inspection index, weight, etc.



When transporting aluminum materials, do not throw, violently impact, spray oil and be contaminated by chemicals.



1. Do not be hit or thrown during transportation;

2. Aluminum materials should be stored in a well-ventilated place, away from heat sources, oil stains and chemicals, and should not be damp, and should not be stored outdoors;

3. Aluminum strips should be used as soon as possible;

4. Please do not open aluminum materials that are not in use temporarily. For aluminum that has been opened but not used, it should be sealed as soon as possible, and a desiccant should be placed in the package.
