3003 aluminum foil

3003 aluminum foil is a widely used anti-rust aluminum foil. Its strength is about 10% higher than that of 1100 aluminum foil. It cannot be strengthened by heat treatment and is a medium-strength aluminum alloy. It is mainly used in industries such as electronic components (electronic foil), honeycomb materials, building material sound insulation (viaducts, high-speed railway highway sound insulation, etc.) and as food packaging foil (3003 aluminum foil packaging bags, vacuum aluminum foil bags).

3003 aluminum foil production process

The specific production process of 3003 aluminum foil is: casting – soaking – hot rolling – pre-annealing – cold rolling – intermediate annealing – cold rolling – foil rolling – slitting – performance testing – packaging.

Henan Huawei has introduced the advanced Zhuoshen foil rolling mill and adopted ANDRITZ profile rollers, which provides guarantee for the realization of high-quality aluminum foil. During the production process, the processing quality, texture, grain structure, composition, etc. of the aluminum foil are strictly controlled, and the product performance reaches the advanced level.

Characteristics of 3003 aluminum foil

Medium intensity

3003 is a medium strength alloy that is 10% stronger than the 1000 series alloys. Although it is not heat treatable, it can be hardened by cold working. There are many temperaments to choose from. Depending on the cold working method used, mechanical properties such as strength can be improved at the expense of plasticity.

Good plasticity and welding properties

The 3003 aluminum foil provided by Henan Huawei has high plasticity, especially in the annealed state. This allows the foil to be easily processed into the desired shape of the final product. When container foils are formed into multi-cavity structures, they need to be resistant to breakage during the stamping process. 3003 aluminum foil has high strength and elongation properties.

Very good corrosion resistance and dielectric properties

The oxide layer formed on the surface of 3003 aluminum foil can resist corrosion by most types of acids and organic substances. More importantly, this oxide layer has a high dielectric constant and its thickness can be controlled. These properties, combined with the ease of formability of 3003 aluminum foil, allow it to be used to manufacture cathodes for electrolytic capacitors of various capacitance values.

Can be used as aluminum honeycomb core material

Our 3003 aluminum foil can also be used as a substrate for aluminum honeycomb panel manufacturing. These honeycomb panels have a high strength-to-weight ratio, allowing them to be used in automotive, aerospace, industrial manufacturing, and construction applications.

Applications of 3003 aluminum foil

From thick foil to single zero foil and double zero foil, this material with a thickness of no more than 0.2mm is widely used in daily life.

There are household foils, container foils, lunch box foils, food foils, flexible packaging foils, beer sealing foils, etc. used in food.

In addition to the kitchen, aluminum foil is commonly used in life, such as medicinal foil, cigarette foil, hairdressing foil and decorative foil.

3003 aluminum foil applications

Other application fields include battery foil, battery soft package foil, electronic label foil, circuit board foil, air-conditioning duct foil, brazing foil, automotive air-conditioning fin foil, heatsink foil, printing foil, electronic foil, thermal insulation foil, circuit board foil, cardboard foil, heat sealing foil, electronic foil, etc.

Casting production process and its introduction

The purpose of melting and casting is to produce alloys with satisfactory composition and high purity of melt, so as to create favorable conditions for casting alloys of various shapes.

Melting and casting process steps: batching --- feeding --- melting --- stirring after melting, slag removal --- pre-analysis sampling --- adding alloy to adjust the composition, stirring --- refining --- static Setting——Guide furnace casting.

Hot rolling production process and its introduction

  • 1. Hot rolling generally refers to rolling above the metal recrystallization temperature;
  • 2. During the hot rolling process, the metal has both hardening and softening processes. Due to the influence of deformation speed, as long as the recovery and recrystallization process is too late, there will be a certain work hardening;
  • 3. The recrystallization of the metal after hot rolling is incomplete, that is, the coexistence of recrystallized structure and deformed structure;
  • 4. Hot rolling can improve the processing performance of metals and alloys, reduce or eliminate casting defects.
    • Hot rolling equipment

      Casting and rolling process

      Casting and rolling process: liquid metal, front box (liquid level control), casting and rolling machine (lubrication system, cooling water), shearing machine, coiling machine.

      • 1. The casting and rolling temperature is generally between 680°C and 700°C. The lower the better, the stable casting and rolling line usually stops once a month or more to re-stand. During the production process, it is necessary to strictly control the liquid level of the front tank to prevent low liquid level;
      • 2. Lubrication uses C powder with incomplete combustion of gas for lubrication, which is also one of the reasons for the dirty surface of casting and rolling materials;
      • 3. The production speed is generally between 1.5m/min-2.5m/min;
      • 4. The surface quality of products produced by casting and rolling is generally relatively low, and generally cannot meet products with special physical and chemical performance requirements.
        • Cold rolling production process

          • 1. Cold rolling refers to the rolling production method below the recrystallization temperature;
          • 2. There will be no dynamic recrystallization during the rolling process, and the temperature will rise to the recovery temperature at most, and the cold rolling will appear in a work hardening state, and the work hardening rate will be large;
          • 3. The cold-rolled sheet and strip have high dimensional accuracy, good surface quality, uniform structure and performance, and products in various states can be obtained with heat treatment;
          • 4. Cold rolling can roll out thin strips, but at the same time, it has the disadvantages of high energy consumption for deformation and many processing passes.
            • Casting rolling

              Introduction to finishing production process

              • 1. Finishing is a processing method to make the cold-rolled sheet meet the customer's requirements, or to facilitate the subsequent processing of the product;
              • 2. The finishing equipment can correct the defects produced in the hot rolling and cold rolling production process, such as cracked edge, oily, poor plate shape, residual stress, etc. It needs to ensure that no other defects are brought into the production process;
              • 3. There are various finishing equipments, mainly including cross-cutting, slitting, stretching and straightening, annealing furnace, slitter, etc.
