The differences and advantages between 1235 aluminum and 1050 aluminum


1235 Aluminum: It is a pure aluminum alloy with a minimum aluminum content of 99.35%. It also contains small amounts of iron and silicon.

1050 Aluminum: Like 1235, it is also a pure aluminum alloy with a minimum aluminum content of 99.50%. It may contain small amounts of other elements, such as iron.

Advantages of 1235 Aluminum:

Softness and Ductility: 1235 aluminum is known for its softness and high ductility, making it suitable for applications where flexibility is essential. It is commonly used in flexible packaging, such as foil for food packaging and insulation.

Corrosion Resistance: Pure aluminum generally exhibits good corrosion resistance, and 1235 is no exception. This makes it suitable for applications where exposure to the elements is a concern.

Advantages of 1050 Aluminum:

High Thermal Conductivity: 1050 aluminum has excellent thermal conductivity, making it suitable for heat exchangers, radiators, and other applications where efficient heat transfer is important.

Anodizing Potential: 1050 aluminum can be easily anodized, providing a protective coating that enhances its corrosion resistance and allows for various color options. This makes it suitable for decorative applications.


1235 Aluminum: Commonly used in the manufacturing of foil for flexible packaging, household foil, and insulation materials.

1050 Aluminum: Used in applications such as heat exchangers, radiators, cookware, and certain types of industrial equipment. Its anodizing capabilities also make it suitable for decorative purposes.


1235 Aluminum: The cost of 1235 aluminum may vary, but it is generally used in applications where its specific properties are required, such as flexible packaging.

1050 Aluminum: Being a common and widely used pure aluminum alloy, 1050 aluminum is often more readily available and may have a lower cost compared to some specialized alloys.

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.
