How is Aluminum 1100 Processed

Aluminum 1100 is often used in various applications such as chemical equipment, reflectors, heat exchangers, and kitchenware. The processing of aluminum 1100 typically involves several steps:


The initial step in processing aluminum 1100 involves melting the raw aluminum and casting it into various shapes, such as billets, ingots, or sheets. These shapes can then be further processed into desired products.


Aluminum 1100 can be rolled into thin sheets or coils through a process called rolling. This involves passing the metal through a series of rollers, gradually reducing its thickness to the desired dimensions. This process is commonly used to create aluminum foil, sheet metal, and other flat products.


Extrusion is a method used to create complex shapes by forcing aluminum through a die under high pressure. While aluminum 1100 may not be as commonly extruded as other alloys, it is possible to extrude it to form profiles with unique cross-sectional shapes. This process is useful in creating structural components and frames.


Annealing is a heat treatment process used to improve the mechanical properties and formability of aluminum 1100. It involves heating the material to a specific temperature and then slowly cooling it. This process can help relieve internal stresses, increase ductility, and improve the material’s workability.


Aluminum 1100 is relatively soft compared to other aluminum alloys, making it easy to machine. It can be cut, drilled, milled, and turned on standard machine tools. The alloy’s excellent machinability makes it suitable for various precision components.


Aluminum 1100 is weldable using various welding techniques, including TIG (Tungsten Inert Gas) welding, MIG (Metal Inert Gas) welding, and resistance welding. Welding may be necessary to join aluminum 1100 components or to make repairs.

Forming and Bending

Due to its excellent formability, aluminum 1100 can be easily bent and formed into various shapes without the risk of cracking. This property makes it suitable for applications where shaping or bending is required.


Aluminum 1100 can be finished through processes like anodizing, painting, or powder coating to improve its appearance, corrosion resistance, and durability.

Good Formability: Aluminum 1100 is highly malleable and can be easily formed and fabricated using various processes, including bending, deep drawing, and rolling. It is often used in the manufacture of sheet metal products, such as cookware and signage.

Soft and Ductile: It is a soft and ductile material, which means it can be easily worked and shaped without the need for extensive heat treatment. This characteristic makes it suitable for cold working processes. Aluminum 1100 is among the softest aluminum alloys and therefore is not used for high-strength or high-pressure applications. Though it is usually cold worked, pure aluminum can be hot worked as well, and in such cases it is forged anywhere from 700°F to 950°F. More frequently, though, aluminum is shaped by spinning, stamping and drawing processes, none of which require the use of high heat. These processes produce aluminum shapes in the form of foil, plates, round bars, sheets, strips, wire and many other shapes.

Low Strength: One of the limitations of aluminum 1100 is its relatively low strength compared to other aluminum alloys. It is not typically used in structural applications where high strength is required.

Weldability: Aluminum 1100 is weldable using various methods, such as TIG (Tungsten Inert Gas) welding and MIG (Metal Inert Gas) welding, making it versatile for joining applications.

Non-Heat Treatable: Aluminum 1100 is a non-heat treatable alloy, which means it does not gain significant strength through heat treatment. Its mechanical properties are largely determined by cold working processes.

Excellent Reflectivity: This alloy exhibits high reflectivity for both visible and infrared light, making it suitable for applications where reflective surfaces are needed, such as in lighting fixtures and solar reflectors.

Low Density: Aluminum 1100 has a low density, making it lightweight compared to many other materials. This characteristic is advantageous in applications where weight reduction is a primary concern.

Food-Grade:Because of its corrosion resistance and non-toxic properties, aluminum 1100 is often used in the food industry for packaging, containers, and utensils.

Common problems in the application of aluminum discs

Aluminum discs are widely used in the production of kitchenware, and the following problems are often encountered in the spinning or drawing process. Huawei Aluminum tries our best to avoid these problems during the production and transportation process.

Spinning cracking

In the spinning process, due to the presence of sand, impurities, or embedded metal, the aluminum wheel may have crack, edge crack and some other problems. This wastes a lot of time and cost. Such problems often occur in aluminum discs produced from scrap.

Orange peel problem

During spinning, sometimes the surface of the finished pot is not smooth and needs to be polished. The main reason for these problems is that the grain size of aluminum circle is secondary or the head and tail of materials are not completely removed in the production process of aluminum circle & disc.

Surface oxidation

Although aluminum disc has good rust resistance, if aluminum disc is corroded by rainwater or water during storage or transportation process, its surface is easy to be oxidized. It will affect the beauty of kitchenware. Therefore, the package must be tight and with enough desiccant.

Insufficient weight

The packaging of aluminum circle is wooden pallet. Generally, the weight of each pallet is about 1000kg to 1500kg. According to international standards, the weight tolerance is+/- 3 ‰. However, due to the difference in scale and packaging weight, many factories will be short of 5KGS to 10KGS per pallet.

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.
