Aluminum 1100

Aluminum 1100, also known as UNS A91100 or simply 1100, is a commercially pure aluminum alloy characterized by its excellent corrosion resistance, high thermal and electrical conductivity, and ease of workability. It is part of the 1xxx series of aluminum alloys, which are primarily composed of aluminum with small amounts of other elements. Aluminum 1100 contains a minimum of 99% aluminum by weight, making it one of the purest aluminum alloys available. This high purity gives it several desirable properties and makes it suitable for various industry applications.

How Aluminum 1100 is 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.

Quality Control

Throughout the processing steps, quality control measures are taken to ensure that the aluminum meets the required specifications and standards for the intended application. This includes checking for thickness, flatness, and mechanical properties.

  1. Excellent Corrosion Resistance: Aluminum 1100 offers excellent resistance to corrosion, making it suitable for use in a wide range of environments, including marine and chemical applications.
  2. High Thermal and Electrical Conductivity: This alloy has high thermal and electrical conductivity, making it ideal for applications that require efficient heat transfer or electrical conductivity, such as in heat exchangers and electrical conductors.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
