1100 aluminum sheet vs 1200 aluminum sheet

Both 1100 aluminum sheet and 1200 aluminum sheet are pure aluminum sheet materials, and the difference between them mainly lies in the purity and chemical composition of aluminum.

The aluminum content of 1100 aluminum plate reaches 99%. It is a non-heat-treated alloy aluminum plate with good machinability, corrosion resistance and electrical conductivity. It is widely used in construction, aviation, electronics and other fields.

The aluminum content of 1200 aluminum plate is as high as 99.5%, which is a high-purity aluminum plate, which also has good machinability, corrosion resistance and electrical conductivity, but it is more suitable for applications requiring higher purity than 1100 aluminum plate, such as Electronics, chemical industry, medical and other fields.

For buyers, whether to choose 1100 aluminum plate or 1200 aluminum plate depends on the specific application field and demand.

1200 aluminum plate product introduction

Alloy 1200 is a commercially pure aluminum alloy with excellent corrosion resistance, high thermal and electrical conductivity, good formability, and low strength. It is primarily used in applications where its specific properties are advantageous, such as electrical conductors, heat transfer devices, reflectors, chemical handling equipment, food processing containers, and more.

However, for applications requiring higher strength, it is more common to use aluminum alloys from the 2xxx, 5xxx, 6xxx, or 7xxx series. These alloys offer enhanced mechanical properties and are available in various plate thicknesses.

If you are specifically looking for aluminum plates with higher strength, it would be advisable to consider aluminum alloys such as 2024, 5052, 6061, or 7075。

The alloy composition of 1200 aluminum sheet

Alloy 1200 is an aluminum alloy that belongs to the 1xxx series, which are known as commercially pure aluminum alloys. Alloy 1200 has a minimum aluminum content of 99.00% and is generally considered to be 99.00% pure aluminum.

The composition of alloy 1200 typically includes the following elements:

  • Aluminum (Al): The primary component, comprising a minimum of 99.00% of the alloy.
  • Iron (Fe): The maximum allowable content of iron in alloy 1200 is 0.050%.
  • Silicon (Si): The maximum allowable content of silicon in alloy 1200 is 0.050%.
  • Copper (Cu): The maximum allowable content of copper in alloy 1200 is 0.050%.
  • Manganese (Mn): The maximum allowable content of manganese in alloy 1200 is 0.050%.
  • Zinc (Zn): The maximum allowable content of zinc in alloy 1200 is 0.050%.
  • Other trace elements: Alloy 1200 may contain trace amounts of other impurities or elements, but they are typically present in very small quantities.

Specifications of 1200 aluminum plate

In general, the specifications of aluminum plates, including alloy 1200, can vary depending on the specific requirements and standards set by manufacturers or customers. Some common specifications for aluminum plates, including those made from alloy 1200, may include:

Thickness: Aluminum plates can be available in various thicknesses, typically ranging from a few millimeters to several inches or more.

Width and Length: The dimensions of aluminum plates can vary, and they are usually provided in terms of width and length. Standard widths and lengths are commonly used, but custom sizes can also be manufactured based on specific requirements.

Temper: Aluminum plates may come in different tempers, which indicate the level of hardness and strength achieved through various heat treatment processes. For alloy 1200, the most common temper is typically “O” (annealed), as it is a non-heat-treatable alloy.

Surface Finish: Aluminum plates can have different surface finishes, such as mill finish (smooth and untreated), brushed finish, or coated finish, depending on the application and desired aesthetics.

Product features of 1200 aluminum sheet

Corrosion Resistance: Aluminum in the 1xxx series, including 1200, exhibits excellent corrosion resistance, especially in non-industrial environments. It resists atmospheric corrosion and is suitable for applications where exposure to moisture or corrosive elements is a concern.

Electrical Conductivity: Aluminum in the 1xxx series is known for its high electrical conductivity. It is often used in electrical applications where excellent conductivity is required, such as conductors, busbars, and electrical transmission lines.

Thermal Conductivity: 1200 aluminum, like other aluminum alloys, has good thermal conductivity. It can efficiently conduct heat and is utilized in heat transfer applications like heat exchangers, radiators, and other heat dissipation devices.

Formability: Aluminum in the 1xxx series, including 1200, offers good formability and can be easily worked with using common fabrication processes such as bending, stamping, and deep drawing. This characteristic makes it suitable for applications that require complex shapes or intricate designs.

Lightweight: Aluminum, in general, is a lightweight material, and the 1xxx series is no exception. It has a low density, which makes it advantageous for applications where weight reduction is crucial, such as aerospace, automotive, and transportation industries.

Reflectivity: Aluminum in the 1xxx series typically exhibits high reflectivity. This property makes it suitable for applications in the lighting industry, such as reflectors, light fixtures, and decorative surfaces where high reflectance is desired.

Non-Heat Treatable: Aluminum in the 1xxx series, including 1200, is considered non-heat treatable. It cannot be hardened through heat treatment processes but can be annealed for stress relief.
