1000 Series Aluminum Plate Overview

The 1000 series aluminum alloys represent the purest commercially available aluminum grades. Each alloy in this series contains at least 99% aluminum, giving it exceptional resistance to corrosion from chemicals and atmospheric exposure.

Because of this high purity, 1000 series aluminum plates offer:

  • Excellent corrosion resistance
  • High electrical and thermal conductivity
  • Outstanding workability
  • Relatively low mechanical strength

These characteristics make the series ideal for applications where formability and corrosion resistance are critical.

1050 Aluminum Plate Introduction and Applications

1050 aluminum plate is the most widely used grade within the 1000 series. It contains a minimum of 99.5% pure aluminum and has the lowest strength among commercial aluminum alloys but exceptional ductility.

 

The most common temper is 1050 H14 aluminum plate, which is half-hard and extremely easy to bend and form. Due to its high reflectivity, 1050 aluminum sheet is frequently used in the lighting industry for reflectors.

 

At GNEE, 1050 aluminum plate is supplied with a peel-off PVC protective film on one side, helping prevent surface damage during cutting, fabrication, and transportation.

 

1050 Aluminum Plate Equivalent Designations

1050 aluminum plate is also known by the following international designations:

AA1050

A91050

S1B

It is important to note that 1050 aluminum is exclusively a sheet and plate specification. Bars, rods, and extrusions are not produced in this grade.

 

Corrosion Resistance of 1050 Aluminum Plate

Thanks to its 99.5% minimum aluminum content, 1050 aluminum plate offers excellent corrosion resistance. It performs well in outdoor environments and resists chemical attack without rusting.

While it can be used in saltwater environments, aluminum grades such as 5251 may provide better long-term marine performance.

 

Welding and Fabrication of 1050 Aluminum Plate

Welding Performance

1050 aluminum plate is excellent for welding, brazing, and soldering, making it suitable for a wide range of fabricated components.

Machining Characteristics

Due to its softness, 1050 aluminum plate is not ideal for conventional machining, as tools may clog easily. However, it is well suited for laser cutting and sheet metal processing.

Cold Working and Forming

1050 H14 aluminum plate is designed for cold working and forming. It can be bent sharply, folded back on itself, and reshaped without cracking, making it one of the most ductile aluminum plates available.

 

Surface Treatment Options for 1050 Aluminum Plate

1050 aluminum plate supports multiple finishing processes, including:

Protective anodizing

Color anodizing

Bright anodizing

Hard anodizing

Polishing

Powder coating

This makes it suitable for both functional and decorative applications.
