Common 1100 Aluminum Sheet Metal Tempers

Aluminum tempers consist of numbers and letters, which indicate the type of treatment the alloy has undergone to achieve the desired mechanical properties. Several of the most common tempers for 1100 aluminum sheet include:

  • O
  • H14
  • H18

O indicates annealed aluminum and is the softest grade of the alloy. H18 is among the hardest tempers with the highest tensile strength. Champagne Metals stocks various thicknesses and sizes of 1100 sheet aluminum to cover your needs.

1100 aluminum sheet offers various benefits, including:

  • Excellent thermal conductivity
  • Outstanding corrosion resistance
  • Exceptional workability
  • High weldability


Because of its low tensile strength and softness, 1100 sheet aluminum is typically unsuitable for most high-pressure or high-strength applications.


1100 sheet aluminum is popular in applications that require soft, light alloys, including:

  • Food and beverage
  • Chemical processing
  • Electrical conductors
  • Heat shields
  • Aerospace components
  • Signage
  • Decorative items


Since it is soft and malleable, 1100 sheet aluminum has outstanding machinability in all tempers.


Aluminum sheet 1100 is highly weldable using many of the most common manual and automated welding methods.

Heat Treatment

1100 aluminum sheet is not treatable with heat.

Aluminum 1100 Sheet Chemical Properties

The chemical composition of 1100 sheet aluminum is 99% to 99.9% pure aluminum. Minor residuals include copper, iron, manganese and silicon.

Mechanical Properties of Aluminum Sheet 1100

Several primary mechanical properties of aluminum sheet 1100 include tensile strength, yield strength and hardness. Typical tensile strength ranges from 75 megapascals (MPa) to 110 MPa, while yield strength varies from 30 MPa to 55 MPa. Hardness is typically 23 HB to 28 HB on the Brinell scale.
