Introduction to 1100 Aluminum Plates

Aluminum alloys are materials primarily composed of aluminum as the base metal with various other elements added. These alloying elements enhance the properties of aluminum to suit specific applications. Aluminum alloys are categorized into different series, each serving a unique purpose. The 1000 series, in particular, includes aluminum alloys with a purity of at least 99.0% aluminum and minimal alloying elements. Among these, the 1100 aluminum plate is notable for its high purity.

Composition of 1100 Aluminum Plate

The 1100 aluminum plate is classified under the 1000 series of aluminum plates, characterized by its high aluminum content. Its chemical composition is as follows:

  • Aluminum (Al): 99.0%
  • Iron (Fe): 0.95%
  • Silicon (Si): 0.95%
  • Copper (Cu): 0.05%
  • Manganese (Mn): 0.05%
  • Zinc (Zn): 0.10%
  • Other Elements: 0.05% (Each), 0.15% (Total)

The purity of 1100 aluminum makes it an excellent choice for applications where high electrical conductivity is essential, and where resistance to corrosion is not a critical factor.

1100 Aluminum Plate Mechanical Properties

The mechanical properties of 1100 aluminum plate are as follows:

  • Tensile Strength: 90 MPa
  • Yield Strength: 34 MPa
  • Elongation: 30%
  • Hardness (Brinell): 23 HB

These properties make 1100 aluminum a relatively soft and ductile material, well-suited for applications that require forming, bending, and deep drawing. It may not be as strong as some other aluminum alloys, but it serves its purpose in specific use cases.

Physical Properties of 1100 Aluminum Alloy

Physical properties are fundamental characteristics of any material. For 1100 aluminum alloy, the following physical properties are noteworthy:

  • Density: 2.70 g/cm³ (0.0975 lb/in³)
  • Melting Point: 660.3°C (1220.5°F)
  • Electrical Resistivity: 2.67 x 10⁻⁸ ohm-meters

The low density of 1100 aluminum contributes to its lightweight nature, which is a significant advantage in applications where weight is a critical factor.

1050, 1060, 1070, 1100: These alloys have similar physical properties, including low density, a melting point of approximately 660.3°C (1220.5°F), and good electrical resistivity.

1100 Aluminum Sheet Thermal Properties

Aluminum alloys, including 1100, possess excellent thermal properties:

  • Thermal Conductivity: 229 W/m·K (133 BTU·in/ft²·hr·°F)
  • Coefficient of Thermal Expansion (CTE): 23.6 µm/m°C (13.1 µin/in°F)

The high thermal conductivity of 1100 aluminum makes it ideal for applications that require heat dissipation, such as heat sinks and cooling fins. Its CTE is relatively low, indicating good dimensional stability over a wide temperature range.
