1050 Aluminium Strips Electrical Conductivity
here is a table summarizing the electrical conductivity of 1050 aluminum strips in different tempers. The electrical resistivity is given in ohm-cm, and the International Annealed Copper Standard (IACS) values are calculated for each temper.
Temper |
Electrical Resistivity (ohm-cm) |
IACS Value (approx.) |
1050-O |
0.00000281 |
61.05 |
1050-H14 |
0.00000290 |

0.00000290 |
59.32 |
1050-H18 |
0.00000290 |
59.32 |
Please note that the IACS values are approximate and are calculated using the formula:
IACS=(1Resistivity of the material)×100IACS=(Resistivity of the material1)×100
The resistivity of annealed copper is taken as the reference with a value of 0.00000673 ohm-cm at 20°C, which is assigned an IACS value of 100. The calculated IACS values for the 1050 aluminum tempers are based on their respective resistivities provided in the datasheets.
The IACS values for the 1050 aluminum tempers indicate that they have lower electrical conductivity compared to copper, which is consistent with aluminum’s position in the conductivity series. The slight variations in resistivity and the corresponding IACS values between the different tempers reflect the changes in the material’s microstructure due to the various heat treatments and cold working processes.
1050 Aluminium Strips Thermal Conductivity
The thermal conductivity of 1050 aluminum strips in different tempers, as provided in the datasheets from the links you’ve shared, is summarized in the table below. The thermal conductivity values are given in W/m-K (Watts per meter-Kelvin), which is a measure of a material’s ability to conduct heat.
Temper |
Thermal Conductivity (W/m-K) |
1050-O |
231 |
1050-H14 |
227 |
1050-H16 |
227 |
1050-H18 |
227 |
The thermal conductivity values for 1050-O and 1050-H14 through 1050-H18 are quite similar, with a slight variation between 227 and 231 W/m-K. This indicates that the different tempers of 1050 aluminum have a relatively consistent ability to conduct heat, which is an important property for applications where thermal management is a consideration.
It’s important to note that the thermal conductivity can be influenced by several factors, including temperature, material processing, and the presence of impurities or other alloying elements. The values provided here are typical and may vary depending on the specific manufacturing process and the conditions under which the material is used.

Please note that the inch conversions are based on the approximate conversion factor of 1 inch = 25.4 mm. The flatness tolerance is not provided with specific values because it varies with the dimensions of the material and is typically measured using a bow gauge, which measures the deviation from a flat surface over a specified length. This tolerance must be discussed and specified with the supplier to meet the particular requirements of the application.
