It is a common practice to use Class 180 enameled aluminum wire for HDD (hard disk drive) drive coils.

Class 180 enameled aluminum wire has a temperature rating of 180°C, which means that it has high temperature resistance. In HDD drives, the high operating temperatures require the use of wire that can withstand such temperatures.

Class 180 enameled aluminum wire has good thermal stability and is able to maintain its electrical and insulating properties in high temperature environments. This is critical for HDD drives because the coils in the drive generate heat during operation and require a wire material that can withstand high temperatures.


Class 180 enameled aluminum wire uses aluminum as the conductor material, which is lighter compared to copper conductors. This is an important consideration for HDD drives, as lighter wire reduces the overall weight of the drive, improving portability and transportation of the device.

Class 180 enameled aluminum wire has an enameled insulation covering the wire surface, which provides good electrical insulation. This helps prevent current leakage or short circuits between coils, ensuring proper operation and safe performance of the drive.

Class 180 enameled aluminum wire sizes and specifications can be customized to meet specific HDD drive designs and requirements. This includes wire diameter, number of turns and shape of the coil, etc. Depending on the power requirements and space constraints of the drive, the proper size enameled aluminum wire can be selected.

Selecting the proper wire material is critical to the performance and reliability of the HDD drive. In addition to Class 180 enameled aluminum wire, other types of wire materials, such as copper conductors or other temperature grades of enameled aluminum wire, may be considered depending on specific needs. The final selection should be based on a combination of factors such as the device's design requirements, operating environment and reliability requirements.
