Allied Encyclopedia: M81044 Wire

M81044 is a mil spec lead wire that is most commonly used in military applications. This lead wire is specifically used in airframe, avionics, military vehicle, shipboard and missile applications. M81044 wire is used mostly in military applications due to being able to work well in severe conditions such as high temperatures, abrasion and resistance to common chemicals. In addition, these wires also have excellent resistance to cut through, cold flow and shrink back. They also strip and stripe easily. M81044 lead wire is flame retardant and self-extinguishing. Though this lead wire is most often called out as M81044 wire, referencing the MIL-W-81044 specification, this spec is now governed by SAE (Society of Automotive Engineers), and is officially known as AS81044.  

M81044 wire features three options for conductor material; tin-coated copper, silver-coated copper or nickel coated copper. It is insulated with Cross Linked Polyalkene and has a Cross Linked Polyvinylidene Fluoride Jacket which creates for a light or medium weight advantage. See table below for specifications on the 9 of the most common M81044 sub-products. All of these slants are rated to 600V and have a 150°C conductor temperature.

Mil Spec wire and cable is easily identified by the components in its part number. Breaking down the part number by its components will give you detailed information about what is inside the cable and allow you to pick the correct part for your specific application.

Below is an example of the different sections of MIL-W-81044/9

  • MIL-W: These letters are needed to show the part complies with military specification.
  • 81044: Part number
  • /9: This represents the cable’s spec sheet number which can tell you specifics such as conductor, voltage, temperature, etc.

With this information we can now break down MIL-W-81044/9-24-0

  • MIL-W-81044/9: Mil Spec lead part number. The /9 explains that this cable has tin a tin coated copper conductor, XL Polyalkene insulation and a XL PVDF jacket. It is rated to 600V and has a maximum temperature rating of 150°C.  
  • -24: This indicates that the conductor is sized 24 AWG
  • -0: This indicates that the insulation color is black
