MIL-DTL-32630-vs-ASTM-B33-and-AS29606
Metal conductors have been the primary (and pretty much only) means of transferring electrical energy for centuries. With recent technological developments, it is possible to use alternative materials such as nanotubes and metalized fibers as conductors. Because these non-traditional conductors rely on alternative materials, thorough testing is needed to assess their viability for high demand applications like aerospace systems. For conventional aerospace conductor procurement, the progression is clear: ASTM B33 qualifies an upstream tin-coated copper wire material, AS29606 qualifies a released aerospace stranded conductor, and MIL-DTL-32630 qualifies unconventional conductor technology, whose material architecture creates additional electrical, environmental, combustion, and termination risks. This article reviews the requirements of these non-traditional conductors and how they align with traditional conductors. Read more
