In order to improve the safety and ignition ability of Ni-Cr thin film igniter, a new Ni-Cr@Al/CuO insensitive energetic element was fabricated by combining Al/CuO energetic thin film with Ni-Cr thin film bridge by magnetron sputtering. The Ni-Cr@Al/CuO insensitive energetic element can be used both as the energy transducer element and as the simplest electrical ignition elements. It simplified the point fire transmission sequence and adapt to the development needs of ammunition miniaturization. The safety of Ni-Cr@Al/CuO was tested at the loading condition of 1A1W5min, and its electric ignition sensitivity and ignition capability were tested. The results show that the 50 ms critical ignition current of the insensitive nucleus Ni-Cr igniter is 3.08 A, 99.9% firing current is 3.18 A, 0.1% firing current is 2.98 A. Under the same conditions, Ni-Cr@Al/CuO insensitive energetic element can ignite B/KNO₃, besides, it can achieve 1mm gap ignition, while Ni-Cr thin film igniter can not successfully ignite B/KNO_3.
