Synthesis and in-situ Mo microalloying of CuCr alloy by aluminothermic self-propagating reduction
Published 2025-03-01“…Therefore, the conductivity of CuCrMo alloy is increased from 12.63 MS m−1 to 17.41 MS m−1. Based on the performance of 12 kV vacuum interrupter assembled with self-propagating CuCr contacts, it is found that compared with CuCr alloy, the insulation, chopping current and breaking performance of the interrupter are obviously improved by adding Mo.…”
