铁铬铝丝在刚性药头电雷管电引火桥丝中的探索运用

Fe-Cr-Al Alloy Wires Electric Ignition Component of Rigid Detonators Hot Bridge Wires

文章对铁铬铝丝的性质进行了分析,介绍了铁铬铝合金丝作为刚性电雷管电引火装置的各项性能及生产情况。实验证明:铁铬铝合金丝作为发热桥丝的各种性能均可达到镍铬丝的水平,而且价格便宜,更具实用价值。

The paper analyzed the various properties of Fe-Cr-Al alloy wires, and introduced the performance and production of Fe-Cr-AI alloy wires, which were used as electric ignition component of rigid electric detonators. Experiments to prove： Fe-Cr-A1 alloy wires as heat bridge reach the level of Ni-Cr alloy wires on various properties. Furthermore, the Fe-Cr-AI alloy wires were cheaper and more practical.
