磁触发器是可控硅触发线路中控制可控硅导通角大小,起功率放大作用的磁性器件,而磁触发器铁芯的质量又是影响其控制特性的关键。高性能的磁触发器要求磁芯材料的饱和磁滞回线具有高的矩形比(B_r/B_s)、高的饱和磁感应强度(Bs)和狭窄的面积(最小的矫顽力H_c)。在金属软磁材料中,1J85合金是我国研制的一种高Ni复杂坡莫合金,类似国外超坡莫合金。它含有80%的Ni、5%的Mo、 The magnetic trigger is a magnetic device that controls the conduction angle of the thyristor in the thyristor trigger circuit and plays the role of power amplification. The quality of the magnetic trigger core is also the key factor that affects the control characteristics. High-performance magnetic flip-flops require that the saturation hysteresis loop of the core material has a high squareness ratio (B_r / B_s), a high saturation magnetic flux density (Bs), and a narrow area (minimum coercivity H_c). In the metal soft magnetic material, 1J85 alloy developed in our country is a high-Ni complex permalloy, similar to foreign super permalloy. It contains 80% Ni, 5% Mo,
