随着电子仪器及电气仪表向高精度、微型化方向发展,对于电阻合金除具有一般精密电阻材料性能之外,要求进一步提高其电阻值。我所从七二年开始研制,经过几年努力已研制出性能比较理想的镍锰
With the development of electronic instruments and electric meters toward high precision and miniaturization, the resistance alloys are required to further increase their resistance values in addition to the general precision resistance material properties. I started from 1972, after several years of hard work has developed a relatively good performance nickel-manganese
