常见的磁钴(铝镍钴)系合金含镍14%,钴24%,铝8.5%,铜3%,其余为铁,是仪表工业上重要的永磁合金之一。这样高含量的镍和钴,通常采用重量法或容量法分别测定,手续繁琐,不易掌握。笔者棕合有关方面的资料,试验了镍、钴的系统比色法,简便迅速,准确度和常用的重量或容量法不相上下。
Common magnetic cobalt (AlNiCo) alloy containing 14% of nickel, 24% of cobalt, 8.5% of aluminum, copper 3%, the rest is iron, the instrument is one of the important industrial permanent magnet alloys. Such high levels of nickel and cobalt, usually by gravimetric or volumetric method were measured, complicated procedures, not easy to grasp. I Brown co-related information, the test of nickel, cobalt colorimetric system, simple and quick, accurate and commonly used weight or volume method comparable.
