Super Core is manufactured using an innovative process that is completely different from that for conventional silicon steel sheets. These are the highest grade, non-oriented magnetic steel sheets available. Conventional silicon steel sheets have a Si (silicon) content of 3.5% or less. It has long been known that the magnetic characteristics of a silicon steel sheet improve as the Si content increases, peaking at 6.5%. However, it has been impractical to produce thin steel sheets with a Si content of over 3
JNEX-Core is the highest-grade non-oriented magnetic steel sheets manufactured with a production method (CVD process) that is completely different from that for conventional silicon steel sheets, allowing a previously impossible Si content of 6.5% 与以往的硅钢片相比，JNEX铁芯采用了完全不同的制造方法（CVD法）从而实现了以往不可能的6.5%Si含量。 最高端的无取向硅钢片。
