High purity iron is refined by vacuum melting. 2N=99.0% Fe, 3N=99.9% Fe, 4N=99.99% Fe, with ultra-low impurity content.
Delivery form: ingot, block, bar, plate, pellet, powder. Delivery state: annealed, hot rolled, ground, polished.

DT series is typical soft magnetic pure iron. DT4A, DT4E, DT4C represent upgraded magnetic grades in sequence, with lower coercivity and better magnetic permeability.

YT raw pure iron is low-carbon iron material for metallurgical additive, complying with GB/T 9971-2017.
YT1, YT2, YT3 have gradually lower impurity content.
