Introduction to Taiyuan Yaoqiang Pure Iron Co., Ltd. (Electromagnetic Pure Iron / Electrical Pure Iron / Industrial Pure Iron):

(1) Yaoqiang Pure Iron Grades: (DT3, DT4, DT4A, DT4E, DT4C, DT8, DT9)

(2) Yaoqiang Pure Iron Forms: Pure Iron Medium Plate, Pure Iron Round Steel, Pure Iron Coil Rod, Pure Iron Cold-Rolled Sheet, Pure Iron Coil, Pure Iron Sheet Slitting, Yaoqiang Pure Iron, Pure Iron Tube, Pure Iron Slab, Pure Iron Forged Material.

(3) Yaoqiang Pure Iron Applications: Used in electrical appliances, telecommunications, instruments, and various magnetic components, electromagnetic elements such as relay pure iron, solenoid valve pure iron, electromagnetic lock pure iron, alloy electromagnetic pure iron, medium and heavy plate pure iron for galvanizing pots, Yaoqiang pure iron, magnetic separator pure iron, pure iron for iron removers, pure iron for sensors, pure iron for electromagnetic clutches, pure iron for elevator brakes, pure iron for claw poles, core materials for various types of relay cores, armature yokes, and strong electromagnets; Yaoqiang pure iron; magnetic components for instruments and meters; DC motor cores and housings; electrical or magnetic parts for automobiles, tractors, and lathes; brakes, clutches. Magnetic shielding equipment such as various magnetic shielding covers or shielding boxes, requiring high shielding performance. Sealing materials, etc.

(4) Yaoqiang Pure Iron Performance:

1) Excellent electromagnetic properties. Low coercivity (Hc), high permeability μ, high saturation magnetic induction (Bs), stable magnetism, and no magnetic aging.

2) High steel purity. The Yaoqiang electromagnetic pure iron series are all killed steels, and through refining, the internal structure is dense, uniform, and good, with low gas content. The finished product carbon content is ≤0.004%, providing reliable conditions for simplifying and shortening part annealing processes.

3) Good cold and hot working performance. Cold working such as turning, upsetting, punching, bending, drawing, etc., presents no issues. Hot working, such as re-forging and re-rolling, has low red brittleness sensitivity; many grades have no red brittleness zone, allowing processing within a wide temperature range.

4) Good surface quality. Has good welding and electroplating performance.

5) High dimensional accuracy. Can provide precision cold-rolled sheets; for example, for sheet thickness ≤1.5mm, thickness tolerance can be guaranteed ≤0.03mm; for sheet thickness >1.5mm, thickness tolerance can be guaranteed ≤±0.05mm.
