Pure iron material DT4E/DT4C for solenoid valve cores, offering excellent magnetic permeability and strong suction force.

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, 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 clutchers, pure iron for elevator brakes, pure iron for claw poles, various types of relay cores, armature yokes in electrical and telecommunications equipment; core materials for strong electromagnets; Yaoqiang pure iron; magnetic components for instruments and meters; cores and casings for DC motors; 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 purity of steel quality. 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 has a carbon content ≤0.004%, providing reliable conditions for simplifying and shortening the annealing process of parts.

3) Good cold and hot working performance. Cold working such as turning, upsetting, punching, bending, drawing, etc., poses 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, such as sheet thickness ≤1.5mm, thickness tolerance ≤0.03mm; sheet thickness >1.5mm, thickness tolerance ≤±0.05mm.
