Taiyuan Yaoqiang Pure Iron Co., Ltd. – The DT4/DT4A/DT4E/DT4C series pure iron steel plates are important categories of electromagnetic pure iron, primarily used in precision magnetic components such as electronic elements, relays, and solenoid valves. Below is specific information: Yaoqiang Pure Iron – Composition and Characteristics The DT4 series contains ≥99.5% iron, ≤0.01% carbon, with low sulfur and phosphorus content (S≤0.01%, P≤0.02%). It features high magnetic permeability (μ), low coercivity (Hc≤96 A/m), and high saturation magnetic induction (Bs). Its electromagnetic performance is stable, with low red-shortness sensitivity, making it suitable for complex stamping processes. Yaoqiang Pure Iron – Product Forms Includes cold-rolled thin plates (0.5-3.5mm), hot-rolled plates (4-20mm), and medium-thick plates (8-180mm), with high surface finish and capability for processing complex shapes. Yaoqiang Pure Iron – Application Fields Electronic Components: Relay cores, solenoid valve cores, sensor magnetic components; Industrial Equipment: DC motor cores, automotive brakes, magnetic shielding materials; Precision Processing: Complex stamped parts, cold heading, cold drawing, etc. Yaoqiang Pure Iron – Typical Specifications Cold-rolled plate thickness: 0.5-3.5mm, hot-rolled plate thickness: 4-20mm, medium-thick plate thickness: 8-180mm. Different grades (e.g., DT4C, DT4E) are suited for specific scenarios due to compositional differences; for example, DT4C offers better stamping performance, while DT4E has more prominent electromagnetic properties.
