In the industrial world, where precision control and efficient conversion are paramount, a material called DT4C electromagnetic pure iron is quietly becoming a core pillar of many high-end devices, particularly in Relay Yoke Plate. DT4C is not an ordinary metallic material; it is the highest-performance grade in the DT4 series of electromagnetic pure iron, with extremely stringent standards for its technical requirements and performance.
The superiority of this material is primarily reflected in its exceptional electromagnetic properties: extremely low coercivity (Hc) (≤32 A/m) and extremely high maximum permeability (μ) (≥0.0151 H/m), which are critical characteristics for the Yoke for Electromagnetic Relay. This means that DT4C responds extremely sensitively and efficiently to applied magnetic fields, enabling rapid and precise electromagnetic conversion with minimal energy loss (hysteresis loss and eddy current loss) during the process.
DT4C's Exceptional Performance
DT4C electromagnetic pure iron stands out in high-end manufacturing thanks to its series of superior properties:
Excellent Electromagnetic Performance: DT4C features low coercivity, high permeability, and high saturation magnetism, while maintaining magnetic stability and avoiding magnetic aging in Magnetic Yoke applications. This means that even with long-term use, its magnetism will not decay over time, ensuring long-term stable operation of the equipment.
High Steel Purity: DT4C has a dense and uniform internal structure with low gas content, and the finished product contains ≤0.004% carbon, making it ideal for Electrician Pure Iron Yoke. This extremely high purity lays a solid foundation for its stable electromagnetic performance.
Excellent Machining Performance: DT4C exhibits good cold and hot working properties, allowing for various cold working operations such as turning, pressing, punching, bending, and drawing of Electrician Pure Iron Strip Stamped components. During hot working, it has low red brittleness sensitivity and can be reforged and rerolled over a wide temperature range.
High surface quality and dimensional accuracy: DT4C can provide ultra-precision cold-rolled sheets suitable for Relay Yoke manufacturing. For sheets ≤105mm thick, the thickness tolerance can be guaranteed to be ≤0.03mm; for sheets >1.5mm thick, the thickness tolerance can be guaranteed to be ≤±0.05mm. It also possesses excellent welding and electroplating properties.
