Introduction to Electrical-Pure Iron Grade DT4C
Our Grade DT4C represents the pinnacle of this category, combining ≥99.85% purity with meticulously controlled chemical composition. This section introduces the fundamental role of DT4C in modern industries, emphasizing its distinction from conventional iron alloys.
Chemical Composition & Physical Properties
A cornerstone of DT4C's performance lies in its elemental composition. Below is a detailed breakdown:
| Element | Maximum Concentration | Impact on Performance |
|---|---|---|
| Carbon (C) | ≤0.005% | Reduces hysteresis losses in magnetic cores |
| Silicon (Si) | ≤0.02% | Enhances electrical resistivity |
| Manganese (Mn) | ≤0.02% | Minimizes oxidation susceptibility |
| Sulfur (S) | ≤0.01% | Prevents embrittlement at high temperatures |
| Phosphorus (P) | ≤0.01% | Maintains dimensional stability |
| Iron (Fe) | ≥99.85% | Provides the ferromagnetic base |
Note: Trace elements such as Ni, Cu, and Al are kept below 0.03% to avoid lattice distortion.
Magnetic Characteristics Analysis
DT4C's superiority stems from its optimized magnetic properties:
Saturation Induction (Bs): 2.15 T (higher than standard soft magnetic materials)
Coercivity (Hc): ≤8 A/m (indicating low energy loss during magnetization cycles)
Remanence (Br): ≤0.05 T (enables rapid demagnetization)
These attributes make DT4C ideal for applications requiring high efficiency and minimal power consumption.
