SMI Soft-Magnetic Billet | Xinye Taiming - Nano-Crystalline Structure & Extreme Temperature Stability
Meta Description: Xinye Taiming's SMI billets feature 99.98% Fe purity, anisotropic permeability (μ=25k-45k), and MIL-STD-2073D compliance. Engineered for aerospace & next-gen EV systems.
Core Innovation
Xinye Taiming revolutionizes soft-magnetic technology with SMI-α phase control – a patented nano-structuring process achieving 15nm grain size uniformity. This breakthrough enables:
✔️ Zero-crossing hysteresis (<0.2% B-H loop tilt)
✔️ Multi-axial permeability (X/Y/Z axis variance ≤8%)
✔️ Self-passivating surface (Cr-free oxidation resistance)
