Cobalt-based amorphous/nanocrystalline magnetic core

Cobalt‑based amorphous and nanocrystalline magnetic cores are manufactured using ultra‑thin cobalt‑based alloy ribbons as the base material. They undergo precision winding, high‑temperature crystallization and curing, followed by insulating encapsulation and shaping, and are available in two structural configurations: solid rings and high‑precision cut sections. These products boast core advantages such as exceptionally high initial permeability, extremely low coercivity, near‑zero magnetostriction, low losses at high frequencies, minimal temperature drift, and high sensitivity. They are well suited for demanding applications including high‑frequency operation, precision measurement, weak‑signal acquisition, and EMI filtering. Customizable dimensions, air gaps, and magnetic performance parameters further enhance the measurement accuracy and long‑term operational stability of precision electronic devices.
 

Features and Advantages

  • The substrate, a cobalt-based alloy, exhibits extremely low magnetic anisotropy, with a coercivity of ≤0.5 A/m, very low hysteresis losses, and negligible temperature rise under high-frequency operating conditions.
  • The initial permeability can reach the order of 10⁵, with a gentle decline in permeability across a wide frequency range, strong capability for detecting weak magnetic field signals, and high measurement accuracy.
  • The magnetostriction coefficient approaches zero, offering resistance to vibration and stress-induced disturbances; its magnetic properties remain stable across high and low temperature ranges, with output exhibiting no drift.
  • The rectangular ratio is controllable, allowing for high‑aspect‑ratio specifications; it offers leakage protection and exhibits sensitive triggering and fast response in magnetic amplification applications.
  • The molded structure is dense and exhibits high mechanical strength, supporting both solid-ring and split‑ring configurations; outer diameter, inner diameter, height, and air gap are all customizable.
  • Compared with ferrites and permalloys, it offers superior high-frequency filtering performance and a more compact footprint, making it well-suited for miniaturized, precision component designs.

 

Typical application areas

  • Precision current transformers, leakage-current protection magnetic rings, and smart metering cores;
  • Magnetic fluxgate sensors, weak magnetic field detection, and high-precision industrial sensor cores;
  • High-frequency common-mode inductors, EMI filter inductors, magnetic amplifiers, and switch-mode power supply spike suppressors;
  • Communication RF equipment, precision in-vehicle electronic control systems, compact power supplies for the defense industry, and magnetic components for instruments and meters;
  • Photovoltaic energy storage testing module, precision sampling for charging piles, and magnetic cores for industrial control signal acquisition.
