1. Product Introduction

Our Iron-Based Amorphous Alloy Cores are made from ultra-thin amorphous ribbons (20–30µm) via precision winding and optional post-processing. Compared with traditional grain-oriented silicon steel cores, they feature ultra-low core loss, high magnetic permeability, and compact size — ideal for energy-efficient power systems.

2. Key Advantages
Feature Performance Benefit
Ultra-low no-load loss Only ~1/5 of silicon steel cores, reduces long-term energy costs
High saturation flux density (~1.56T) Enables smaller, lighter component designs
Wide frequency range Suitable for 50Hz distribution to high-frequency power electronics
Low noise & low magnetostriction Ensures quiet, stable operation in sensitive environments

3. Customizable Processing Options
 
We offer 4 core processing variants to match your application requirements:
Process Type Description Best For
Non-Annealed Raw wound core, no heat treatment Low-cost, non-critical applications with basic magnetic performance needs
Annealed Precision heat-treated to optimize magnetic properties Standard transformers, inductors requiring stable permeability and low loss
Epoxy Coated Encapsulated with epoxy resin for insulation & mechanical protection Harsh environments, high humidity, or vibration-prone installations
With Housing (Cased) Pre-assembled in plastic/metal enclosures, ready for direct use Fast integration into modules, common-mode chokes, and compact power supplies

4. Core Specifications (Standard Toroidal Cores)
Parameter Typical Value
Material Fe-based amorphous alloy (1K101 grade)
Ribbon Thickness 25µm (standard)
Saturation Flux Density (Bs) 1.56–1.59 T
Core Loss (Pcv) ≤0.2 W/kg @ 50Hz, 1.3T
Operating Temperature -40°C ~ +130°C
Available Shapes Toroidal, rectangular, C-core, oval, custom profiles

5. Typical Applications

 
  • Energy-efficient distribution transformers (low-loss grid infrastructure)
  • Solar/wind power inverters and PFC inductors
  • Electric vehicle chargers and on-board power systems
  • Common-mode chokes for EMI suppression
  • Precision current transformers and power filters

 FAQ

Q1:What are the differences between annealed and non-annealed amorphous cores?
A:Annealed cores undergo strict heat treatment to release internal stress, achieving lower loss and higher stability, suitable for high-standard energy-saving equipment. Non-annealed cores are more cost-effective for ordinary applications.
Q2:Why choose epoxy coated amorphous cores?
A:Epoxy encapsulation provides excellent electrical insulation, dustproof, moisture-proof and anti-vibration performance, ideal for outdoor, humid and industrial harsh environments.
Q3:Do you support custom specifications?
A:Yes, we provide full custom service on size, shape, winding and surface treatment to match your unique design requirements.
Q4:Can I get free samples?
A: We support sample testing for serious project cooperation. Please contact us to confirm your technical parameters.
