Amorphous & Nanocrystalline Material Solutions

Amorphous & Nanocrystalline Magnetic Solutions

High Magnetic Performance. Compact Design. Application-Driven Solutions.

Metal Union supplies amorphous and nanocrystalline magnetic cores and soft magnetic materials for power electronics, energy conversion, EMI filtering and electrical protection.

With high permeability, high saturation flux density and low magnetic losses under suitable operating conditions, these materials can support compact, efficient magnetic component designs.

We support standard and customized magnetic cores, working with customers to match material properties, core geometry and performance requirements to their applications.

Products & Applications

Common-Mode Choke Cores

High-permeability nanocrystalline cores for EMI/EMC filtering in EV chargers, solar inverters, UPS systems and industrial power supplies.

Transformer & Inductor Cores

Amorphous and nanocrystalline cores for selected medium- and high-frequency power conversion applications where magnetic loss, operating flux density and thermal performance are critical.

Current Transformer & Residual Current Protection Cores

Magnetic cores for current sensing, metering and RCD/RCCB/RCBO applications, with magnetic characteristics selected according to sensitivity and operating requirements.

Amorphous & Nanocrystalline Ribbons

Soft magnetic alloy ribbons for transformer cores, inductive components and customized magnetic core manufacturing.

Engineering Support

The right magnetic core starts with the right application.

Core selection involves more than permeability. Operating frequency, current, flux density, temperature, magnetic loss and available space all influence the final design.

We work with customers to review these requirements and identify suitable materials, core dimensions and magnetic characteristics.

For existing designs, we can also evaluate whether an amorphous or nanocrystalline alternative offers potential improvements in size, loss or magnetic performance.

Quality & Performance Consistency

Consistent performance matters from sampling to repeat production.

Material composition, ribbon quality, core winding and annealing conditions can influence magnetic properties.

We focus on identifying critical requirements before production, coordinating process controls and verifying magnetic performance against agreed specifications.

Depending on the product and application, inspection may include dimensional checks, permeability, core loss and other relevant magnetic characteristics.
