Micrometals – Global leader in iron powder cores

Micrometals, Inc. established in 1951, is committed to supplying high quality iron powder cores to meet the needs of the electronics industry. Micrometals is an engineering driven organization offering powder core solutions with the widest catalog selection of materials, sizes and shapes and the ability to also quickly provide custom geometries and customized materials to suit specific application requirements.

In addition to the standard core catalog items, Micrometals will gladly produce custom shapes and sizes. Several key benefits of iron powder as a core material are:

  1. custom and proprietary tooling are relatively inexpensive,
  2. special prototypes can be machined from blocks of material for preliminary evaluation,
  3. cores can be manufactured in a variety of heights from any of the materials shown without additional tooling charges.

Signal processing

The main applications for signal processing are telecom line filters, proximity sensors, signal and pulse transformers, delay lines and antennae.

Ferroxcube offer outstanding technologies and products for telecommunications equipment manufacturers. For example, Ferroxcube have introduced the high-permeability material 3B46 for filter applications with high bias current. In combination with the virtually unlimited core shape variety offered by Ferroxcube, almost any technical challenge can be addressed.
