Magnetite is a ferri-magnetic material with good thermal conductivity and heatable by microwaves. Inoxia holds stock magnetite powder in two grades.


This product is of natural origin, mined and processed in Sweden. It is a fine powder with a high density, suitable for making high density components, improving sound dampening, stabilisation and adding a quality feel.

The low cost, high density and ferri-magnetic properties makes it an excellent material for coil cores and other work with magnetism.

Synthetic micronized

A high performance micronized pigment. The predominant particle size is 0.2 microns with a lower density and higher purity than the naturally sourced material.
