UNE-EN 60404-1:2017

This standard is intended to classify commercially available magnetic materials.

The term "magnetic materials" denotes substances where the application requires the

existence of ferromagnetic or ferrimagnetic properties.

In this standard, the classification of magnetic materials is based upon the generally

recognized existence of two main groups of products:

soft magnetic materials (coercivity d"1 000 A/m);

hard magnetic materials (coercivity >1 000 A/m).

Within these main groups, the classification when appropriate recognizes the following

characteristics:

the main alloying element and the metallurgical state and physical properties of the

material;

when possible and convenient, the relationship between these characteristics is identified.

A classification by specific areas of application cannot be applied to all materials because

different materials can very often be used for the same application depending on the

characteristics required.
