Common classifications of electrical materials are as follows:

Electrical materials are divided into four categories: conductive materials, magnetic materials, insulating materials and structural materials.

(1) According to the classification of Engineering materials, they can be divided into metal materials (including ferrous metal materials and non-ferrous metal materials) and non-metallic materials (including gas materials, solid materials and colloidal materials).

(2) According to the chemical composition of the material. It can be divided into inorganic materials, organic materials and inorganic organic composite materials.

[3] According to the functional classification of materials, they can be divided into conductive materials, resistive materials, magnetic materials, insulating materials, lubricating materials and construction materials.

There are also eight categories of electrical materials: they are steel. Non-ferrous minerals and their products, chemical materials, pigments, dyes, lacquers and plastics, electrical fittings and tools, gauges and instruments of animal and plant forests and their products, etc.

All kinds of classification methods have certain reasons, and different classification materials can be selected according to the specific situation.
