Electrical Engineering

Magnetic Materials These materials play an important role for existence of various electrical machines. The magnetic materials having high permeability are used for building the core to from the low reluctance path for magnetic flux. Magnetic materials can be further divided in following categories -Ferromagnetic materials -Paramagnetic material -Diamagnetic materials -Antiferromagnetic materials -Ferrites

Electrical Engineering materials can be classified as below-Conductors Semiconductors Insulators Magnetic material

Ceramic materials  are non-metallic solids. These are made of inorganic compounds such as Oxides, Nitrides, Silicides and Carbides. Ceramic materials possess exceptional Structural, Electrical, Magnetic, Chemical and Thermal properties. These ceramic materials are now extensively used in different engineering fields. Examples: Silica, glass, cement, concrete, garnet, Mgo, Cds, Zno, SiC etc. Organic Materials All organic material are having carbon as a common element. In organic materials carbon is chemically combined with oxygen, hydrogen and other non-metallic substances. Generally organic materials are having complex chemical bonding.  Example: Plastics, PVC, Synthetic Rubbers etc.

Engineering materials can also be classified as below- Metals and Alloys Ceramic Materials Organic Materials

Ferrous Metals – All ferrous metals are having iron as common element. All ferrous materials are having very high permeability which makes these materials suitable for construction of core of electrical machines. Examples: Cast Iron, Wrought Iron, Steel, Silicon Steel, High Speed Steel, Spring Steel etc. Non-Ferrous Metals - All non-ferrous metals are having very low permeability. Example: Silver, Copper, Gold, Aluminum etc.
