PROPERTIES OF
MATERIALS

LEARNING OBJECTIVES
At the end of this session, the students
must be able to:
1. Enumerate the different properties
2. Recognize and differentiate the
various properties of materials.

• Different materials have different properties and it
is essential for the selection of what material to
use for a particular application. They can be
classified into:
1. Physical
2. Electrical
3. Chemical
4. Thermal
5. Mechanical

1. Physical properties – such as shape, size,
color, etc.

PROPERTIES OF MATERIALS
2. Electrical properties – such as conductivity,
resistivity, dielectric strength, etc.

PROPERTIES OF MATERIALS
3. Chemical properties – such as composition,
atomic weight, molecular weight, etc.

PROPERTIES OF MATERIALS
4. Thermal properties – such as thermal expansión,
thermal conductivity, etc.

PROPERTIES OF MATERIALS
4. Thermal properties – such as thermal
expansión, thermal conductivity, etc.

PROPERTIES OF MATERIALS
5. Mechanical properties
– properties which give the response of
the material under
