Physical Properties
Dimensions:-
- This includes size, shape , tolerance on materials.
Size is determined by breadth, width, length, diameter, etc.
Shape is determined by section of the material like square, circular, triangle, I, channel, angle, etc.
(B)Density:-
Density is defined as the weight per unit volume of the materials. For metals it can be calculated as
Density = nA/a3N

Tensile strength:-
- It is measures the force required to pull something such as rope,wire or a structural beam to the point where it breaks
Ductility:-
–It is measure of how much strain a material can take before rupturing
Malleability:-
-It is the property of a material that can be worked or hammered or shaped without breaking

Mechanical Properties
Brittleness:-
It is breaking or shattering of a material when subjected to stress (when force is applied to it)
Toughness:-
–It is the ability of a material to absorb energy and plastically deform without fracturing
Hardness:-
-It is the property of being rigid and resistant to pressure; not easily scratched

Magnetic Properties
Magnetic permeability:-
-The ratio between inductance or magnetization and magnetic field. It is a measure of the ease with which magnetic flux lines can ‘‘flow’’ through a material.
Magnetization - The total magnetic moment per unit volume.
Magnetic susceptibility - The ratio between magnetization and the applied field.
