PROPERTIES OF MATERIALS (GROUP 2)
thermal properties
Melting point= The property of a material to change state with increasing temperature.
Thermal conductivity= The property of a material to conduct heat.
Thermal expansion= The material change in shape,area and volume when temperature increas.
mechanical properties
strength=
the ability of the material to resist forces without breaking, bending or changing permanently
Hardness=
the ability of a material to resist scratching, abrasion and indentation
Elasticity=
the ability of the material to return to its original shape when a force is removed
Plasticity=
the ability of a material to be deformed permanently without breaking or fracturing
Ductility=
the ability of a material to be deformed plastically when it is stretched
Malleability=
the ability of a material to be deformed plastically when it is compressed
Stiffness
the ability of a material to resist deformation in response to an applied force on load
Toughness=
the ability of a material to resist shock or impacts and plastically deform without breaking
Brittleness=
the tendency of a material to break under stress before it deforms
Fatigue=
the ability of a material to repeated stress cycles
electrical-magnetic properties
Electrical conductivity= When a material conduct electricity.
electrical resistivity= the opposition of a material to the flow of electric current
chemical properties
Corrosion resistance= the ability of a material to resist oxidation by atmosphere.
