Properties (materials)
Properties (materials)
Characteristics of materials that determine how they perform
Two main types of properties
Two main types of properties
Physical properties and working (mechanical) properties
Physical properties
Physical properties
Characteristics observed without changing material's composition
Absorbency
Absorbency
How well a material can soak up liquids
Density
Density
How much mass a material has in a given space
Fusibility
Fusibility
How easily a material melts when heated
Electrical conductivity of metals
Electrical conductivity of metals
Excellent conductors, e.g., copper used for wires
Thermal conductivity of polymers
Thermal conductivity of polymers
Poor heat conductors, good for insulation
Hardness
Hardness
Resistance to scratching, denting, or wearing away
Toughness
Toughness
Ability to absorb impacts/shocks without breaking
Malleability
Malleability
Can be hammered/pressed into shapes without breaking
Ductility
Ductility
Can be stretched/drawn into thin shapes without breaking
Elasticity
Elasticity
Can bend/stretch then return to original shape
