ELECTRICAL PROPERTIES
Electrical conductor
Allows electrical current flow through material
(Good conductor - little resistance)
ELECTRICAL PROPERTIES
Electrical Insulator
Don’t allow flow of electricity through material
THERMAL PROPERTIES
Thermal conductor
Allows heat energy flow through material
(Good conductor - little resistance)
THERMAL PROPERTIES
Thermal Insulator
Don’t allow flow of heat through material
THERMAL PROPERTIES
Thermal expansion
Increase of material volume due to heat
OPTICAL PROPERTIES
Opaque - light can’t travel through
Translucent - light partially travels through
Transparent - light fully passes through
PHYSICAL PROPERTIES OF MATERIALS (4)
- Density - mass of material in a vol
- Fusibility - fused / converted to molten state
- Magnetism - iron/steel
- Corrosion resistant - resists wear
