Unformatted text preview: Types of Materials •  Metals: –  Strong, duc4le –  High thermal & electrical conduc4vity –  Opaque, reflec4ve. •  Polymers/plas4cs: covalent bonding –  SoD, duc4le, low strength, low density –  Thermal & electrical insulators –  Op4cally translucent or transparent. •  Ceramics: ionic bonding (refractory) – compounds of metallic & non- metallic elements (oxides, nitrides, carbides) –  BriNle, glassy –  Non- conduc4ng (insulators) •  Composites: –  Composed of two or more individual materials (metals, ceramic, and polymers) –  Proper4es are varied Material Proper4es [1] Mechanical (Force > Deformation) [2] Electrical (Electrical Field > Conductivity) [3] Thermal (Heating > Heat Capacity/Thermal Conductivity) [4] Magnetic (Magnetic Field > Attraction/repulsion & magnitude of response) [5] Optical (Light > Reflection/Refraction) [6] Deteriorative (e.g. Chemical Exposure > Breakdown) Electrical Materials T...
