Materials properties

Materials properties

1. Physical properties

   • Electric
     • Conductivity: electricity flows.
     • Insulation: some of them don´t conduct
   • Thermal
     • Conductivity:the heat flows
     • Swelling:materials increase its volumen by heat
   • Density
     • M/V
   • Permeability
     • Liquids flow through some materials
   • Optical
     • Transparency:can see other objects
     • Translucency:the ligh through the objects
     • Opacity:the light does not pass through the materials
     • Luster:the shiny of the substance
   • Mechanical
     • Hardness:withstand scratches on the surface
     • Fragility-Tenacity:resistance to the impacts
     • Elasticity-Plasticity:deformation by an effort
     • Flexibility-Rigidity:the possibility of being bended
   • Acoustic
     • Isolation
     • Conductivity

2. Chemical properties

   • Oxidation
     • Is the corosion of a metal by the oygen effect
   • Solubility
     • The ability of a solid to be solved into a liquid substance

3. Technological properties

   • Hardness
     • Ability to withstand surface indentation
   • Malleability
     • if a surface can be flattened
   • Ductility
     • The material can be enlarged to form filaments under tensile load
   • Welding capability
     • Union of materials by partial fusion
