1. PHYSICAL PROPERTIES

   • Electric properties
     • Insulation: some don´t conduct the electricity
     • Conductivity: electricity flow
   • Thermal properties
     • Conductivity: heat flow´s through it
     • Swelling: materials increase its volume
   • Optical properties
     • Transparency: you can see other materials through this
     • Translucency:materials allow light to pass through them
     • Opacity: the materials don´t allow light to pass
     • Luster: how shiny the substance looks
   • Acoustic properties
     • Isolation
     • Conductivity
   • Mechanical properties
     • Fragility-tenacity
     • Hardness
     • Flexibility-rigidity
     • Elasticity-plasticity

2. CHEMICAL PROPERTIES

   • Oxidation: corrosion of a metal
   • Solubility: ability of a solid to be solved into a liquid

3. TECHNOLOGICAL PROPERTIES

   • Welding capability: the union of materials
   • Ductility: the material can be enlarged
   • Hardness: ability to withstand surface indentation
   • Malleability:a substance can be flattened
