Engineering material properties

Engineering material properties

1. Physical

   • Mass: is the amount of matter in a body. Density = mass / volume
     • Weight:The weight of an object is the force that it exerts on a surface
       • Electrical Conductivitymeasure of how well a material accommodates the movement of an electric charge
         • Electrical Resistance: quantity that measures how the device or material reduces the electric current flow through it.
           • Magnetic Properties: will the product build up a magnetic flux in its material ?
   • Optical Properties
     • Transparent, opaque or translucent. what process? will the colour be added with a surface treatment?
   • Temperature Properties
     • Melting Point: WIll high temps be needed for the product?
       • Ductile to brittle transition temp: Will your product go through this transition>
         • Specific Heat: Will the product hold its temp needed?
           • Thermal Expansion: response to heating and contract on cooling
             • Thermal conductivity: is the property of a material to conduct heat. (W/mK)
