  • Materials and ManufacturingMaterials have different properties, limitations, and durability.

    Selecting the appropriate material for a product is an essential task.

    Materials can be generally classified as Natural, Synthetic, or Mixed Raw or Processed

  • Materials and ManufacturingSelecting the appropriate material is based on three qualifications:

    The material type and the functionThe manufacturing process, quantity, and costSustainability

  • Material TypesMetals are elements, compounds, or alloys that account for roughly two-thirds of all materials and have properties that include:Strength, ductility, high melting point, thermal and electric conductivity, and toughness Metals can be easily bondedthey have free electrons that can easily move from one atom to the next.

  • Material TypesCeramics are an inorganic and nonmetallic material formed from powdered materials through the application of heat and have properties that include: Strength, hardness, resistance to high temperatures, often brittle, and depending on how the product is formed, dense or lightweight, conductive or not, magnetic or not

  • Material TypesPolymers are commonly referred to as plastics or rubber. Plastics are group of synthetic materials that are formed or molded into shape.Rubber can be easily deformed and return to its near original shape.Polymers often resist corrosion, resist conduction, and are less dense than metal or ceramics. 2013 International Technology and Engineering Educators Association STEMCenter for Teaching and Learning Foundations of Technology

  • Material TypesPolymers are divided into two categories:Thermoplastics materials that can be melted or re-melted and then molded or extruded into a product (polyethylene, polypropylene)Think ChocolateThermoset plastics materials that are set using heat or a chemical reaction. These materials cannot be re-melted. (resins, epoxies)Think Eggs or Cake 2013 International Technology and Engineering Educators Association STEMCenter for Teaching and Learning Foundations of Technology
