2. Metals

   • Ferous
     • Steel
     • Contain Iron
     • Tough
     • Ductile
     • Malleable
     • Poor resistance to corrosion
   • Non-ferous
     • Aluminium
   • Alloys
     • Stainless Steel
       • Iron mixed with Carbon and Chromium

3. Plastics

   • Thermosetting
     • Mouldable when heated
     • Retain shape when cooled
     • Can only be shaped once
     • Epoxy Resin
       • Good electrical insulator and resists chemicals well
         • Adhesives
   • Thermoplastics
     • Can be reshaped when heated
     • Recyclable
     • Polypropylene
       • Light and good resistance to chemicals
         • Medical equipment
     • Less durable than thermosetting plastics once cooled

4. Composite materials

   • Made by combining a reinforcing material such as wood pulp, and a bonding agent, such as glue
   • MDF

5. Ceramics

   • Made from clay, sand and feldspar
   • Materials are ground to a fine powder, mixed together and fired at high temperatures (700-2000°C)
