Resumen del Recurso

Resistant Materials
  1. Woods
    1. Hardwoods

      Nota:

      • A more expensive wood that comes from deciduous trees and it takes longer to grow. has a higher value as it looks nicer, is stronger and takes a long time to grow.
      1. Beech

        Nota:

        • A good firewood, medium weight, high abrasion resistance and is very tough. can warp in the presence of moisture fluctuations
        1. Oak

          Nota:

          • Hard, heavy but also fairly elastic. it is very resistant to weathering and moisture.
          1. Ash

            Nota:

            • Excellent firewood, heavy and hard similar to oak, high abrasion resistance and elasticity.
            1. Mahogany

              Nota:

              • very compact dark coloured wood with little pockets. Used as a veneer because it is very expensive
              1. Teak

                Nota:

                • high in oil and rubber content. one of the hardest and toughest hardwoods there are. It is resistant weathering and rotting
              2. Softwoods

                Nota:

                • Used for cheaper products being made on a large scale. grows from coniferous trees and grows fast
                1. Scots pine
                  1. Parana pine
                    1. Western red cedar
                      1. Pitch pine
                        1. Yew
                          1. European redwood pine
                        2. Metals
                          1. Ferrous

                            Nota:

                            • Metals that contain iron
                            1. Cast iron

                              Nota:

                              • A steel containing more than 2% carbon is named cast iron and is used with
                              1. Mild steel

                                Nota:

                                • Mild steel contains 0.05% to 0.3% making it both malleable and ductile.
                                1. Carbon steel

                                  Nota:

                                  • Carbon affects the properties of steel because it can increase brittleness and hardness making it suitable for drill bits and other tools.
                                  1. Stainless steel

                                    Nota:

                                    • Doesn't rust easily so us used in cutlery. A chromium layer too thin to see stops rusting  
                                  2. Non-ferrous

                                    Nota:

                                      Nota:

                                      • Good ductile properties which means it is good for wiring as it also conducts electricity well
                                      1. Alumnium

                                        Nota:

                                        1. Zinc

                                          Nota:

                                          • is brittle but becomes malleable at temps of 150^C. very resistant to corrosion and weathering so is used on bin covers. stops steel from rusting by galvanation

Batch production is when a series of identical products are made in small or large quantities. Another series is produced after Mass production involves worker producing large quantities of goods on a production line conveyor belt.
