SOFTWOOD (a solid wood) |
These are coniferous trees. They have pine needles and bare cones. They are evergreen so keep their needles in the winter. They are lighter coloured woods that are often knotty. They can be easier to work with and are quick to grow. This makes them cheap to buy. |
|
HARDWOOD (a solid wood) |
These are deciduous trees. They have leaves and loose them in the autumn. They are darker coloured woods that have a compact grain structure. They can be harder to work with because of this and take longer to grow. This makes them expensive to buy. |
|
MANUFACTURED BOARD (man-made) |
These are man-made. They are be made from wood fibres, chips and layers that are glued together. They are produced in large sheets and are a cheaper alternative to solid wood.
E.g MDF, Plywood, Chipboard, Hardboard... |
|
THERMOPLASTIC |
This becomes soft when heated which enables them to be shaped and formed. They return to a cooled/rigid state when cool and they can be re-heated and formed again and again.
E.g Acrylic and polythene. |
|
THERMOSETTING PLASTIC |
This becomes soft when heated which allows it to be shaped and formed but this can only be done ONCE! Good for making heat resistant plastic products.
E.g Urea Formaldehyde / Melamine Formaldehyde |
|
FERROUS METAL |
These materials contain Iron. This material can rust.
E.g Cast and Mild Steel grates in the road. |
|
NON-FERROUS METAL |
These materials do not contain iron. Which means they do not rust.
E.g Aluminium and Copper - Cans and bathroom taps. |
|
ALLOYS |
This is a mixture of two or more metals. Usually a pure metal with other elements to produce a 'tailor-made' metal with special properties. |
|
COMPOSITE
Particle Composites Laminate Composites Stranded Composites |
Materials that are produced by combing different materials to produce better properties.
