18
Q

What is a ferrous metal

A

A metal containing mostly iron and carbon.

They are magnetic and will rust

19
Q

What is a non ferrous metal

A

A metal that doesn’t contain iron

Noy magnetic and doesnt rust

20
Q

What is an alloy

A

It is a mixture if two or more metals or combining two or more elemts providing thta one is a metal

21
Q

What is a hardwood

A

Wood from a broad leafed (deciduous) tree, these trees are generally slow growing

22
Q

What is a softwood

A

Wood from a coniferous (cone baring) tree. These trees tend to grow fast and are evergreen

23
Q

What is a manufactured board

A

A man made wood based composite material.

24
Q

What is a thermoplastic

A

A material which can be repeatedly reheated and reshaped, allowing it to be recycled after its initial use

25
Q

What is thermosetting plastic

A

A material when heated gows under a chemical change where the molecules form rigid cross links, thus means it cannot be reheated and reshaped.

26
Q

What is an elastomer

A

A material when at room temperature can be deformed under oressure and upon release of oressure will return to its original shape.

27
Q

What are paper and boards

A

They are complient materials, meaning they can be scored, folded and cut to form nets for packaging

28
Q

What is a composite

A

A material comprised of two different materials to enhance its propeties

29
Q

What is a smart material

A

A material whose physical propeties change in response to an input or output change in the environment such as electricity, pressure, temperature or light

30
Q

What is a modrrn material

A

A material developed through the invention of new or improved processes
