**Unit 6 Materials properties
Metals
iron
strong
can be use for bridges
gold
shiny and expensive
it is used for jewellery
stainless steel
does not rust , strong and conducts heat
it can be used for pans
copper
conducts electricity and flexible
used for electrical wiring
mercury
the only liquid at room temperature
properties
metals are shiny when they are polished or freshly cut
metals ring like a bell when you hit them
they do not shatter or crack
metals can be shaped by bending them
they can hold large weights without breaking
metals can be malleable, means that they can be hammered into shape
metals can be ductile, means they can be drawn out into wires
some metal are magnetic
metals are good conductor of heat
the surface of metals will be dull after a while
big lump of metal are hard to test for bendiness
Non-metals
properties
non-metals look dull
non-metals solids are brittle
non-metals does not conduct heat or electricity well
non-metals that are not gases have low melting points
non-metals are not as strong as metals
many non-metals are gases
plastic
light
cheap
flexible and easily shaped
Don't react with food
fibres
soft
strong
bendy
ceramics
strong
brittle
glass
transparent
very brittle
can be coloured
Don't react with food
