TOUGHNESS: This is the resistance of a material to being broken when we strike it.
DEFORMABILITY: This is the ability of a material to be deformed.
DUCTILITY:  This is the ability of a material to be estreched into a wire.
MALLEABILITY: This is the ability of a material to be pressed or rolled into a sheet.

Good in the longitudinal direction and poor in the transverse direction.
Compressive strength
(resistance to being crushed)
It is better in the transverse direction than in the longitudinal direction.
Flexural strength
(resistance to being bending).
It is good but better in the transverse direction (e.g. posts and beams)(structures )
Hardness
This can vary a lot.
E.g.Wood is not very hard and this makes it easier a lot
(furniture, houses, boats ,etc.)
Toughness
It is used in sports equipment.(E.g. hockey sticks, baseball bats,etc)
Thermal and electrical conductivity
It is very low.
Sound conductivity
Good. It is used for musical instruments, e.g. guitars.
Colour
Different colours. (E.g. red, yellow, brown, etc.)
Density
Wood is a light material. (E.g. build ships)

STEEL: Is a ferrous material made mainly from iron with 0.1% to 2% carbon.
CAST IRON: Is made from iron and 2% to 6.67% of carbon.]]> 2018-11-30 13:01:32 UTC https://padlet.com/marisolmolo/1asandrataripaulagomez/wish/309738006 marisolmolo https://padlet.com/marisolmolo/1asandrataripaulagomez/wish/309741321 COPPER: It is a very good conductor of heat and electricity, it haghly resists to corrosion and it is very ductile and malleable( and easy solder).
TIN: It is very ductile and malleable when cold, easy to work with and melting it ( used for soft soldering). 
ALUMINIUM: It is a very light material, it is resistance to corrosion, and good conductor of heat and electricity. It is non-toxic, ( used for food packing) .It is a very ductile y malleable .It is  easy to shape.
ZINC:It is malleable and ductile .It is a good conductor of heat and electricity .It is a highly resistant to corosion and rust.]]> 2018-11-30 13:09:51 UTC https://padlet.com/marisolmolo/1asandrataripaulagomez/wish/309741321
