METALS
DEFINITION:
A
metals are lustrous
elements that are good conductors of heat and electricity.
Metals
come from the rocks and they can be in many different colour.
TYPES OF METALS:
Ferrous:
Ferrous
metals are
those ones that contain iron.
Steel:
Used
for engineering purposes and in general, none specialised metal
products.
Cast
Iron: Used
to manufacture items such as engine blocks and manhole covers.
Wrought
Iron: Used
to make items such as ornamental gates and fencing. Wrought iron is
very soft and magnetic.
Non-Ferrous:
Non-ferrous
are
those ones that don't contain iron.
Examples:
Lead:
Used
in roofing,
in batteries and to make pipes.Lead
is soft and ductile.
Silver:
Used
for decorative in jewellery and ornaments, and to solder different
metals together.
Silver
is a good electrical conductor
Copper:
Used
for wiring, tubing and pipe work. Copper is a very good conductor of
electricity.
Brass:
Used
for ornamental purposes and within electrical fittings.
Brass is a hard metal.
Aluminium:
Used
in aircraft manufacture, window frames and some kitchen ware.
Aluminium
is corrosion resistance.
An alloy is a mixture of metals or a mixture of a metal and another
element
Non-ferrous
alloys: Brass and Bronze
Ferrous
alloys: Iron-Hydride
News
materials:
*Microlattice:
It
is the lightest metal now a days.
*Super
Hard Metals: The
material is four times harder than pure titanium and has
applications in making longer-lasting medical implant
