Metals all have similar properties
eg have high melting points
They are all solid at room temperature
except for mercury!

Most metals are dull on the surface, but shiny when cut or polished.
The metal surface reacts with oxygento make a dull coat.

Both heat and electricity flow easily through metals

Steel is a very strong metal.It is made when iron is mixed with carbon.

metals are tough and malleable (change shape easily)
tungsten melts at 3410 C
Mercury freezes at -40C

Aluminium is a very lightweight metal.It has a low density
and does not easily corrode.
Pure aluminium is weak and soft.
Aluminium and magnesium alloy is stronger, harder and stiffer.

Stainless steel does not rust, but it’s expensive.
Nickel and Chromium mixed with iron make this alloy.
