Questions and Answers with Verified
Solutions | Latest Updated 2026
Ferrous Metals Metals that have iron as the major
ingredient and
are usually magnetic
Tool Steels or High-Speed Steels Very high carbon steels often used to
make
punches, dies, shear blades, cutting tools
and other
components
Non-ferrous metals Metals that do not have iron in large
enough
amounts to have any major influence on
the
properties of the metals and are usually
non-
magnetic (with the exception of nickel)
Pure Aluminum Metal that oxidizes rapidly. Often has a
thin oxide
film covering. Smooth silvery surface
,Steels and Cast Irons Metal that is usually a silver-grey to grey
colour
depending on how the manufacturer
formed and
finished the metal
White/Grey Cast Iron Metal with a rough, dull grey surface
appereance
Malleable Cast Iron Smoother metal that white/grey cast iron
with
lighter grey colour
Copper and Brass Metal that is red or yellow in colour
depending on
the alloys in each
Nickel White to grey-coloured metal with a
smooth
velvety texture
Lead Very soft, malleable, bluish-grey metal.
Can be
scratched with your fingernail.
Hot-rolled Steel Steel that has a black mill scale or heat
scale
surface
, Cold-rolled Steel Steel with a shiny smooth suface and
finished to
more precise dimensions.
