Tungsten has been found in medieval
   Damascus swords-so hard they
could cleave iron spears at a blow, so
keen they could cut floating gossamer,
so elastic they would spring back to
shape after being bent to a right angle.
Yet it is only for about 50 years that
tungsten has been known as a valuable
alloying metal.
2 The exciting flash of gold was the
   dream of miners in gold rush days.
They cursed when their pickaxes rang
against a stubborn black rock-one of
the tungsten ores, which has since sold
for as much as gold ores. Tungsten ore
is mined in the United States and
many other countries throughout the
world.
3 Tungsten (which is Swedish for
   "heavy stone") gets hotter than any
other metal before it melts-6,1000 F.
That's why it is used in electric lamp
filaments and has many valuable indus-
trial applications where high heat resist-
ance is needed. Electromet produces
pure tungsten powder, ferrotungsten,
and calcium tungstate.
Help Wanted?
If you need help on some specific
application of ferro-alloys or alloy
steels, let Electromet work it out
with you. Our modern, completely
equipped research laboratories at
Niagara Falls, New York, are staffed
by men who have had years of ex-
perience in helping ferro-alloy users
In cutting tools of high-speed steel   Nature made the diamond, but man
   and tungsten carbide and in the well-
known HAYNES STELLITE non-ferrous
alloys, tungsten produces a hard edge
that stays hard even under extreme
friction and high temperatures. Tung-
sten has other important uses, such as in
the heat-resisting metals of gas turbines
and jet engines.
