Once airplanes were able to carry only their
pilots. Today they are a mighty commercial
factor—transporting pay-loads of almost incred
ible proportions to their own weight. Molyb
denum steels have contributed notably to the
lighter, stronger construction of these modern
Winged Mercuries of the air.
While the advantages of minimum weight
and maximum strength in airplanes are obvious,
they are not always fully appreciated in other
products. Take any machine. If made from infe
rior irons or steels, more weight is required.
This means more freight cost on material from
the steel mill, and on the finished machine to
the user; more power cost every time it is
moved; less "pay-load"; less service life.
What Moly irons and steels have done for
airplanes (in motors and structural parts), they
can do and are doing in automobiles, rail
way cars and ships; in engines and boilers; in
structural work; in farm, factory, mining, road-
building and oil-well machinery in ferrous
products of all kinds.
The story of Moly —"industry's most versatile
alloying element"-would fill a book. And
the interesting, non-technical brochure we have
waiting for manufacturing executives and their
associates is "Molybdenum in Industry." Write
for it. Climax Molybdenum Company, 500 Fifth
