more uses are being found for that re-
markable metal, aluminium. according
to the United States geological survey
and recent United States consular re-
ports. The production and expectation
OF the metal so far as the United
states Is concerned are rapidly in
stantly multiplying.
Multitudinous uses are being found
for aluminium combining as it does
both lishtness and stiffness. Because
Of both these qualities, It is in con-
stant1y increasing use In the motor car
industry. It's utilization for motor car
purposes 10 Of especial interest in it's
application to the art Of aviation. The
qualities Of lightness and stiffness es-
pecially recommend It for service in
the construction of airships and the
construction Of motors to be used in
airships.
In the making Of castings, 1t has
been found advantageous to alloy the
metal with copper, zinc or nickel which
increases its strength and makes 1t
easier to work. The principal demand
for such castings comes from auto
mobile builders. The users Of brass
castings. especially the manufacturers
Of electrical apparatus, have been
gradually changing from brass to
aluminium castings and for some pur-
poses aluminium castings have been
substituted for those Of iron. according
to the Geological Survey. The use Of
zinc for hardening purposes has been
condemned by some writer's and up
held by others.
Recent reports Of the Geological
Survey in discussing aluminium, say It
is one Of the most malleable Of metals.
Moreover. 1t takes and retains a very
high polish. For these reasons 1t Is
used in connection with the manufac-
ture OF articles Of everyday use almost
without limit.
Some Of these new uses are as wall
paper" ceiling panels. stamped or
hammered trays. finger plates and the
like in the form Of very thin sheets;
as substitute for lithographic stones
and zinc plates. and in the panels Of
car and carriage bodies. The advant-
age of aluminium in the manufacture
OF cooking utensils il well known.
Among these advantages are long life,

Great strides have been made in the
study of. alloys Of aluminium in recent
years. The alloys in most common use
are those Of aluminium combined with
zinc nickel and copper. "A new alloy
which has attracted attention il known
as magnalium. Two to twelve parts OF
magnesium added to 100 parts Of alum
mum produce an alloy lighter than
aluminium and possessing the worka-
hility and strength Of brass. One OF
the most valuable features Of the alloy
Is the ease with which It can be turn.
ed. planed or drilled The value of
aluminium In refining iron and steel
and in connection with iron and steel
manufacture In general is constantly
increasing thru the researches and In
ventions Of scientists who are explor-
ing the possibility Of the aluminium in
dustry.
The value Of the exports from the
United States Of aluminium and Of
manufactures Of aluminium of domes-
tic production has Increased from
about 100000 in 1907 TO about mil
lion a year. The domestic production
is growing rapidly. Aluminium is worth
from about $3.50 TO s4s2 per ton, ac-
cording to the latest quotations.
