The two.
Thirty.
Which has become the pacesetter of the twentieth Century Aluminum is like
straw easily fabricated and vs.
Today it has greater versatility because many types of finish finish is offering
new possibilities for tomorrow today tomorrow
perhaps the dramatic one.
Today our compact shimmering color
and texture tomorrow may arrive today aware resisting finish away
tomorrow.
Maybe this instrument panel seems like
to use this finish for porch furniture from today's accomplishments come
tomorrow's idea.
There's news in aluminum finishes its inspiration for tomorrow from the datelines
of today.
The building.
Great Architect specified to achieve the effect is it
possible to make the architect color
and there's news in the answer cascading
castings of aluminum friction against muscles of tiny impression
creating a dark gray color mechanical to obtain the desired tone
and illustration of the possibilities which lie in mechanical finishing methods
variations of mechanical been issues can be used to produce dozens of different
tones and texture finishes in themselves or textures
and clusters for any overlying finish.
Perhaps the most common of all mechanical methods is buffing polishing polishing
with buffing Campomanes against a revolving wheel the smoothness
and brightness of the finish depend on the combination of buffing compound
and buffing wheel
or belt these finishes range from a high gloss to a soft satin finish
a wire brush provides a familiar scratch brush finish with its various affects the
texture of the surface depends on the finest
and stiffness of the wire in the brush.
Sandblasting is a fast
and inexpensive method of giving castings a clean uniform surface
variations in the kind and crossness of abrasive give finishes with texture
and shade.
The tumbling barrel is a practical method of removing birds
and other roughness from small parts.
Shops with a little soap
and water lubricant tumbled in the barrel results in a smooth burnished surface on
the product hundreds of which can be finished in the same economical operation.
After one or more tumbling.
The product is finished and ready for market mechanical finishes scene
and many architectural details spandrels windows doors
mail boxes railings grills these mechanical issues are
used to obtain the desired tone texture
and harmony in almost any American home are examples of several
mechanical finishes on aluminum where hand hammered trays the measure
utensils color buffed the many different mechanical finishes suggest more
combinations
and variations ideas for tomorrow from the processes we know today.
Truck drivers are rolling out the
barrel but with a been a shout all.
It wouldn't pay to spend much money for anything about the answer of chemical
treatment like the mechanical finishes this chemical treatment changes only the
appearance of the surface not its your ability.
It is an acid followed by water rinsing this chemical treatment prepares
and cleans the inside ready for the beer
and gives the outside an attractive silvery finish another widely used chemical
treatment is the caustic edge.
This produces a frosted finish on stamping forging some casting.
On name plates the words graduations
and designs can be engraved on aluminum by another chemical treatment
a chemical solution
that is the parts not protected by a stop off outlining the design on the surface
a great many products today.
Such as aircraft
or gasoline tanks are finished by one of the group of chemical treatments known as
the Al rock processes.
By chemical means
and oxide film is applied which is the core of the natural film
and gives greater protection in one of the our rock processes an alkaline chromate
solution is used to oxidize the surface a second chemical treatment seals the
oxide coating our rock coatings are used for both protective
and decorative purposes.
Base gasoline tanks are given an Al rock coating to protect them from the corrosive
effect of aviation fuel
and on outboard motors exposed parts get better protection because of the hour.
Rock process.
The finish on these motors takes a real beating subjected to spray vibration
and constant exposure.
The Al rock coating here serves a double purpose it bonds the paint to the metal
and adds to the protection afforded by the paint rivets are often given a
protective coating the AL rock processes as well as the other chemical treatments
provide economical methods of finishing either for protection
or appearance methods in use today which will provide material for tomorrow.
To be the contents of factor today with the modern miracle drug selling
is protected by aluminum
and aluminum aluminum with an aluminum
organic they break the virtues of
aluminum not only in protecting the content but.
Outstanding developments in organic finishes on aluminum have been made in the
packaging field aluminum foil
and collapsible tubes are attractively decorated by anomaly printing
and lacquer ink. Here is I appeal sales appeal.
Aluminum takes and holds paint well
but surface preparation is important for many articles of thorough cleaning with a
grease solvent is sufficient.
Or hard
or usage a chemical treatment may be used for instance the element in tank of this
truck was sprayed.
With a dilute solution of phosphoric acid rinsed
and dried zinc chromate primer was applied followed by top coats of an animal.
So today organic finishes are applied to aluminum
or any of its allies another development which holds promise for tomorrow.
Sailing zero the ground is completely obscured while somewhere up there airliner
way home aboard passengers are under the pilot
the airplane safely home with the help of new types of electronic operators.
The tiny electrical impulses of these devices need an excellent conductor today
lightweight aluminum is being you aluminum plated with silver to provide the bow
electrical resistance needed in the contact electro plating up alone
and has arrived.
Yeah Solomon
and can be successfully electroplated the secret is in the surface preparation
special treatment is required for aluminum in one method of operation the aluminum
surface is first thoroughly cleaned it is next.
Rinse
and then immersed in of sodium zinc a solution after this comes another rinsing
then it is ready for plating in solutions
and with techniques much the same as those used for other metals primarily
electric blades on aluminum are used for appearance
and resistance to wear plated aluminum is successfully answering many problems as
in this fabricated handle it is opening new fields.
But tomorrow from the findings of today
with the Pacific Fleet Navy planes by rushing water resistant corrosion during long
months of service in the second world war.
Taking off on countless patrol and bombing missions.
Amid salt spray like dropping saw in the frozen lot these planes through the gap
by special Navy are very critical parts of every plane were given a penny for added
protection
and the baseball paying the noted treatment forms a hard protective oxide coating
on the surface of the of the minim by an electro chemical process.
Earlier we saw
that the al rock treatment made such a coating by chemical means the electro
chemical treatment makes a better and stronger coating most practical
and durable of the unordered finishes is that known as the OH MY LIFE finish.
Let's see just how hard it is.
Half of this test these is I'm finished the other half has been treated by the olam
alive process a rotating wheel of the brakes two turns equally on both halves.
After three thousand revolutions the abrasive wheel has left the worn track on the
unfinished half while the ally fortune show is hardly anywhere.
Thanks to its hard thick oxide coating.
Typical operations in the production of a little light finishes.
Include a cleaning bath followed by a rinse in water.
Next the articles are another CLI oxidized in acid electrolyte for a period from
ten to thirty minutes. The final step is the ceiling of the finish.
So that it won't absorb stains
and for increased resistance to corrosion big installations of a quip meant for
applying a light finish are in use by many industries.
This is a production line operation in the finish of aluminum furniture all over
America products of aluminum with all my life finish are existing where furniture
and accessories finished by the aluminum I process are attractive
and durable yet as here at last is a metal that's easy to clean.
Even those sticky remains come off with ease because of the hardness of the
Aluminite finish in the production of a light finish.
We have seen that at one stage.
It had to be sealed to keep it from staining this some sort of characteristic can
be an advantage if before sealing the coating is dipped in a dye solution.
It takes on color just as cloth is dyed the dye actually becomes part of the
coating in this example a resist was he was on the areas which were not to be
colored these colored aluminum nameplates illustrate a practical use of the a
little I process a little I finish in colors offer as many possibilities in terms
of beauty
and in terms of practical use for instance colored fittings on airplane hydraulic
lines for quick identification nameplates
and easy to read dials
that died a little light finishes are best for interior uses
when brilliant colors are wanted Alz that reflectors are produced by another
and noted treatment closely allied to the element like process eighty five percent
reflective efficiency.
Can be obtained by an electrolytic treatment the surface is protected by a
transparent and no
that coating a regular cleaning will keep the Alz Ach finish bright the oxide
film of the a little I finished Similarly will retain its beauty with only an
occasional wiping your ice cube trays illustrate a combination of conditions they
are first given a frosted surface by caustic dip then finished by the little I
process and this permanent license plate is a combination of enamel
and the light finish is a striking example of the beauty of the Allied finish.
Is this escalator housing the pleasing tones
and textures were produced by a combination of mechanical
and a light finish its many variations of tone
and texture are possible through the use of mechanical
or chemical methods followed by a light finish accomplishments of today
ideas for tomorrow.
Dateline tomorrow.
From today's finish that spans the weather tomorrow with mom and garden vanishes.
Today the satin finish of a tea set tomorrow all the impressive lobby of the
building today silver plated aluminum radio equipment
plated aluminum hardware today.
Aluminum foil to protect cigarette tomorrow
and evening wrap bubble omentum cloth aluminum finishes
that make it more beautiful
and more useful than he has for protection money has bought decorations.
From the accomplishments of the day will come your problem.
Your uses news for the datelines. Tomorrow.
God.
