is a space-age process that according to
its users, "significantly" extends the productive life of
materials, such as ferrous and non-ferrous metals, metallic alloys,
carbides, plastics (including Nylon on Teflon) and ceramics. The most
obvious is for steel and alloys of steel.
The process also works on aluminum
and bronze casting-which have built-in stress due to the shrinkage of molten
metal after it cools in the molds. With a change in density-dimensional
stabilization and increased lubricity and parts stabilization by the COLDfire
Process. It returns the metal to its original state, bonds
it, making it more durable for tighter tolerance of machining.
The COLDfire Process works by improving the physical and mechanical properties
of various materials - actually transforming chemical microstructure into a
new, more refined, uniform substructure that transfers a new
"kind" of toughness into the material. The material is cooled to minus
350 degrees F (- 215 degrees C) and heated to + 350 degrees F (+ 180
degrees C). The process is performed to a
precise, computer controlled time table in 12 to 24 hours.
The process works on
crank-shafts, camshafts, cylinder heads, connecting rods, push rods, rocker
arms, blower, turbo parts, valves, valves springs, pistons, rings, pins,
ring/pinion, axles, drive lines, u-joints, brake parts, steering parts and
entire engine. This should increase your horse-power and RPM by 6%
or more. Do not forget the spark-plugs (works great).

Coldfire's Cryogenic Thermal Cycling Process gives you better performance
and more than doubles the life of your rotors.... Guaranteed!
Three times the life
Decreases Vibration and microcracking by 30%
The most Technically Advanced Rotors
available. These Rotors undergo a special deep Cryogenic Thermal Cycling
Process. This process involves cycling the temperatures to extremes as low
as -320°F and to as high as 400°F. This process actually alters the
composition of the metal at the molecular level. Resulting in higher
resistance to heat warpage, cracking, greater brake co-efficiency and
longer Rotor life
Our tests have proven to extend the life
of your rotors and pads by 200% and increase performance by 20%. What does
this mean to you?.. Longer life, a reduction in maintenance and labor
costs as well as down time by at least 50%!
Race teams, weekend warriors and performance junkies
- We have had Awesome results with our Cryogenic Thermal Cycling Process
in motor sports applications. Significant performance gains have been
noticed in treated rotors. Rotor warpage and vibration has been greatly
reduced, Braking efficiency improves and leads to smoother more consistent
braking keeping rotors cooler.

pushes engine and drive train components to the absolute limits of their
durability. Extending those limits means more speed, better safety, and
more races won. For this
reason Cryogenic processing is becoming a necessary part of the
manufacturing process for racing components.
This racing experience will serve as an example to manufacturing
industries---now similarly engaged in there own competition against
manufacturing costs and waste, and the challenge to provide high quality
products with superior performance.
extremely low temperatures to make permanent changes in metal and plastic
components, cryogenic processing is not the typical –84 degrees C (-120
degrees F) cold treatment most heat treaters use.
It essentially involves exposing materials to temperatures below
–184 degrees C (-300 degrees F). If
done correctly, it creates a permanent change to the material that alters
many wear characteristics.
concept of changing metal through the use of low temperatures is
relatively new and not well understood.
Yet it is certain that exposure to very low temperatures does make
permanent changes in virtually all metals and to some plastics.
Observed changes include:
resistance to abrasion
resistance to fatigue

practice, cryogenic processing affects the entire mass of the part. It is
not a coating. This means
that parts can be machined after treatment without losing the benefit of
the process. Additionally,
cryogenics apply to metals in general, not just ferrous metals.
For many years, it was assumed the only change caused by extreme
cold was the transformation of retained austenite to martensite in steel
and iron. Because of this,
many misinformed engineers still believe that cryogenic processing is
"just a fix for bad heat treat".
It is now known that cryogenic processing has a definite affect on
copper, titanium, carbide, silver, brass, bronze, aluminum, both
austenitic and martensitic stainless steel, mild steel and others.
It is also known that plastics such as nylon and phenolics show
processing is currently in use in every form of racing imaginable. It is
used in virtually every class of NASCAR racing, IRL, CART, NHRA, IHRA,
SCCA, IMSA and ARCA, not to mention tractor pulls, go-karts, motorcycles,
boats, and even lawn mower racing. Controlled
Thermal Processing (CTP) has even done a fair number of axles for soap-
box derby cars. Over half of
the cars competing at any given NASCAR Winston Cup race run parts that are
cryogenically treated by CTP alone. Cryogenic
processing can have a positive affect on virtually every engine,
transmission, and drive line part, as well as many chassis parts.
there definite tests and data on racing and cryogenic processing that we
can point you to? Not yet.
Racers do most of their testing on the race- track or on the dynamometer.
These are not controlled experiments in the classical sense, and in
most cases they do not allow the results to be published because of the
risk of losing competitive advantages.
We do know that the use of cryogenic processing is on the upswing.
Its use by manufacturers of racing components has been growing
sharply. We also know that
very experienced racing experts have examined the effects of cryogenic
processing and have been very impressed.
the durability of components in the vehicles is the main reason for using
cryogenic processing. Racing
continually presents the engineer with the challenge of designing engine
and chassis components that will survive long enough to win a race, but
will not have any excess weight as a consequence.
Put in too much mass, and a car will be slow and handle poorly.
Make components too light, and they will not survive the race.
There is always this delicate balance: weight versus reliability.
The great thing about cryogenic processing is that it allows an
increase in durability without an increase in weight or major
modifications to component design. In
addition, the use of cryogenic processing has helped some racing teams
reduce costs, enabling some expensive parts to survive the stresses of
racing for use in subsequent races.
processing has become an integral part of the production process for many
racing components. Many top
racing teams have the process done if the manufacturer does not provide
it. They do so because
cryogenic processing has proven its worth time and again under extremely
competitive conditions. Racers
are generally people in a big hurry and would not take the time for
cryogenic processing if there was no advantage to it.
Applications that benefit from cryogenic treatment probably number
more than anyone expects.
of a racing car take a real beating.
It is not unusual for a racing vehicle to finish a race with the
brakes totally worn out. This
is especially true during road races and endurance racing, where brake
rotors can get so hot they glow visibly at night.
Cryogenic processing can be applied to both rotors and pads.
The net result is two to three times the life of untreated
components even under severe racing conditions.
As a side benefit, the rotors are less prone to crack or warp.
It is interesting that drivers report better braking action and
feel. Some drivers are so
sold on the concept that they have their street vehicles equipped with
are a form of brake, and the results are very similar.
Drag racers have been doing some work on clutch plates to measure
the coefficient of friction in highly instrumented cars.
They find that treated clutch facings will develop a higher
coefficient of friction but exhibit significantly less wear.
an offshoot of racing development, cryogenically treated rotors and pads
are making their way into fleet operations on the road.
The U.S. postal service specifies cryogenic processing for their
rotors and is experiencing up to three times as many miles as they were
getting on the unprocessed rotors. Similarly,
many police fleets are starting to adopt treating rotors and pads. They,
too, are experiencing large maintenance savings on both parts and labor.
What is metallurgically interesting is that the brakes are a gray
cast iron that has a pearlitic structure.
This rules out the austenite to martensite transformation as the
mechanism for increase life.
unexpectedly, chassis springs are also affected by cryogenic processing.
Chassis springs lose their spring constant during a race.
This can cause the chassis to lose its cornering ability, which
drastically slows the car. Loss
of spring constant also alters the height or road clearance of the
vehicle. The vehicle height
is critical at high speeds because it has a big affect on the aerodynamics
of the car, and hence on the handling and the top speed of the car.
advantage for cryogenic processing of springs is that the process seems to
eliminate or reduce harmonic vibrations.
If you have ever seen a high-speed movie of a valve spring at high
engine rpm, you will notice that the springs do not simply move up and
down. It does a very complex
hula dance because of the harmonic vibrations.
Racers typically have to design the spring and valve trains so that
harmonics do not interfere with the valve action.
processing of springs will usually triple the life before fatigue failure
occurs, and it will reduce the amount of spring constant lost from 20-30%
down to about 7%. This makes
it easier to set up the engine, as there is not such a wide variation in
the spring performance. It is
difficult to determine absolute spring life increases, because the racers
typically discard them long before they break.

we come across groups of springs that will not respond to cryogenics.
Analysis of these springs usually discloses large inclusions in the
wire, which become stress concentrators, causing failures at these
