AlphaForm is a Fast and Easy to Apply,
Induction Magnetic Flux Concentrator
Fluxtrol’s AlphaForm high and
low frequency, soft, moldable
magnetic field concentrators
can be used with any copper
coil for quick, efficient results.


Fluxtrol’s AlphaForm is a Hand Moldable
Induction Heating Concentrator
• AlphaForm is a hand moldable concentrator
• AlphaForm can conform to tube style coils
• AlphaForm can be used with almost any induction coil geometry
• AlphaForm can be hand ground for a more precise shape
• AlphaForm can work with any induction frequency
• AlphaForm that is not used is not wasted and can be stored again
• AlphaForm is great for induction process development
• AlphaForm can give better heat pattern and control
• AlphaForm can reduce heat time and energy used by 20 – 50%


AlphaForm Moldable Induction Concentrator
AlphaForm comes in a container
about 5.5” X 5.0” X 3/8” and
is easy to work with.

Although AlphaForm has a long shelf
life, it will be even longer if it is kept
cool or even frozen until needed.


How to Attach AlphaForm Hand Moldable
Induction Flux Concentrator to Induction Heating Coils

Warm the AlphaForm to room
temperature and cut off the amount
needed. To more easily mold AlphaForm
place it in an oven or use a heat gun, not
to exceed 140 F as curing may begin.


Recommended Tools to Attach AlphaForm Hand
Moldable Induction Flux Concentrator to Induction Coils

We recommend using gasline Teflon tape and
heavy duty aluminum foil, 0.024 millimeters (0.9 mils)


AlphaForm Hand Moldable Induction Flux Concentrator

Place a piece of heavy duty aluminum foil along the
working edge of the coil. This will provide a flat surface to
form the AlphaForm against. Avoid using standard
aluminum foil as it may be difficult to remove after curing.



Warm the AlphaForm to room temperature and cut or
tear off the amount needed.


Press the AlphaForm onto the desired areas of the
induction coil.


Place a heavy duty aluminum foil along the working edge of
the induction coil to create a flat surface to help shape the
AlphaForm.



Add layers of AlphaForm to the
induction coil as needed.



Unused AlphaForm can be returned to the
container, so there is no waste.


Wrap Teflon tape around
the AlphaForm to hold it
tight against the coil.
If not held in place,
AlphaForm may shift
slightly during curing.


To cure the AlphaForm, place
coil in an oven at 250 F (120 C)
for one hour. Then increase the
temperature to 375 F (190 C) for
an additional hour.



After curing, remove
the Teflon tape from
the AlphaForm.



After the Teflon
tape, remove all the
aluminum foil.



No machining is necessary, but you
can grind it to assist in creating
the shape you need.

AlphaForm has a
long shelf life, it will
be even longer if it is
kept cool or even
frozen until needed.

AlphaForm Hand Moldable Induction Flux
Concentrator for Tubing Coils Efficiency

Fluxtrol’s AlphaForm soft, moldable magnetic flux
concentrators can be used with any copper tubing for
quick improvements.

AlphaForm for Induction Process Development
• Apply AlphaForm to the induction coil
• Test your specific heating application
• If it yields good results, cure it in an
oven to permanently attach the
AlphaForm to the induction coil.

It can be added to improve a coil
and easily removed after testing.

AlphaForm, Doesn’t Need an Insulating
Material Between the Induction Coil Turns

Fluxtrol’s AlphaForm
is a soft, moldable
magnetic field
concentrator that
doesn’t need an
insulating material
between the coil
turns in most
applications.


AlphaForm is Perfect for Small Induction Tubing
A cut through a multi-turn 3/16”, I. D. induction tubing
coil reveals that Fluxtrol’s AlphaForm, bonds completely
with the coil without gaps or separation.
