• 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


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

AlphaForm comes in a container about 5.5” X 5.0” X 3/8” andis easy to work with.


How to Attach AlphaForm Hand MoldableInduction 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 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


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

• 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.
