 +Alphaform LF has similar magnetic properties to such materials like [[Fluxtrol]], but it is delivered in a formable state so that it can be modelled into a desired shape. A [[flux concentrator]] made from Alphaform LF can be easily retrofitted to an existing induction coils. Manual shaping of such flux concentrator might result with wider mechanical tolerances than it is the case for machined parts.[(datasheet>[[http://fluxtrol.com/inc/pdf/AlphaForm-LF-Specs.pdf|Alphaform LF, data sheet {accessed 2015-09-21}]])]
 +
 +The product is a [[soft magnetic composite]] based on thermal-curing epoxy binder. The [[resin]] cures by exposing to temperature up to 190°. After curing and during normal operation the part can be exposed to 225° for prolonged periods, and up to 300° for short intervals.
 +
 +The "LF" stands for "low frequency" as compared to frequency ranges of other Fluxtrol materials.
