Ferrite cores and impeders with the best properties for tube & pipe welding

Offering a top quality ferrite core to the pipe and tube industry is the number one focus of Kent Corporation.

Our proprietary blend of ingredients makes the ferrite last longer in your impeder!
Our ferrite cores are made from a specially formulated mixture of Manganese Carbonate, Zinc Oxide, Iron Oxide and Calcium Oxide. This proprietary mixture is then extruded in to the desired shapes and carefully packaged for immediate shipment.

Tesgo Tubey’s ‘definitions to know’:

Initial Permeability - A property of a material that describes the ease with which a magnetic flux is established in the component at very low magnetic field strength
Curie Temp -The temperature at which ferrite looses it’s permanent magnetism
Saturation Fulx Density - Saturation flux density is how much magnetic flux the ferrite core can handle before becoming saturated and not able to hold any more.
Resistivity - The measure of resistance to current flow in a material
