Ferrite cores are prepared from a combination of various Ferrite materials to concentrate the energy of the HF Generator into the welding area. Ferrite impeder cores are used for concentration of magnetic flux in high frequency, RF, induction welding of steel tube and pipes. In this application ferrite core experiences temperature upto 150oC and the core properties must be optimized for this environment. For these applications, special ferrite materials are offered.
They are having following excellent physical properties.
