Soft Ferrite is a ferromagnetic oxide with Fe2O3 as the main component, which is produced by powder metallurgy method. There are Mn-Zn, Cu-Zn, Ni-Zn, etc. Among them, the output and consumption of Mn-Zn Ferrite is the largest, and the resistivity of Mn-Zn Ferrite is low, ranging from 1 ~ 10 ohm/m, which is generally used at frequencies below 100kHZ. Cu-Zn and Ni-Zn Ferrites have a resistivity of 102 ~ 104 ohm/m and a low loss in the radio frequency range of 100KHz ~ 10 MHZ. They are commonly used in radio antenna coils and radio intermediate frequency transformers.

Product Description
On-line pyrolytic reflective coated glass is produced using CVD technology (chemical vapor deposition) that creates a perfectly uniform layer of metal oxide chemically bonded to the surface of the glass. As this hard chemical layer fully bonds to the glass, the glass can be cut, bent, drilled, tempered, heat strengthened and laminated without affecting the coating.
