G-IRON H.I.F. (High Intensity Field)

G-iron H.I.F. is a high-permeability soft magnetic material with a high permeability and high saturation level (Bs=2,12 Wb/sq.m) able to shield magnetic fields from 0 to 1.000 Hz. This material is made of 99,85% (minimum) pure iron (Fe). Other elements in the alloy, combined with a particular production process, give G-iron H.I.F. the following characteristics:
   
    •    Not subject to aging
    •    Isotropic
    •    Narrow hysteresis cycle
    •    Magnetic properties are not affected by severe mechanical deformation

G-Iron H.I.F. is particularly indicated when the shield is very close to the source of a high intensity magnetic field and when the magnetic field is generated along multiple directions. In some cases it is convenient to use a combination of the two materials.

G-IRON L.I.F. (Low Intensity Field)
G-iron L.I.F. is a high-permeability magnetic alloy with a high saturation level (Bs=2,0 Wb/sq.m) able to shield magnetic fields from 0 to 1.000 Hz. This material is made of 97% iron (Fe). Other elements in the alloy, combined with a particular production process, give G-iron L.I.F. the following characteristics:

    •    Not subject to aging
    •    Non Isotropic
    •    Narrow hysteresis cycle
    •    Magnetic properties are not affected by small mechanical deformation

G-Iron L.I.F. is ideal for magnetic shielding when the magnetic field with has a low level (lower then 10 μT) and when the shield covers a large area. In some cases it is convenient to use a combination of the two materials.

Technical Characteristics L.I.F
Shielding mode: absorption
Initial permeability: 500
Relative permeability: 7000
Saturation induction: 2,0 T
Curie Temp.: 740 °C (1364 °F)
Attenuation @ 50 Hz 100 μT*: 14 dB (80%)
with shield completely closed
Attenuation @ 50 Hz 100 μT: 26 dB ( 95%)
with low reluctance magnetic shunt

Loss due to mechanical deformation**: 2 dB (21%)
