1J46 46Ni-Fe Soft Magnetic Alloy Equivalent to 45-permalloy
Transformer Grade PERMENORM 5000 H2 exhibits a very coarse-grained, anisotropic structure after final heat treatment. The cold rolled material can show a cubic texture which results in high permeability values in the rolling direction and to some extent in transverse direction after the final annealing.
PERMENORM 5000 exhibits the highest saturation polarization of 1.55 T in the NiFe system in combination with a high initial and maximum permeability.
PERMENORM 5000 H2(1J46) is available as solid material (bar, rod, wire) or as cold rolled strip in thicknesses from 0.025 mm to 2.0 mm. PERMENORM 5000 V5 is available as cold rolled strip in thicknesses from 0.05 mm to 2.0 mm.
For optimum magnetic properties PERMENORM 5000 should be annealed in an oxygen-free, dry hydrogen atmosphere with a dew point below -40°C, at a temperature above 1000°C. Recommended parameters for stationary annealing are 5 h 1150°C.
