Product Description

1J46 Soft Magnetic Alloy Precision Alloy Wire/Strip/Bar Iron-nickel Alloy

OhmAlloy-1J46  (Soft magnetic alloy)
(Common Name: Ni46, E11e, 46H, 45-permalloy, PB)

Ohmalloy-1J46 is a nickel-iron magnetic alloy, with about 46% nickel and iron content. It is derived in accordance with permalloy. It has characteristics of high permeability and high saturation magnetic flux density.
Alloy melting in a vacuum medium, cast into ingots, after hot forging blanks made of sheet metal, and then after hot rolling, pickling, surface treatment, cold rolling into finished products.
