ND2149 Nickel Iron Alloy 4750 Bar

Descriptions of Nickel Iron Alloy 4750 Bar

Alloy 4750 is a nickel-iron alloy that combines a high saturation flux density with high magnetic permeability and low core loss. It is a protecting amalgam with high beginning penetrability. It is a flexible material that can be used in different applications like laminated cores for instrument transformers, magnetic shields, and cores for certain electronic and communications devices where its high permeability at low magnetizing forces can greatly increase the device’s efficiency.
