The maximum saturated polarizability of the alloy with nickel content of (40-50) wt% can reach JS = 1.6 T, and it has medium permeability. By choosing suitable rolling and annealing conditions, the shape of magnetization curve can be changed in a wide range.

　　

　　This group of ferronickel alloys is a good choice when it comes to hard magnets that detect large currents or direct magnetic flux (such as torque sensors). These materials are characterized by saturated inductance of about 1.3 T to 1.5 T, coercivity of between 3.5 a/m and 10 a/m, and high permeability. By choosing suitable rolling and annealing conditions, the shape of magnetization curve can be changed in a wide range.
