alfenol

[′al·fə‚nōl]
(metallurgy)
A permeability alloy that has 16% aluminum and 84% iron; it is brittle and at 572°F (300°C) can be rolled into thin sheets; used for transformer cores and tape recorder heads.

Alfenol

 

a soft magnetic alloy consisting of 16 percent aluminum and 84 percent iron. Alfenol is characterized by high magnetic permeability in weak fields (initial magnetic permeability to 3.61 megahenries [MH] per m; maximum to 145 MH/m [1 MH/m ≈ 796 gauss/oersted]).

There are several materials used to fabricate the cantilever, such as elastic material (polymers), piezoelectric material (PZT-5 and PVDF), and magnetostrictive material (Galfenol and Alfenol) [10-14].

Several magnetostrictive materials, such as galfenol and alfenol (Fe-Al alloy) [15, 16], can be used as raw materials of the whisker beam.
The magnetostrictive coefficient of galfenol is higher than that of alfenol (their saturation magnetostrictions are 250 and 120 ppm, respectively, reported in [19]).
