1C003
a. Initial relative permeability of 120,000 or more and a thickness of 0.05 mm or less;
Technical Note
For the purposes of 1.C.3.a., measurement of initial relative permeability must be performed on fully annealed materials.
b. Magnetostrictive alloys having any of the following:
1. A saturation magnetostriction of more than 5 x 10⁻⁴; or
2. A magnetomechanical coupling factor (k) of more than 0.8; or
c. Amorphous or 'nanocrystalline' alloy strips, having all of the following:
1. A composition having a minimum of 75% by weight of iron, cobalt or nickel;
2. A saturation magnetic induction (Bs) of 1.6 T or more; and
3. Any of the following:
a. A strip thickness of 0.02 mm or less; or
b. An electrical resistivity of 2 x 10⁻⁴ ohm cm or more.
Technical Note
For the purposes of 1.C.3.c., 'nanocrystalline' materials are those materials having a crystal grain size of 50 nm or less, as determined by X-ray diffraction.
