Description

Alloy 52K13 °F used: for the production of small permanent magnets.

Note

Alloy with magnetic energy (16−24)·103 TA/m.
Depending on the content of vanadium and the temperature property can be obtained the desired ratio of the coercive force and residual induction in the range (4,8−32)·103 A/m and 1.2 to 0.65 T. the Alloy becomes magnetic properties Locle cold deformation of 70−90% and subsequent tempering.
Alloy anisotropic. Wire of alloy grade 52K13 °F after a special thermomechanical treatment has a coercive force (32−40)·103 A/m at induction 0,80- 1,0 T.
