Magnetic Properties

DI-MAX HF-10X offers best in class performance at thicknesses of 0.25 mm. 


  • Lowest core loss offered
  • Aid increasing motor efficiency
  • High yield and tensile strength


Release grading is based on as-sheared Epstein test and core loss at 1.0 T and 400 Hz in accordance with ASTM A343 (reference data at frequencies above 400 Hz were developed in conformance with ASTM A348). Representative properties using stress relief annealing are shown for reference. 

Magnetic Induction at 2500 A/m (B25): 1.56 T Magnetic Induction at 5000 A/m (B50): 1.66T Volume Resistivity:   59 μΩ•cm Saturation Induction: 1.97 

Insulative Coating

DI-MAX HF-10X is available in three insulative coatings: C-5 phosphate, CARLITE®, ANTI-STICK™, and C-5-R.
