Hi-lite details.

Hi-Lite goes way beyond the mere supply of ultra-thin electrical steel with maximum magnetic permeability and minimum power loss – it represents a whole new collaborative approach to the development of pioneer applications for low-hysteresis laminated silicon-steel sheets. Sura Hi-Lite is the widest range of grades in the market. More grades available on demand.

Magnetic losses

Designers of high frequency motors and generators will see a significant reduction of magnetic losses when Hi-Lite grades are used instead of good standard gauge electrical steels.

 

Producers of inductors operating with fluxes containing noise or harmonics at low inductions but very high frequencies can significantly reduce losses by using Hi-Lite.

 

Space and Weight

Individually optimised 80 kW internal permament magnet motors with the same efficiency using different steel grades. Demonstrating that space and weight can be saved by designing for higher speeds using thin gauge Hi-Lite grades.

Coatings

Hi-Lite grades are normally supplied with a thin Suralac 7000 coating or with a Suralac 9000 bonding coating. Suralac 7000 is a C-5 type inorganic coating which provides good insulation resistance, very good temperature capability and a high stacking factor. Suralac 9000 is used to bond laminations, applying temperature and pressure, into a core with good mechanical strength and improved magnetic properties. Uncoated material or other Suralac coatings are also applicable to Hi-Lite grades depending on customer requirements.

Delivery options

How would you prefer to have your Hi-Lite delivered? We can slit it in anything from 12 mm to a full coil of 1150 mm width or cut it into pieces from 3500 x 1150 mm down to 12 x 12 mm. We do not only supply steel and provide data on the material. We can also assist you in finding you the best supplier of laser cut laminations for prototypes, supply you with stamped laminations or finished cores using a sub-supplier. From single elements to the design, manufacture and supply of complete components, the choice is yours.
