Cogent thin gauge products significantly reduces losses at higher frequencies compared to normal gauge electrical steels.  Opening a whole new array of design and application possibilities for your business.

The product range also includes the thin gauge grades, which offer the superior performance required for high frequency applications, and HP-grades for applications where improved permeability is of importance. Another recent addition to our product portfolio are  our grades with guaranteed mechanical strength.

Total Cost of Ownership drivers:

• Light weighting: Same performance with less steel

• Space: Same performance with less space

• Assistance: Engineering data & assistance for durability-design available

Key Application Areas:

• Automotive (H) EV vehicles

• Aviation

• Power  tools

• Household appliances (Vacuum cleaners)

• Transformers

• Filters

• Industrial high speed motors

• Magnetic bearings

• High speed pumps and compressors

Cogent offer the widest range of thin gauge electrical steels in the market. These thin materials give lower losses at higher magnetisation frequencies and in Hybrid Electric Vehicles this offers the same efficiency and torque with a smaller and lighter weight motor.

As these products are typically used  at higher rotational speeds please find a below an overview of guaranteed and typical losses also at higher frequencies (400 &2500)
