Cogent Power, a Tata Steel Enterprise, offers a comprehensive range of electrical steel grades and services for manufacturers and designers of low carbon vehicles which includes our Hi-Lite products, the ultimate non oriented ultra-thin gauge electrical steels for high frequency applications.
Hi-Lite is a series of ultra thin non-oriented electrical steels that opens up a new world of possibilities when designing high frequency applications. It helps you achieve harmony between size, weight, energy efficiency and performance
Our ultra-thin-gauge electrical steel laminations already handle the highest rotational speeds recorded. Specified for the greenest hybrid vehicles, the most advanced vacuum cleaners and the fastest cars in the F1 circus, Hi-Lite puts a new spin on innovation
For application frequencies beyond the standard 50 or 60 Hz, thinner steel may be needed to maintain low losses. The Hi-Lite range, available with a Suralac®7000 insulating coating, and now also with the Suralac®9000 bonding coating, has been optimized for medium to high fundamental frequencies (200 -2500 Hz) and harmonics up to about 25 kHz. For the most extreme applications, we have developed Hi-Lite NO 10, the thinnest wide strip electrical steel on the market.
The special qualities of the Hi-Lite range are particularly relevant to today’s automotive industry. Global interest in electric vehicles (EVs) and hybrid electric vehicles (HEVs) is growing dramatically: the key technological enablers for these applications are electric machines (motors), along with their drive systems. Design optimization of electric motors for automotive applications has become an urgent priority.
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.
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.
We are also able to offer the standard electrical steel range for high efficiency motors.

Electrical steels play a vital role in the generation, transmission, distribution and use of electrical power. They are one of the most important magnetic materials produced today. We supply a wide range of processed grain-oriented and non-oriented electrical steels for use in a range of applications:
- motors within the energy transmission and transport networks
- automotive powertrains
- industrial machines
- household appliances
Our quality-assured electrical steels deliver:
- consistent magnetic performance
- excellent delivery performance
We also offer new coatings that combine performance with environmental and safety benefits.
We have extensive in-house knowledge and experience of electrical steels and their applications – including many years of first-hand experience in downstream processing within the group
Our product range also includes:
- Hi-Lite ultra-thin gauge grades - offering the superior performance required for high-frequency applications
- HP-grades for applications where improved permeability is of importance
A recent addition to our product portfolio are grades with guaranteed mechanical strength.
New coatings combine performance with environmental benefits
At Cogent we believe that an environmentally responsible company is a successful company. We ensure that our materials are produced in a safe and environmentally-friendly environment. This duty of care is carried forward into our products and their application. That’s why we offer:
Chrome-free phosphate insulation coating. This coating is applied to our entire grain-oriented product range. It eliminates the risks from hexavalent chrome and delivers a superior insulation coating which is safe and environmentally friendly.
Suralac 7000FF. A formaldehyde-free, organic coating. This ensures a clean working environment in application, free from potentially hazardous fumes.
Our new bonded coating, Suralac 9000, is now available for our thin gauge products. This coating may be heated to enable lamination stacks to bond together. This type of bonding delivers improved noise performance for large volume production of thin materials. It is compatible with other traditional insulation coatings.
