ABOUT US

FEEDING THE KEY COMPONENTS TO THE ELECTRIC POWER SECTOR FOR FORTY YEARS.

We are a leading supplier of the Amorphous alloy metal ribbon a key component of the distribution transformers. Amorphous ribbon is a cutting-edge alloy metal ribbon 0.03mm thick, energy saving low core loss material. Amorphous alloy ribbon is already being used to replace the conventional CRGO Electrical Steel sheet that has been in use for over 100 years in distribution and power transformers, which are highly inefficient and incur substantial energy loses. Currently all major manufacturers of transformers in USA, EU, China and India have switched over to Amorphous ribbon in their transformers. India alone is importing over 50,000 MT/annum Amorphous ribbon.

Our association with power sector goes back over 40 years, as a trading company we have been supplying Cold Rolled Grain Oriented (CRGO) Electrical Steel to transformer manufacturers in many countries including South-East Asian, India, and in South America. We work closely with ThyssenKrupp Electrical Steel Mills in Germany and France as well as with Nippon Steel in Japan.

We have extensive in-house technical knowledge about CRGO Electrical Steel following its technological development at close hand over the past 40 years. As one of the leading supplier of CRGO Electrical Steel worldwide we offer complete range of high-quality CRGO Steel sheet in High Permeability grades with low core losses.

European Union countries, United States, and other major industrial nations are committed to replacing the use of – Cold Rolled Grain Oriented Electrical Steel Sheet in Power and Distribution transformers with energy efficient Amorphous ribbon – these nations are committed to phase out use of CRGO Electrical Sheet by 2027, under the United Nations Convention on Climate Change Protocol signed by industrialised nations and rest of the world – help to reduce global warming. Prevailing use of CRGO Electrical sheet in transformers is a major contributor to global warming due to its very high loses dissipated in the form of heat generated.

AMORPHOUS METAL

Power industry today is searching for technology that saves energy and reduces operating costs by minimising core loss in the transmission and distribution of electrical energy.

In despite of our historical close association spanning over 40 years with CRGO Electrical Steel, we are always ready to embrace new technologies which can help to distribute the electric power more efficiently.

Our partners have developed a new material called Amorphous Metal Alloy which is used to make transformer core instead of using traditional CRGO Electrical Steel / Silicon Steel laminations.

Amorphous alloy is type of advance magnetic material containing Iron, Silicon, Boron, and other elements.

The production of Amorphous ribbon requires rapid solidification from molten state.

The molten state alloy is cooled from 1600 centigrade to below 200 C at the rapid speed of 1 million C/second. Amorphous alloy ribbon is 30 microns thick (0.03mm)
