The curious will ask “What is an iron-chromium aluminium alloy?”

Fe-chrome aluminium alloy is a functional material for electrical heat conversion.

Prior to this, China's 1300 ℃ temperature above the use of high-performance electric heating alloy materials in semiconductor manufacturing, photovoltaic, high-end glass kilns, ceramic sintering, exhaust gas treatment and other fields can not be self-sufficient. The problem profoundly affected the international competition pattern of related industries.

The core technology content of this project lies in the independent research and development of a new high-performance iron-chromium aluminium alloy material and its manufacturing technology that can be used stably under the ultra-high temperature condition of 1400℃, breaking through the "neck" technology. 

 This scientific and technological achievement is mainly used in photovoltaic power generation, energy storage, urban clean heating, etc., which is more in line with the direction of the national "carbon peak, carbon neutral" policy, and can effectively promote energy saving and carbon reduction, and solve the problems of similar imported electric heating materials such as necking, expensive and untimely supply. In the past five years, the new materials developed by the project have performed well in the domestic and international electric heating alloy market, with sales of 242 million yuan and profits accounting for more than 60% of GITANE 's total profits.

The project results in the development of new materials by virtue of high temperature, high performance characteristics, ceramic sintering, glass manufacturing, non-ferrous metal smelting, such as the original coal, natural gas combustion heating, and gradually shift to a more controlled temperature, lower safety risks, no environmental pollution in the form of electric heating heating. Yang Qingsong, director of the technical development department of GITANE New Material Company, introduced that under the goal of "carbon peaking", the installed capacity of photovoltaic power generation has increased significantly, and the demand for photovoltaic cells has grown significantly, and in order to improve the photoelectric conversion efficiency, silicon wafers have shifted from polycrystalline to monocrystalline, which has put forward higher requirements for silicon single crystal manufacturing and diffusion heat treatment equipment for semiconductor doping. As a result, the materials achieved by the project were successfully applied to single crystal manufacturing and diffusion heat treatment furnaces, and industrialisation was achieved by seizing the opportunity of the increase in the installed capacity of photovoltaic power generation, and the benefits of the project grew faster. Effectively break the monopoly of foreign technology, get rid of the dilemma of relying on foreign materials for high performance electric heating materials required in the fields of chip manufacturing, coal to electricity, gas to electricity, etc. GITANE New Material Company has run out of the "acceleration" of innovation and development.

In terms of the transformation and application of the project results,  GITANE has become the exclusive supplier of such products to a number of well-known downstream semiconductor equipment manufacturing enterprises with the project results, and the project results materials have successfully replaced imported materials. What's more, the new material developed by the project of "Technology Development and Industrialization of High Performance Iron-Chromium Aluminum Alloy" has also become the designated product for leading domestic and foreign burner enterprises.

The reporter learned that the world's only two downstream manufacturing enterprises with a complete set of technology from "high temperature oxidation-resistant metal fibres" to "metal fibre burners" have designated Gitane's new materials for the project as "the only available domestic material". The material is also used in the electric heating element of the glass furnace of Fuyao Group (Fujian) Machinery Manufacturing Co.

 It is reported that, with the gradual expansion and occupation of the high-end market share of the project results of "High-performance iron-chromium-aluminum alloy technology development and industrialization" of GITANE New Material Company, the company's products have replaced foreign imported materials in the field of high-end demand for domestic electric heating alloys, taking the leading position in the peer group and being widely recognized by domestic and foreign customers.
