Assam Carbon Products Limited manufactures electrical, mechanical and specialty carbon products at Guwahati, Assam and Patancheru near Hyderabad. The 2024-25 annual report says the Guwahati unit produces carbon and graphitised blocks and blanks used in electrical-carbon applications, including carbon-brush fabrication for railways, steel, sugar and paper mills, motors, generators, mining and power utilities. At Patancheru, the company fabricates and precision-machines finished components. The electrical-carbon division makes precision-machined carbon brushes, railway traction components, pantographs, current collectors, silver-impregnated graphite and railway-signalling contacts. Its mechanical-carbon division makes engineered seals, bearings, vanes and thrust pads. The specialty-graphite division serves diamond tools, optical-fibre manufacturing, hard-metal sintering and electronics. The company also makes graphite-based and carbonized products such as high-temperature insulators, fuel-cell components, heating elements, casting dies, lubrication blocks and custom-engineered graphite parts. The source identifies railways, power, steel, automotive and electronics as served sectors.
About this company
Assam Carbon Products Limited is one of India's oldest and most established manufacturers of carbon, graphite and allied engineered products. Incorporated in 1963 with its roots in Guwahati, Assam, the company began as a maker of carbon brushes and has since grown into a broad-based supplier of electrical carbons, mechanical carbons and specialty graphite components used across heavy industry. Its product portfolio spans carbon brushes, current collectors, metallised carbon strips for railway pantographs, signalling contacts, carbon seals, bearings, gland rings, steam joints, thrust pads, radial bearings and carbon vanes. These components serve demanding end markets including railway traction, power generation, steel, cement, sugar, mining, petrochemicals and general chemical process industries, where they perform in high-wear, high-temperature and electrically intensive applications. A defining chapter in the company's history is its long association with Morgan Advanced Materials plc, the global carbon and ceramics group, with which it operated as a subsidiary and joint-venture partner for several decades. When Morgan chose to step back from the carbon business in India, the present management acquired Morgan's shareholding around 2016, returning the company to independent Indian ownership while retaining perpetual rights to the product grades and technologies it had adopted from that relationship. This technical heritage continues to underpin its manufacturing know-how. The company runs manufacturing operations in Guwahati, Assam and at Patancheru in Telangana, supported by a workforce of roughly 350 people, and serves a customer base that includes large industrial and infrastructure users. Drawing on more than six decades of operating history, it is positioned as a specialist supplier in a niche segment with relatively few domestic players. In the unlisted market, Assam Carbon Products draws interest as a long-established, profit-oriented engineering company with a recognisable industrial pedigree and a former multinational parentage. Its shares are held in dematerialised form through NSDL and CDSL and carry a face value of ₹10. Indicative market data reflects transactions among private buyers and sellers, as the stock is not traded on any public exchange.
