Hindalco Industries Limited

Aluminium is used extensively in the transport industry due to its high strength to weight ratio and its excellent impact absorption qualities. Western countries use an average of 140kg of aluminium per vehicle, whereas it stands at 40kg per vehicle in India.

Hindalco's high-quality aluminium is preferred for its superior alloy composition and metallurgical properties that meet stringent performance parameters. Our expertise is backed by the superior Wagstaff AirSlip casting technology. From brakes to ignition, transmission to suspension, cooling and exhaust systems to windows and structurals, ornamentals to accessories, automobile heat exchangers and registration plates, Hindalcoâ??s superior aluminium material is for making the most precise automobile components.

One of the largest integrated primary producer of aluminium in Asia. With a pan-Indian presence that encompasses the entire gamut of operations, from bauxite mining, alumina refining, aluminium smelting to downstream rolling, extrusions and recycling, Hindalco enjoys a leadership position in aluminium and downstream value-added products in India.

Our Indian aluminium operations are integrated and consist of bauxite mining, alumina refining, smelting and converting primary metal into value-added products. We have dedicated sources for critical raw materials such as bauxite, power and coal. We also have committed supply sources for auxiliary chemicals.

Our finished products include alumina, primary aluminium in the form of ingots, billets and wire rods, value-added products such as rolled products, extrusions and foils. Metallurgical alumina is used for our own captive needs. Chemical alumina and hydrates are used in range of industries including water treatment, fillers in cables and plastics, refractories and ceramics, glass among others.

Our facilities are in regions close to raw material sources, low cost and available labour and demand markets. This helps in reducing costs and improving profit margins. The technology upgrade has resulted in higher utilisation rates at our plants and improved efficiency.

We believe implementation of superior technology not only reduces costs but also provides superior and customised products, thus, improving our sales.

Hindalcoâ??s integrated complex at Renukoot, in Uttar Pradesh, India, houses an alumina refinery, an aluminium smelter and facilities for the production of semi-fabricated products. Power is sourced from our Renusagar power plant, located about 45km from Renukoot. Our facilities also include an aluminium smelter and an aluminium FRP facility (for rolled products, extrusions products and wire rods) at Hirakud (Odisha) with a captive power plant and coal mine, and alumina refinery at Muri (Jharkhand). Our Chemical grade alumina plant is located at Belagavi (Karnataka), and rolling mills at Belur (West Bengal), Taloja near Mumbai and Mouda near Nagpur (Maharashtra). Foil rolling facility is situated at Mouda near Nagpur (Maharashtra) and our extrusion plant at Alupuram (Kerala).

Hindalco's new age smelters at Aditya (Odisha) and Mahan (Madhya Pradesh), operating on state-of-the-art AP36 technology, have not only resulted in expansion of our capacities but also improved cost-efficiency of our operations. These smelters have their own captive power plants and source alumina from Utkal, our 100% subsidiary.

Utkal Alumina (Odisha) is a world class refinery with one of the lowest cost structure in the world. The bauxite for Utkal is sourced from Baphlimali mines by a 18 kilometer long conveyor, one of its kind in the world.

Everlast, a Hindalco brand, launched in December 2002, is made of aluminium and is ideal for all roofing and cladding needs. It is easy to use, durable and economical to work with. Using aluminium for roofing has many benefits. Some of them are the following:

Aluminium roofing sheets are extremely light and have a high strength-to-weight ratio.
Aluminium is an increasingly popular choice for use in installations and buildings. It is corrosion-resistant in almost any kind of environment. Even in highly corrosive industrial environments, it is resistant to fumes and vapours of organic compounds and to chemicals like ammonia, carbon dioxide and acids such as hydrochloric acid, nitric acid and sulphuric acid. Such corrosion resistance gives the metal a long life and keeps it looking good throughout its life.
The shine and brightness of aluminium livens its surroundings, and, because it doesn't stain, discolour or rot, it keeps its brightness and shine for a long time. Aluminium corrugated sheets can take a variety of finishes, colours and textures, which protect them and further enhance their appearance.
An aluminium structure can be easily dismantled, transported and re-assembled in a new location.
Though the metal is a good conductor of heat, its high reflectivity for radiant heat and light (75 to 80 per cent when new, 60 per cent after several years) keeps the interiors of aluminium building from five to eight degrees celsius cooler in summer, while its low emission rate cuts heat loss in winter.

It is easy to maintain and wash
