Balco Aluminium from Korba, Explained for Buyers

Bharat Aluminium Company Limited was set up in 1965 as a Government of India undertaking. Its main operations are in the town of Korba in Chhattisgarh, a coal-rich district, which matters because aluminium smelting is extremely power hungry and BALCO runs its own captive power plant.

In 2001 the Government divested 51% of the equity to Sterlite Industries (India) Limited, the company now known as Vedanta Limited. The remaining 49% is still held by the Government of India. In the market, Balco is therefore described as a Vedanta group company.

BALCO's own description of its finishing lines lists ingots, wire rods, busbars and rolled products, and it also casts billets for extrusion. The smelter uses prebake technology. A second smelter was added at Korba in 2004.

For a Bangalore buyer, that product mix means Balco metal turns up in two ways. Directly, as rolled sheet and coil or as electrical sections. Indirectly, as billet that an extruder turns into pipes and profiles, or as primary ingot that a secondary smelter remelts and alloys.

Wire rod deserves a separate mention. It is the starting stock for drawn aluminium wire, and wire is one of the forms on our product sheet. If you are buying wire for winding, earthing or binding, tell us the end use, because conductor work and general-purpose wire are drawn from different alloys and tempers.

Electrical contractors and panel builders are the most frequent users. Aluminium carries roughly 60 percent of the conductivity of copper by volume, but at about a third of the weight, which is why it is used for overhead conductors, cable cores and busbars. Our electrical and power distribution page covers the wider metals list for that sector.

Fabricators use Balco sheet in the same way they use any other Indian mill sheet: enclosures, ducting, cladding, trays and covers. What matters for them is the alloy and temper, and those are covered on the aluminium coils, sheets and plates page.

For most shop-floor work, no. A 1.5 mm sheet in 5052-H32 is defined by its alloy limits and its tempered strength, and both mills roll to recognised standards. The difference shows up in paperwork and approvals. Government, PSU and large EPC tenders sometimes name approved mills, and a project that has standardised on one source may not accept the other without a deviation request.

If your enquiry is open on brand, say so. We will quote whichever certified Indian source suits the size and temper. If it is not open, name the mill and we will confirm before quoting. The table below summarises the two producers on our product sheet; for more on the other mill, see Hindalco aluminium.

Ask for three things in writing: the alloy designation, the temper, and the certificate type. Jubilant Impex supplies material with a test certificate from a Government-recognised test house, and passes on the mill certificate where one is available for the lot. Check that the coil or bundle number on the material matches the certificate before the material goes to the shop floor.
