Alufluoride says smelter additions may need 30,900 tonnes

Alufluoride Limited says planned Indian aluminium-smelter additions could require 21,600 to 30,900 tonnes of aluminium fluoride annually, based on about 1.55 million tonnes per annum (MTPA) of new smelting capacity. The upper estimate exceeds Alufluoride’s 24,000 tonnes-per-annum (TPA) manufacturing capacity, expanded from 18,000 TPA.

How much aluminium fluoride demand could new Indian smelters create?

Alufluoride estimates that planned smelter additions could require 21,600 to 30,900 tonnes of aluminium fluoride a year. The company identifies NALCO, Hindalco and Vedanta as associated with about 1.55 MTPA of new smelting capacity, which it says equals 36% of India’s existing aluminium-smelting base.

The range is derived from Alufluoride’s stated consumption assumption of 14 to 20 kilograms of aluminium fluoride for each tonne of aluminium produced. At 14 kilograms per tonne, 1.55 MTPA of new output implies 21,600 tonnes of annual demand; at 20 kilograms, it implies 30,900 tonnes. Aluminium fluoride, also called AlF₃, acts as a flux in the electrolytic reduction of alumina at primary aluminium smelters.

The prospective demand is not scheduled to arrive at one time. Alufluoride says Vedanta’s additions are expected by FY28, while NALCO’s Angul smelter is indicated for 2030-31. The presentation does not provide individual project capacities, purchase agreements or an expected share of supply for Alufluoride.

How does potential demand compare with Alufluoride capacity?

The estimated 21,600-to-30,900-tonne demand range equals 90% to 129% of Alufluoride’s current 24,000 TPA capacity. The company’s manufacturing scale is also described as 80 tonnes per day, after capacity increased from 18,000 TPA.

At the upper end, the prospective requirement is 6,900 tonnes above Alufluoride’s existing annual capacity; at the lower end, it is 2,400 tonnes below it. The presentation does not disclose current capacity utilisation, production volume or uncommitted capacity, so the comparison measures the possible market pool rather than potential company sales.

Alufluoride’s revenue is concentrated in the same product. Aluminium fluoride generated all Rs 63.9 crore of Q2FY27 revenue, up 17% year on year, while its 4.1-megawatt captive solar units recorded no revenue in Q2FY27 or Q2FY26. The solar capacity is largely used internally to lower conversion costs.

Customer concentration also remains relevant to any increase in smelter demand. Alufluoride says its largest customer represented 54% of aluminium fluoride revenue in FY26, down from 69% in FY25, while the top two customers accounted for 72% and Odisha accounted for 70%. The presentation does not connect planned new smelter capacity to orders from either existing customers or new buyers.

Why does supplier qualification matter for Alufluoride?

Alufluoride says fewer than five manufacturers produce aluminium fluoride in India, and only a few qualify for high-purity, low-bulk-density supply. It says smelter qualification is slow and exacting because an off-spec consignment can damage potlines, making product quality, consistency and reliability important supply conditions.

The company says it is qualified at Hindalco, Vedanta and NALCO, the same three companies named in connection with about 1.55 MTPA of planned smelter additions. Alufluoride also cites Hindalco’s Resilient Supply Chain recognition and NALCO’s Best Customer award, but does not state that these qualifications secure future volumes.

Alufluoride says qualification is slow to win and slow to lose, which can affect how quickly competing suppliers can serve a new smelter. It is pursuing qualification with additional buyers and overseas markets through Alufluoride International Pte. Ltd., Singapore, though the presentation gives no target overseas volume or timetable.

The Visakhapatnam location is another supply mechanism identified by Alufluoride. The company says it is the only aluminium fluoride manufacturer in Andhra Pradesh and is within manageable freight range of every major Indian smelter. Its coastal plant is also on the same coast as both principal hydrofluosilicic acid suppliers.

What supply and cost factors could affect the opportunity?

Alufluoride converts hydrofluosilicic acid, or FSA, a fluorine byproduct of phosphatic fertiliser complexes, into high-purity aluminium fluoride. It says long-term contracts with IFFCO Paradeep and Coromandel International cover the bulk of feedstock needs, and an additional supplier plant was added from April 2026.

The company says further FSA quantities have been indicated following a supplier’s fluorine-recovery upgrade, without disclosing volume, timing or contractual status. Alufluoride maintains strict incoming-quality specifications across sources, consistent with its stated requirement to supply high-purity, low-bulk-density material to smelters.

Q2FY27 data show revenue increased faster than total expenses. Aluminium fluoride revenue rose 17% year on year to Rs 63.9 crore, while total expenses increased 2% to Rs 44.7 crore from Rs 43.9 crore in Q2FY26. Materials costs fell 13% to Rs 23.3 crore, while power and fuel costs rose 18% to Rs 8.7 crore.

Materials represented 36.4% of Q2FY27 revenue, compared with 48.8% in Q2FY26, according to Alufluoride. The company says alumina hydrate was bought ahead and prices were agreed in May 2026, while freight on FSA from distant sources is rising with fuel prices. Power intensity also increased to 332 kilowatt-hours per tonne in FY26 from 289 kilowatt-hours per tonne in FY25.

Conclusion

Alufluoride presents planned 1.55 MTPA Indian smelter capacity as a potential domestic demand pool of 21,600 to 30,900 tonnes of aluminium fluoride a year. That range is substantial relative to its 24,000 TPA plant capacity, but it remains an estimate based on consumption assumptions rather than disclosed orders, project-level volumes or supply commitments.

The next developments to watch are Vedanta’s stated additions by FY28 and NALCO’s indicated Angul smelter timing of 2030-31. Alufluoride is also evaluating a second aluminium fluoride site, but says a formal project commitment will follow only after specifications, capital cost, financing and revenue economics meet the board’s requirements.
