Bhubaneswar, Apr 3 (IANS): State-run National Aluminium Company Limited (Nalco) recorded excellent production and sales results during 2010-11, the company said Sunday.

While the company has achieved highest-ever cast metal production of 443,597 tonnes against the previous best of 431,488 tonnes achieved in 2009-10, sales of its metal was up to 438,952 tonnes in 2010-11 against the previous year's 435,979 tonnes, Nalco said in a statement.

The increasing demands and improvement in company's share in the domestic market is the reason behind the highest ever metal sale, the statement said.

Besides, Nalco's alumina refinery has achieved 98.8 percent capacity utilisation by producing 15.56 lakh tonnes of alumina hydrate, while its bauxite mines produced 48.24 lakh tonnes with a capacity utilisation of 100.5 percent.

Nalco's captive power plant at Angul also recorded the highest-ever net power generation of 6,608 million units, against the previous best of 6,293 million units achieved in 2009-10, the statement said.

The company also recorded the highest-ever domestic metal sale of 340,752 tonnes in 2010-11, surpassing the previous highest of 289,032 tonnes in the previous fiscal.

Nalco achieved a record sale of 20,022 tonnes of rolled products in the domestic market in 2010-11 against the previous best of 14,419 tonnes in 2009-10.

This year the company added aluminium T-Ingots to its product range, which is first of its kind in Indian aluminium industry.

Similarly, the company resumed its billet exports in 2009-10 after a gap of a decade and in 2010-11 it exported 4614 tonnes of billets.

More production and sale of rolled products and billets have increased the proportion of value added products in Nalco's operations.

Nalco has also widened its international customer base by adding new overseas clients during the year.
