National Aluminium Company Limited (NALCO), a Navratna CPSE under the Ministry of Mines, Government of India, has launched a new IA91 Grade aluminium alloy ingot designed for high-performance casting applications. The product was formally introduced at NALCO’s Kolkata Stockyard by Anil Kumar Singh, Director (Commercial), in the presence of senior company officials.
IA91 is a silicon-based aluminium casting alloy developed to deliver a balanced combination of castability, mechanical strength and corrosion resistance. The alloy is suited for gravity die casting and low-pressure die casting processes and is expected to support a wide range of industrial applications, including automotive components, electrical and power equipment, and general engineering products manufactured by foundries.
The launch marks another step in NALCO’s strategy to expand its portfolio of value-added aluminium products for domestic and international markets. With demand for specialised alloys growing across sectors such as transportation, infrastructure and industrial manufacturing, IA91 is positioned to meet the requirements of customers seeking reliable performance and consistent quality in casting operations.
Speaking on the occasion, Brijendra Pratap Singh, Chairman and Managing Director of NALCO, congratulated the production and marketing teams for bringing the new product to market. He noted that expanding the company’s alloy range reflects its continued focus on innovation, customer needs and quality manufacturing.
