Nalco Launches IA91 Grade Aluminium Alloy Ingot

05 Mar 2026 CW Team

IA91 is a high performance silicon based casting alloy engineered to deliver an optimal balance of castability, mechanical strength and corrosion resistance. The alloy has been developed for gravity die casting and low pressure die casting techniques and is intended for applications in the automotive, electrical and power equipment, industrial sectors and foundries. The material properties are expected to meet the demands of advanced casting applications. The specification is intended to offer consistent performance across batch production and to facilitate predictable machining outcomes.

NALCO indicated that the new product forms part of an expanding range of value added offerings designed to support downstream industries. The chairman and managing director conveyed congratulations to the production and marketing teams and stated that the broadened product portfolio demonstrates the company's ongoing commitment to delivering quality. Company officials noted that the launch aligns with strategic priorities to enhance product mix and promote higher value realisations.

Distribution of the IA91 ingot will be handled through existing stockyards and marketing channels with information also available on the company website. The development is likely to provide foundries and component manufacturers with a domestically produced silicon based alloy alternative and to support efforts towards localisation and industrial competitiveness. Market feedback and internal trials are expected to inform incremental refinements to ensure wider industry acceptance. The corporate communication department issued the formal announcement.

Instead of asking visitors to browse stone as commodity, it stages the material as experience – dramatic, tactile, immersive and unmistakably architectural. Spread across 6,000 sq ft, the centre is not conceived as a conventional showroom but a ‘Stone Theatre’: a place where stone is read, felt and understood before it is bought. If natural stone is one of the m..
