    Cast Iron Foundry in India

    Precision Ductile Iron & Grey Iron castings from Coimbatore for global industries

    About Our Foundry

    A Nationwide Casting Supplier from Coimbatore

    Sri Gnanamurugan Foundry has manufactured grey iron and ductile iron castings since 1992, supplying OEM manufacturers and engineering companies across India — from automotive and pump manufacturers in the south to construction and general engineering customers nationwide. Every casting is produced under one ISO 9001:2015 certified process, whether the order ships within Tamil Nadu or across state lines.

    Castings are supplied to Indian Standard (IS 210 / IS 1865), and to EN, ASTM or DIN specifications where a customer's drawing calls for it. Every batch is issued a Material Test Certificate in the BIS Annexure-I format, so a buyer anywhere in India receives the same documented, traceable quality as a customer next door in Coimbatore.

    Ductile Iron vs Grey Iron

    Ductile Iron (formerly SG Iron) offers high strength, toughness, and flexibility, making it ideal for load-bearing applications.

    Grey Iron provides excellent machinability and vibration damping, making it suitable for automotive and machinery components.
