Cast Iron Foundry in India
Precision Ductile Iron & Grey Iron castings from Coimbatore for global industries
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.
