Top Inoculants for Foundry Industry in India – Discover Nortech’s Expertise

 🔩 Small Additions, Big Impact – The Role of Inoculants in Modern Casting

In the foundry industry, achieving perfect cast iron components depends on more than just molten metal—it depends on precision additives known as inoculants. These metallurgical agents control the shape, size, and distribution of graphite within the casting. The result? Enhanced strength, reduced chill, and improved machinability.

 Nortech’s inoculants are introduced at the furnace stage to ensure ideal graphite formation and controlled solidification.

For decades, Nortech Ferro Alloys Pvt. Ltd. has remained the go-to inoculant manufacturer for India’s foundries, supplying both domestic and international markets with premium-quality inoculants that consistently outperform industry standards.

🧪 What Are Inoculants?

Inoculants are ferroalloy additives introduced to molten iron to influence graphite structure formation during solidification. Their role includes:

• Promoting graphite nucleation

• Preventing carbide (white iron) formation

• Reducing chill depth

• Enhancing casting machinability

• Improving mechanical strength and performance

They are essential in both gray iron and ductile iron casting.

🏭 Types of Inoculants Supplied by Nortech

Nortech offers a comprehensive range of inoculants designed for high-efficiency performance in various foundry operations.

1. Ferro Silicon (FeSi) Inoculants

A widely used base inoculant with 70–75% silicon. Suitable for general gray iron casting.

2. Calcium Silicon (CaSi) Inoculants

Enhances nodule count and reduces chill. Ideal for thin-section ductile iron parts.

3. Barium-Based Inoculants (FeSiBa)

Offers superior chill control and fade resistance, ensuring graphite structure integrity in long pour times.

4. Aluminium-Calcium Inoculants

Used for producing balanced microstructures in complex ductile iron castings.

5. Rare Earth (REFeSi) Inoculants

Recommended for critical components requiring excellent nodularity and minimal carbide.

6. Custom Inoculant Blends

Nortech formulates inoculants specific to your furnace type, melt conditions, and casting applications.
