Inoculant (FeSiBa Inoculant)

Product Overview

Inoculant is an additive widely used in the production of gray iron and ductile iron castings. It is designed to improve the microstructure of cast iron, promote graphite precipitation, enhance mechanical properties, and reduce casting defects.

Most inoculants are based on ferrosilicon and contain additional elements such as barium (Ba), strontium (Sr), and calcium (Ca). Among them, FeSiBa Inoculant (Barium-Based Inoculant) is one of the most commonly used products in the foundry industry.

By improving graphite formation and reducing chilling tendency, inoculants play a critical role in producing high-quality castings with stable performance.

Tiegu delivers high-quality, standards-compliant ferroalloys to international buyers, ensuring reliable supply and consistent quality across the production chain.
