The OTG Inoculant Series was developed to meet a variety of needs manufacturing cast products. Our full-featured lineup includes everything from Silicon-based to graphite-based products accommodating a wide variety of applications such as ladle inoculation, in-furnace inoculation, and late inoculation.
Si is an important inoculant that promotes graphite spheroidization in cast iron and inhibits chilling. It offers excellent diffusibility and deoxidation effects, contributing to improved molten metal quality.
These are Si inoculants with a Fe-Si alloy base.
| Product | Features |
|---|---|
| CALBALLOY | All-purpose inoculant with enhanced effects and contains calcium (Ca), aluminum (Al), and barium (Ba). It delivers long-term chill prevention and significantly improves graphite shape and structure. |
| INOBEST-50 | This 50% Si-based inoculant is our most versatile option and offers stable chill prevention performance. It has a high specific gravity and low melting point, providing excellent cost performance. |
| SILLIMATE | This 75% Si-based inoculant is designed for versatility and minimal slag. |
Calcium (Ca) possesses properties that prioritize reactions with sulfur and oxygen in molten metal and is an important element in graphitization. Adding the appropriate amount according to the material helps improve graphite shapes. Because even a small amount produces a powerful reaction, it is incredibly effective when used properly. OTG offers technical support on usage and adding the optimal amount, so please feel free to reach out to us.

|---|---|
| HICALLOY | Ca-based inoculant that improves mixing and aims to maximize Ca inoculation effects. It also improves graphite shapes and tensile strength. |
| HICALLOY SUPER | High-concentration Ca-based inoculant that improves mixing and aims to maximize Ca inoculation effects. It also improves graphite shapes and tensile strength. |
| CHILLTOLL-A | Ca-based inoculant that prevents inverse chill and chill in ultra-thin products, improves fluidity, promotes ferritization in FCD, and offers superb improvements to the graphite grain number. |
| Product | Features |
|---|---|
| INOGRA-G | Highly cost effective inoculant that contains graphite, helping suppress chilling, and improves shrinkage in FC when a small amount is added. |
| INOGRA-GFT | This formula improves on INOGRA-G for better inoculant mixing. |
| INOGRA-GNF | This formula improves on INOGRA-GFT, eliminating environmentally hazardous substances in the latest graphite-based inoculant. |
| ULTRA-G | This inoculant allows simultaneous graphite and strontium (Sr) inoculation. It also offers excellent graphitization and suppresses shrinkage and is optimal for thin, small item casting. |
Sr is known for maintaining inoculation effects in gray cast iron and aiding the precipitation of graphite as well as minimizing chill depth compared to other elements, offering superior chill prevention. Compared to other inoculants, Sr-based inoculant does not result in increased eutectic cells, making it effective for improving shrinkage.
| Product | Features |
|---|---|
| ULTRA SILICON | Inoculant for FC, maximizing the inoculation effects of aluminum (Al), calcium (Ca), and strontium (Sr). |
Zr is an element that contributes to creating very fine graphite and forms fine spheroidal graphite structures in ductile cast iron. Because Zr easily combines with oxygen, sulfur, and nitrogen, it can suppress the occurrence of nitrogen defects.
| Product | Features |
|---|---|
| ZIRCALLOY | High-performance inoculant containing zirconium (Zr), barium (Br), and calcium (Ca). |
| CALZILAN | Superior inoculant with optimized zirconium (Zr), lanthanum (La), and aluminum (Al) content. It improves the graphite grain number and shrinkage in FCD. |
| Product | Features |
|---|---|
| NODULUP-1A, 1B | Inoculant containing bismuth (Bi), which helps significantly increase the graphite grain number in FCD and suppresses chilling. |
| SFSILICON-N | High-performance inoculant with optimized sulfur (S) and calcium (Ca) content for an increased graphite grain number in FCD and superb cost performance. |
| RARETRIM | Includes lanthanum (La) for an increased graphite grain number in FCD, and improved chill suppression and shrinkage. |
| Product | Features |
|---|---|
| IT-ALLOY | Inoculant that improves the base molten metal properties when added to an electric furnace. |
| ZERO-ALLOY | Groundbreaking in-furnace inoculant that improves the molten metal properties when added to an electric furnace and maintains effects for a long period of time. |
| Product | Features |
|---|---|
| CALBALLOY | Versatile CALBALLOY molten flow inoculation containing calcium (Ca), barium (Ba), and aluminum (Al). |
| CALBALLOY-M2 | CALBALLOY for direct pour inoculation with improved mixing. |
| NUCLEAR-S | Direct pour inoculant that enables graphite refinement by including sulfur (S). |
| CALBAMOLD-CB | Standard shape solid late inoculant used inside the mold or set in the pouring gate. |
| I.P.M | Powdered late inoculant used inside the mold. |
| CALBAMOLD-BARA | Block form late inoculant used in the pouring basin. |
| Product | Features |
|---|---|
| INOPARA-A | Contains antimony (Sb) to stabilize the formation of pearlite in the FC matrix structure. It can also suppress the formation of chunky graphite in FCD. |
| INOPARA-B | Inclusion of copper (Cu) and tin (Sn) helps densify the matrix and form pearlite in FC and FCD. |
