What Is High Carbon Silicon?

High carbon silicon (HC-Si) is an alloy of silicon and carbon, typically Si 60-68% with C 15-18%. It is used where the heat needs silicon and carbon together, in one charge material.

Bright Alloys supplies HC-Silicon Si60C15, Si65C15 and Si68C18 in lumps and granules, plus Si40C20 and Si50C20 powders for injection, briquetting and sintering.

Applications and Performance

Steel Deoxidation

Because it carries both silicon and carbon, HC-Si deoxidises the heat while adding carbon required by the grade, so fewer separate additions are needed.

Alloying in Electric Furnace Steelmaking

The higher-carbon 68-18 grade is used where precise carbon control is required in tool and specialty steels.

Powder Injection and Sintering

Si40C20 and Si50C20 powders suit injection metallurgy, briquetting and sintering, where a fine and free-flowing material is needed.

High Carbon Silicon Alloys FAQs

What is high carbon silicon alloy and how does it compare to standard ferro silicon? +

High carbon silicon alloy (also known as silicon carbon alloy) is a deoxidizer and carburizer containing approximately 60-68% Si and 15-20% C. Unlike standard ferro silicon, it provides both silicon and carbon, making it cost-effective for steel deoxidation and alloying. It is widely used in ladle furnaces and induction furnaces.

Which grade of silicon carbon alloy should I choose for steelmaking? +

The choice depends on your target carbon and silicon levels. For balanced deoxidation and carburization, our Si60 C15 grade is popular. For higher silicon efficiency, consider Si65 C15. For maximum carbon, Si68 C18 offers high C content. For powder injection processes, Si40 C20 powder is recommended. Contact our engineers for a free consultation.

What are the typical applications of silicon carbon alloy? +

High carbon silicon alloy is used in steelmaking for deoxidation, carburization, and alloying. It replaces part of the need for ferro silicon and carbon additives, reducing costs. It is suitable for carbon and low-alloy steel production, foundry iron inoculation improvement, and ladle refining. See our full product line for more options.

Can I get a custom specification of high carbon silicon? +

Yes, Bright Alloys can tailor the Si/C ratio, particle size (lumps, granules, powder), and packaging according to your operational requirements. Use our Request a Quote form to specify your needs, and our team will provide a competitive offer with quality certification.
