Description

Silicon Alloy, Base, Si,Ca,Mn CAS NO 11125-27-2 is a master alloy primarily composed of silicon, calcium, and manganese, designed for precise addition and modification of molten metals. This product is critical for achieving superior metallurgical control, enhancing mechanical properties, and improving the cleanliness of the final metal. It is an essential raw material for foundries and steel mills engaged in the production of high-quality cast iron, ductile iron, and various specialty steels.

Application

• Ductile (Nodular) Iron Production: As a key inoculant and nodularizer to promote the formation of spheroidal graphite, improving ductility and strength.
• Steel Deoxidation and Alloying: For efficient deoxidation (killing) of molten steel and precise adjustment of silicon, calcium, and manganese content in alloy steels.
• Gray and Compacted Graphite Iron: Used for inoculation to control graphite morphology, enhance mechanical properties, and reduce chilling tendency in castings.
• Desulfurization and Inclusion Modification: Calcium content aids in desulfurization and modifies the shape of non-metallic inclusions (e.g., sulfides, oxides), improving castability and product toughness.
• Secondary Metallurgy: Employed in ladle furnace treatments for final composition trimming and inclusion engineering.
• Production of High-Strength Low-Alloy (HSLA) Steels: To achieve specific strength, weldability, and formability characteristics.

Quality Control

Our Silicon Alloy, Base, Si,Ca,Mn is manufactured under strict process controls to ensure batch-to-batch consistency and reliable performance. Each lot is analyzed to verify critical composition parameters including silicon, calcium, and manganese content, as well as trace element levels. Certificates of Analysis (COA) detailing these results are provided and can be tailored to meet specific customer or industry standard requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated warehouse away from moisture and incompatible materials. Due to the reactive nature of fine metallic powders, keep away from strong oxidizers. Bulk material should be stored under cover to prevent contamination and moisture absorption.
