Our laboratory is an expert in metallurgy and analysis of alloys, especially CaSi, and offers its expertise to analyze the chemical composition and control of metal alloy grades.
Your need: perform a calcium/silicon alloy analysis (CaSi)
The CaSi alloy, or calcium silicide, is a metal compound consisting mainly of calcium (Ca) and silicon (Si). It is widely used in the metallurgical industry, especially for the processing of steels and cast iron.
The CaSi alloy, or calcium silicide, is in the form of a metallic solid whose colour varies from grey-white to black. It is available in several formats adapted to industrial needs: pieces, granules, powder or filled wires, with sizes generally ranging from 0 to 100 mm.
There are several types of CaSi (calcium silicide) alloys, differentiated mainly by their content in calcium (Ca) and silicon (Si). These variations make it possible to adapt the alloy to the specific needs of metallurgical processes, particularly in the iron and steel industry and in foundries:
The different types of CaSi
The CaSi alloy is an essential component in metal processing, offering significant advantages in terms of purification and improvement of mechanical properties of steels and cast iron.
CaSi alloys are generally classified according to their chemical composition. Some common examples include:
Analysis of the composition of CaSi: an essential quality control
Analysis of the chemical composition of CaSi allows verification of the presence and concentration of essential alloying elements, such as calcium, silicon or iron, Ensuring material compliance for safety and performance-critical applications.

Why choose our laboratory for the analysis of CaSi?
Our FILAB laboratory offers services dedicated to the analysis of CaSi and its alloys, adapted to the specific needs of each industry. Performing a calcium/silicon composition analysis can address several industrial issues:
- Powerful deoxidizer: calcium and silicon have a strong affinity for oxygen, which makes it possible to effectively remove oxides during the manufacture of steel.
- Desulfurizer: calcium reacts with sulphur to form stable compounds, reducing the sulphur content of steel.
- Inclusion modifier: it modifies the shape and distribution of non-metallic inclusions, improving the cleanliness and mechanical properties of steel.
- Casting inoculant: in the production of grey cast iron, it promotes the formation of finely distributed graphite, improving the mechanical properties of the cast iron.
CaSi is widely used in:
- The iron and steel industry: for the deoxidation and desulphurization of steel.
- Foundry: as inoculant to improve the structure of graphite in grey cast iron.
- The production of filled cores: CaSi is often incorporated into filled wires for controlled introduction into molten metal.
Yes, there are several types of CaSi alloys, differentiated mainly by their content in calcium (Ca) and silicon (Si). These variations make it possible to adapt the alloy to the specific needs of metallurgical processes.
The CaSi is available in several formats adapted to industrial needs:Made in China
- Chunks (lumps): used for direct addition into ovens.
- Granules: allow a more uniform distribution in the metal bath.
- Powder: used for applications requiring rapid reactivity.
Cored wires: provide precise control of alloy addition, improving process efficiency and safety.
