Ferro Silicon Calcium (CaSi) is a ferroalloy composed of calcium (Ca), silicon (Si), and iron (Fe). It is widely used as a deoxidizer, desulfurizer, and alloying agent in steelmaking and foundries. The addition of calcium improves steel quality by removing impurities like oxygen, sulfur, and phosphorus, while silicon enhances strength and corrosion resistance.


Chemical Composition:

✅ Calcium (Ca): 24-30%

✅ Silicon (Si): 55-65%

✅ Iron (Fe): Balance

✅ Carbon (C): ≤ 0.1%

✅ Sulfur (S): ≤ 0.03%

✅ Phosphorus (P): ≤ 0.03%

Key Features:

✅ Excellent Deoxidizer & Desulfurizer: Removes unwanted impurities from steel and iron.

✅ Improves Steel Quality: Reduces inclusions, improving machinability and surface quality.

✅ Enhances Alloy Properties: Increases hardness, corrosion resistance, and weldability.

✅ Available in Various Sizes: Supplied as lumps, granules, or powder.

Applications:

✅ Steel & Foundry Industry: Used in low-carbon and high-strength steels.

✅ Cast Iron Production: Improves mechanical properties and removes sulfur.

✅ Welding Electrode Manufacturing: Enhances weldability and arc stability.

✅ Specialty Alloys & Ductile Iron: Used in the production of magnesium ferrosilicon alloys.
