Import Calcium Silicon (Casi) — Buy in Bulk from Supplier in China

Calcium Silicon (CaSi) supplied by Changxing Ferroalloy Resources Co., Ltd is a calcium‑silicon alloy used as a deoxidiser in steel production. The alloy contains a minimum of 30 % calcium and at least 58 % silicon, with aluminium limited to 1.5 % maximum, carbon to 1.0 % maximum, phosphorus to 0.04 % maximum and sulfur to 0.05 % maximum. Particle sizes are offered in 0‑1.6 mm, 0‑2 mm and 10‑50 mm ranges, with a 90 % passing rate or custom sizes per customer requirement. The material is packed in 1 tonne big bags for bulk handling.

Within the ferro‑alloy market, calcium silicon grades generally target silicon contents between 55 % and 65 % to optimise deoxidation efficiency. The listed composition aligns with standard specifications for ladle treatment, where impurity limits for aluminium, carbon, phosphorus and sulfur are critical to achieve clean steel. Typical bulk density for this alloy is around 2.7 t/m³, and moisture levels are kept below 0.5 % to preserve reactivity. These parameters are consistent with the ISO 9001‑based quality expectations of most steel manufacturers.

The product is purchased by steel mills, foundries and metal‑casting facilities that require reliable deoxidising agents to improve steel cleanliness and mechanical properties. Buyers usually arrange shipments on FOB or CIF terms and negotiate minimum order quantities directly with the supplier; exact MOQ and lead times are not disclosed in the listing and should be confirmed. While the supplier mentions compliance with standard industry certifications, request copies of any test reports before finalising the contract. Payment methods and inspection arrangements are typically negotiated on a case‑by‑case basis.
