Import Calcium Granules — Buy in Bulk from Supplier in China

Calcium granules from Hebi Changhong Magbesium Co., Ltd are a metallurgical additive used in steel and iron production, serving as a deoxidizer, decarbonizer, and desulfurizer during alloy smelting. The product is also employed as a reducer in high-purity rare earth extraction, and in manufacturing lead-calcium-tin batteries and pharmaceuticals. Packaging involves polybags filled with argon gas, sealed inside steel drums to prevent oxidation and maintain purity during transit and storage.

The granules are composed of calcium metal, typically supplied in sizes ranging from 1 to 10 mm for industrial use. In metallurgy, calcium is valued for its strong affinity for oxygen, sulfur, and carbon, which improves the cleanliness and mechanical properties of steel. Standard calcium metal for such applications usually achieves purity levels of 98.5% to 99.5%, with trace elements like aluminum, magnesium, and nitrogen controlled to ensure consistent performance. Typical impurity thresholds for metallurgical-grade calcium include aluminum under 0.5%, magnesium under 0.3%, and nitrogen under 0.1%.

Steel mills, foundries, and battery manufacturers are the primary buyers, sourcing calcium granules for large-scale production runs. The argon-filled polybag packaging is critical for preserving reactivity, as calcium metal oxidizes rapidly when exposed to air. Buyers should confirm the exact granule size distribution and purity specifications to match their process requirements, as variations can impact reaction efficiency in smelting or chemical synthesis.

Hebi Changhong Magbesium Co., Ltd is based in the Jinshan Industrial Park, Qibin District, Hebi, Henan Province, China. The company operates as an imported-tier supplier specializing in metallurgical additives, with a focus on calcium-based products for industrial applications. Its address at Longgang Road No. 2 places it within a recognized industrial hub for metal processing and refining.

The supplier’s trust tier is classified as harbor, indicating a baseline level of verification. However, its response rate is currently recorded at 0.00%, with no average response time logged. This suggests limited engagement on the platform, so buyers should expect to follow up through alternative contact methods to confirm availability, technical specifications, or trade terms.
