In 2026, with the continuous growth of downstream steel enterprises’ demand for high-end special steel (such as automotive sheet, pipeline steel, tire cord steel), High Purity Calcium Cored Wire has become the core direction of industry product upgrading. Traditional calcium cored wire products can no longer meet the strict requirements of high-end steel grades for trace element control accuracy (oxygen content ≤10-20ppm), while high-purity and customized High Purity Calcium Cored Wire has continued to expand its market share with the advantages of low impurities and high stability. According to industry research data in January 2026, the domestic market quotation of high-purity calcium cored wire (calcium content ≥97%) has risen to 9400-9800 yuan/ton. Supported by raw material costs, the price will remain stable with a slight upward trend in the short term.
Technical Upgrade Breakthroughs of High Purity Calcium Cored Wire
The core technological upgrades of High Purity Calcium Cored Wire focus on three aspects: first, the improvement of calcium core purity. Through special processes such as vacuum drying and nitrogen protection, the calcium content is stabilized above 97%, and the impurity content is controlled below 3%, which effectively reduces the risk of secondary pollution of molten steel; second, the optimization of steel strip coating process. Cold-rolled bright steel strip is adopted, with a thickness increased by 0.2-0.3mm compared with traditional products, which improves the product’s tensile strength and bending resistance, and avoids wire breakage during feeding; third, the optimization of core material uniformity. Through automatic filling equipment, the calcium core weight deviation is controlled within ±2g/m to achieve precise feeding.

Core Difference Comparison Between High Purity Calcium Cored Wire and Traditional Products
Compared with traditional calcium silicon cored wire, High Purity Calcium Cored Wire has significant advantages in core performance: first, the calcium recovery rate is increased by more than 52%, the calcium recovery rate of traditional products is only 8-10%, while that of high-purity calcium cored wire can reach 15-16.6%; second, the dosage per ton of steel is reduced by 62%, the feeding weight per ton of steel of high-purity calcium cored wire is only 38% of that of traditional products, which greatly reduces production costs; third, the application range is wider, which can adapt to the calcium treatment needs of various high-end steel grades such as aluminum killed steel, gear steel and bearing steel, while traditional products are mostly limited to plain carbon steel production.
2026 High Purity Calcium Cored Wire Market Trend Outlook
With the continuous tightening of environmental policies and the improvement of industry concentration (the industry CR5 is expected to exceed 35% in 2026), low-purity and low-performance calcium cored wire products will be gradually eliminated, and the market demand for High Purity Calcium Cored Wire will maintain a growth rate of more than 10% annually. At the same time, with the increase of electric furnace short-process steelmaking ratio, the demand for high-purity calcium cored wire will be further released. It is expected that the domestic high-purity calcium cored wire market scale will exceed 1.5 billion yuan in 2026.
