Metallurgical SiC brings both Si and C and keeps nucleation alive longer than FeSi. How much FeSi and carbon it replaces, when to add it, and the break-even price.
Si Metal 441 (Fe≤0.4%, Ca≤0.1%) vs 553 (Fe≤0.5%, Ca≤0.3%): Al-Si casting intermetallics, Rochow-process trace-element control, and the real grade-cost call.
Choosing between high-carbon ferromanganese and ferrosilicomanganese: deoxidation, desulfurization, dosage math and EAF bath chemistry. Mn ≥65% spec, per-ton cost difference.
The EU Carbon Border Adjustment Mechanism entered its definitive phase on 1 January 2026. EU ETS ~€75/tCO₂e, embedded-emissions declarations, and the impact on the Turkish EAF exporter's ferroalloy sourcing decision.
The 10-minute critical window from nodularization to pour. Mg fade physics, FeSiMg particle size logic, and numbers from a Turkish foundry case.
China's FeMo export licensing entered month 14. Price impact, Turkish EAF response, and a multi-regional supply framework for H2 2026.
