Non-Ferrous Metal Industry
Aluminum smelting and copper refining punish inconsistent carbon inputs: anode-grade CPC must behave predictably in the cell, while refining lines need deoxidation paths that hit oxygen and impurity budgets without side reactions. That is why non-ferrous customers specify carbon raiser, SiC, and related metallurgical products for both electrochemical and pyrometallurgical steps. We focus on purity, consistency, and application-matched sizing so carbon additive strategy supports current efficiency, metal cleanliness, and repeatable refining outcomes.
Application Overview
Carbon & Alloy Solutions for Non-Ferrous Metal
Non-ferrous routes—from Hall–Héroult aluminum cells to secondary copper and specialty alloys—depend on carbon and silicon carbide inputs that respect conductivity, reactivity, and trace impurity envelopes. Anode-grade carbon materials must support stable cell operation and metal quality; deviations in density or impurities can show up as dusting, instability, or off-spec metal. In copper, deoxidizer selection (including SiC-based practice where it fits the flowsheet) ties to oxygen control for conductivity-critical grades. High-temperature melting and refining still use carbon and SiC where chemical reduction, slag control, or exothermic contribution matters. Our portfolio is positioned for these roles with grades and sizing aimed at furnace type and quality targets—not generic “carbon in, metal out” supply.
Industry Challenges
- Achieving <0.1% impurity levels in aluminum, copper, and specialty alloys where trace elements affect conductivity and corrosion resistance
- Effective deoxidation in copper refining where dissolved oxygen must be reduced to <10 ppm for high-conductivity grades
- Managing the carbon consumption rate in Hall-Héroult aluminum cells to maintain anode quality and minimize carbon dust generation
- Reducing specific energy consumption in electric furnaces through exothermic deoxidizer selection and optimized charge practices
- Meeting aerospace-grade alloy specifications (AMS, ASTM) where trace element limits are measured in single-digit ppm
