Key Features of FeSi 75% High-Quality Alloy​

• •
  Optimal Silicon Content: With ~75% silicon (Si) and the remainder primarily iron (Fe), it strikes a balance between deoxidizing efficiency and cost-effectiveness, avoiding excessive brittleness from higher Si levels.
• •
  Low Impurity Profile: Premium grades minimize harmful elements like phosphorus (P < 0.04%) and sulfur (S < 0.02%), ensuring stable chemical reactions in metallurgical processes.
• •
  Thermal Stability: It retains structural integrity at high temperatures (up to 1500°C), making it suitable for extreme industrial environments such as steelmaking furnaces.

Primary Applications Across Industries​

• •
  Steelmaking: Acts as a deoxidizer to remove oxygen from molten steel, preventing defects like porosity. It also adjusts steel’s silicon content—critical for electrical steels (high Si enhances conductivity) and spring steels (improves elasticity).
• •
  Cast Iron Production: Enhances graphite formation during casting, refining grain structure for stronger, more machinable cast iron components (e.g., engine blocks, pipes).
• •
  Welding Electrodes: Serves as an alloying agent to boost electrode strength and arc stability, ensuring consistent weld quality in construction and manufacturing.
