Classification Of FeTi
Classification by Titanium Content
Low-Grade Ferrotitanium (10-30% Ti)
Composition: 10-30% Ti, 65-85% Fe, balance impurities (Al, Si, C)
Characteristics:
Most economical option
Higher iron content improves fluidity in steelmaking
Contains more impurities than higher grades
Applications:
General steel deoxidation
Low-cost alloying in construction steels
Foundry applications
Medium-Grade Ferrotitanium (30-50% Ti)
Composition: 30-50% Ti, 45-65% Fe, reduced impurities
Characteristics:
Balanced cost-performance ratio
Better grain refinement than low-grade
More consistent quality
Applications:
Stainless steel production
HSLA (High-Strength Low-Alloy) steels
Automotive components
High-Grade Ferrotitanium (50-75% Ti)
Composition: 50-75% Ti, 20-45% Fe, minimal impurities
Characteristics:
Premium quality with precise composition
Excellent grain refinement
Superior mechanical properties
Applications:
Aerospace alloys
Specialty steels
High-performance welding electrodes
Classification by Production Method
Aluminothermic Ferrotitanium
Process: Reduction of titanium ores using aluminum
Characteristics:
Higher purity (70-75% Ti possible)
Lower carbon content
More expensive process
Typical Uses: Aerospace, defense applications
Carbon/Silicon Reduced Ferrotitanium
Process: Electric arc furnace reduction
Characteristics:
Lower cost
Higher carbon/silicon content
Typically 30-50% Ti range
Typical Uses: General steelmaking
Electrolytic Ferrotitanium
Process: Electrolysis of titanium compounds
Characteristics:
Highest purity (>75% Ti)
Very low impurity levels
Most expensive production method
Typical Uses: Critical aerospace components
Special Classification: Ultra-Low Impurity FeTi
