Ferrophosphorus is a widely used ferroalloy in the steelmaking and foundry industries, valued for its ability to enhance mechanical properties and improve melt behavior during production. It is primarily composed of iron and phosphorus, typically containing 18% to 23% Phosphorus, and is usually produced as a by-product during the smelting of phosphate-containing iron ores.

At KATCO Group Company, a trusted supplier of Ferroalloys and Casting Raw Materials, ferrophosphorus is offered with controlled chemical composition and consistent quality to meet the demanding requirements of modern metallurgical processes.

Ferrophosphorus

Chemical Composition and Characteristics

Ferrophosphorus is characterized by:

  • High phosphorus content

  • Good solubility in molten iron and steel

  • Relatively low melting point compared to pure iron

These properties make it an efficient and economical source of phosphorus in steel and cast iron production.

Role of Ferrophosphorus in Steelmaking

In controlled amounts, phosphorus can positively influence the performance of steel and cast iron. The addition of ferrophosphorus provides several metallurgical benefits:

  • Improved fluidity of molten metal, enabling better mold filling in casting operations

  • Increased hardness and wear resistance, especially in specific steel and cast iron grades

  • Enhanced machinability in certain applications

  • Cost-effective alloying, compared to using pure phosphorus

Because of these advantages, ferrophosphorus is frequently used in the production of Phosphorus alloy steels, wear-resistant cast irons, and specialty foundry products.

Industrial Applications

Ferrophosphorus is commonly applied in:

  • Steelmaking as a phosphorus additive

  • Foundry operations to improve castability

  • Production of wear-resistant and structural steel grades

  • Powder metallurgy and electrode manufacturing

Its use is particularly beneficial where improved melt flow and surface finish are critical.
