Ferrophosphorus, an alloy primarily composed of iron and ferric phosphide, plays an indispensable role in modern metallurgy. This gray, slightly lustrous alloy is mainly produced through electric furnaces due to its unique properties that make it essential in the manufacturing processes of various metals. This article will delve into the applications of ferrophosphorus across different sectors such as steel, aluminum, and copper, highlighting its significant advantages. Additionally, it will introduce Lishi as a reliable supplier of ferrophosphorus.

Applications in the Steel Industry

In steel production, ferrophosphorus is used to precisely adjust the phosphorus content in metals to any desired level. For cast iron, when the phosphorus content is controlled within the range of 0.2% to 0.9%, the fluidity of the molten metal increases significantly. In the sanitary ware industry, adding phosphorus up to 0.8% greatly improves the casting performance, enabling the production of large and thin castings. Moreover, for small and complex castings like piston rings, decorative iron pieces, and hardware, the addition of ferrophosphorus can enhance their quality by improving flowability or toughness. When the phosphorus content in cast iron reaches 0.75%, the ability of the casting to withstand repeated heating and cooling improves. This phosphorus content inhibits the decomposition of cementite into ferrite and graphite carbon, thereby limiting the growth of the casting. It also provides an iron-phosphorus eutectic network that effectively prevents the penetration of oxidative gases, further enhancing the quality of the castings.

Applications in Other Metals

Beyond the steel industry, ferrophosphorus finds applications in aluminum and copper production. Adding phosphorus to aluminum alloys changes their crystal structure, thus improving their physical properties, especially for high-strength aluminum alloys containing up to 20% silicon. In copper-based alloys, adding at least 0.05% phosphorus not only increases the fluidity of the alloy but also serves as a deoxidizer, contributing to its purity and mechanical properties.
