• Purpose:
High-carbon silicon is used in the production of cast iron, which can enhance the fluidity of the castings, reduce shrinkage cavities and gas pores, and improve the quality of the castings.
As a seed crystal, it promotes graphitization and enhances the mechanical properties of gray cast iron and ductile cast iron.
• Application scenario:
Produces castings such as engine cylinder blocks, brake discs, pipes and mechanical parts.
• Trend in 2025:
With the increasing demand for lightweight castings (such as aluminum alloy and cast iron composite materials), the application of high-carbon silicon in the casting industry is likely to expand further.
