Eutectic and hypereutectic aluminum-silicon cast aluminum alloys are widely used in applications such as engine pistons, air conditioning pistons, and various wear-resistant and lightweight parts. Due to the presence of coarse primary silicon, eutectic silicon and inevitable plate-like and needle-like iron phases in the microstructure of eutectic and hypereutectic aluminum alloys, the mechanical properties of the materials decline. It is necessary to refine the primary silicon and eutectic silicon by adding Pelement. After adding Mn element to refine the iron phase; Only in this way can the performance requirements of the parts be met. The aluminum-phosphorus alloy type modifier produced by our company belongs to the aluminum-based alloy type. It is prepared through advanced nano-melt technology and can simultaneously refine the primary silicon, eutectic silicon and plate-like iron in the microstructure of aluminum alloys. It also features excellent refinement effect and environmental friendliness.
