Modifiers
Optimized Microstructure.Superior Castings.
ARK Modifiers are precision AlSi master alloys formulated for Al-Si casting alloys. Designed to refine eutectic silicon into a fine, fibrous structure, they improve feeding behaviour, enhance ductility and machinability, and deliver consistent metallurgical quality in every casting.
Why Modifiers?
Improved Ductility
Transforms coarse silicon into a fine fibrous structure for enhanced toughness and elongation.
Reduced Shrinkage Porosity
Promotes more uniform solidification and improved casting integrity.
Enhanced Surface Finish
Produces smoother surfaces and improved dimensional consistency.
Better Machinability
Refined silicon morphology reduces tool wear and improves machining performance.
Consistent Metallurgical Quality
Delivers repeatable modification performance across production batches.
