This product is formulated with a variety of salt compounds through dehydration and refining. It can be used for modification of sand casting or thick-walled casting and can deliver good modification performance.

Properties: white powder, 2.5kg/pack.

Applicable to: hypo-eutectic and eutectic Al-Si alloys with Si content ranging from 6% to 13%.

Processing Temperature: 700℃~730℃

Recommended Dosage: 1.0% ~ 2.0%

Features and Benefits:

1.Low processing temperature; good and stable modification effectiveness.

2.More refined casting grains; improved mechanical performance of alloys, especially in terms of plasticity.


Spread a certain amount of the product on the surface of the melts. Keep still for 10 ~ 12 minutes. Stir the melts and allow the product to go to the deep of the melts. After 3 ~ 5 minutes, clean off the slags and cast a rod for fracture testing. When the modification meets set standards, start to cast.


Insufficient modification: fracture is dark gray, big grain size, visible Si spots.

Proper modification: fracture is silver white velvet-like shape, even grains, no visible Si spots.

Over modification: steel gray fracture and eutectic accumulation due to overdosing.

Packaging and Storage:

Pack in plastic bags with corrugated boxes or woven bags as secondary packaging. 20kg or 25kg per box. Store with caution in a dry place and avoid damp.
