SODIUM:
Aluminum alloys used in silicon foundry to modify the thick plates of silicon and transform them into fine fibers.
STRONTIUM METAL ADDITIVE:
The additive metal strontium silicon aluminum alloys used in casting, to modify the thick plates of silicon and transform them into fine fibers.
The additive 10% 90% strontium aluminum is effective within minutes after adding the molten metal, due to the exothermic reactions of the switch to low melting temperatures.
Strontium can also occur at 100% purity for the composition of mothers leagues.
ADVANTAGES:
Improved tensile strength and fatigue.
Avoid needle tips in the piece
It dissolves rapidly without producing any smoke or fumes.
Contains less than 0.2% iron and 5 ppm. phosphorus.
It contains silicon, which can cause hard spots in foundries.
APPLICATIONS:
Preparation casting
Modification of silicon.
Recommendations for use: Add surface
Add under the clean surface of molten metal and allowed to dissolve for three to five minutes. Mix bath at temperatures below 720 ° C., 740 ° C possibly more if the temperature is higher.
It is recommended at the last moment before entering the molten material to the piece.
Ratio Using 250gr. 100 kg. Aluminum.
(In the form of wire 1.30 meters = 250gr.)
ADD IN THE BUCKET:
Take a metal spoon and add pre-heated strontium. As the temperature drops the bucket, the additive will dissolve and then be reinstated in the melt.
