Product Description

Sr90Al10(AlSr90) 90 Aluminum Ingot,packed in sealed tubes

Strontium content in Strontium Aluminum master alloy can be produced according to customer’s requirement from 50-90%.

Strontium Aluminum master alloy Sr90Al10(AlSr90) is a high concentration modifier with a melting point of only 580. It is used for modification of AlSi5-13% alloy, especially for casting parts with high quality. Compared with the commonly used alsr10 modifier, Sr90Al10(AlSr90 has better modification effect,more uniform composition, lower adding temperature not only reduce the production energy consumption of the user but also makes it ideal for casting at lower metal temperatures,less addition amount can reduce the production cost, and has higher cost performance ratio.Sr90Al10(AlSr90) is also ideally suited for Strontium treatment in the ladles used by large aluminum foundries.


Strontium Aluminum alloy Sr90Al10(STRONAL 9010) Purpose        

Strontium Aluminum alloy Sr90Al10(STRONAL 9010) can be used in die casting, low pressure casting and modification of hypoeutectic and eutectic silicon alloy with long pouring time.

Aluminum Strontium master alloy differs from other modifiers in that it retains its modification effectiveness for extended periods of melt holding time.   

Modification of the morphology of the silicon phase in aluminium silicon alloy castings from coarse platelets to a fine fibrous eutectic structure results in improved soundness and mechanical properties.


Strontium Aluminum alloy Sr90Al10(AlSr90) Features            

Strontium Aluminum alloy Sr90Al10(AlSr90) is a long-term modifier with good structure. which is mainly used in the modification of hypoeutectic and eutectic aluminum silicon alloy, it has the following advantages:

1.Low melting point of 580

2.Better modification effect.

3.Lower cost of use.

4.The validity period of strontium modification is longer than 6-8 hours, 4-5 times of remelting still has modification effect, which can meet the needs of low-pressure casting and die casting with long duration, especially suitable for casting large casting parts and continuous production. Excellent state and distribution, improve mechanical properties and fluidity            

5.Easy to use, no pollution, less wastage, lower using cost, long working efficiency and hereditary effect.
