Features of Goods

AlSr10 stick（tablet）is an excellent modifying agent to aluminium alloys,it can refine the grain of silicon in the alloy,improves the mechanical capacity of the alloy,the modifying operation has long-effect,stability in remelting and anti-decay properties.No pollution,simple adding machining,no erodent effects.

Chemical Composition
Mail elements are as follows:

Elements      Composition%
Sr                       9~11
Si                        <0.16
Fe                       <0.25
V                         <0.1
Al                       Others

Directions for use
After the melt transferred into the ladle or vacuum furnace,add the grain-refiner into the ladle or vacuum furnace with required amount.The quantity should be 0.2-0.4%,the required temperature is 720-7400C,skim off the dross before adding,then remove equally,removing can be done by FDU(foundry degassing unit) while refining and degassing,and also can be done manual,stay still for some time before using.
