Used in aluminium wrought alloys and foundry alloys for composition adjustments and structure control.
Boron will from high melting compound 
Together with impurities and such compound

Furnace to clean the met

the recovery rates of some elements directly

Charged into molten metal in pure metal form

Are very low because of high melting point or

Low ignition or low wettability. the

Advantages of master alloys are lower melting

Point and higher recovery with uniform

Composition and low impurity content, which

Will reduce cost and improve efficiency for

Production.
