These fluxes are used for cleaning aluminium
and its alloys (molten form).
Due to heavy oxidation of aluminium during
there is high rate of casting rejection. It
into metal loss also.
Coverflux dissolves this oxide and other non-
metallic impurities from the molten metal.
This flux is to protect metals from surface
and protects metal against gas absorption
Increase in purity
Reduction in melting
Degassers are used to remove hydrogen and non-
molten metal to eliminate porosity in
Hydrogen pick up can deteriorate mechanical properties
cause pin holes in castings. Degassers eliminates
refines grains and improves mechanical
Degassing is most affective when pushed in the
metal bath in
a form of a tablet and with the help of Plunger.
Titanium and Boron based grain refiners help in
Mechanical properties of the metal with the help
nucleation. They are supplied in a tablet form
and are most
suitable grain refiners to give the best refinement
Diecoats are generally water based lubricants
for pressure and
gravity die castings of Aluminium.
Diecoats form lubricating film on the dieface which
acts as a barrier
between the molten metal and dieface to avoid
also helps in easy stripping of castings from
Reduces casting stains, Reduces rejections,
