Product Description

With an aim to be a market leader in our domain, we are becoming as one of the leading manufacturers and suppliers of Cover Flux. It is powdery salt mixture which finds application in foundries. This flux is added to base of molten metal and then stirred for even distribution. It forms a protective layer on the surface of melt thus resulting in reduced oxidation. Offered Cover Flux is also known to have cleaning properties as it absorbs oxides from the walls of furnace or ladle.


  • Helps in higher metal recovery

  • Improves fluidity & wettability of dross entrapped metal

  • Enhances tensile strength of alloys



Cover Flux

Cover pink'  is a foundry flux used by aluminum smelting industry. This flux helps higher aluminum metal recovery from the dross. 'cover pink' is used in big capacity furnaces like oil/electric furnace.

This Flux is highly Exothermic in nature. The functions of this flux are almost equivalent to Cover flux SP- I .This flux is more suitable for Crucible Furnace and moreover for processing of dross. It gives best of Aluminum metal recovery from the dross. The application rate of this flux is 1%.

Product in Brief:

Aluminum and its alloys form a film of oxides during melting in open atmosphere. The density of this oxide film is just the same as of Aluminum and its alloys. Hence they are not readily separable and remain suspended in the melt which results in unsound casting and loss of precious metal.Thus prior to the casting of the metal, the removal of these suspended oxides from the melt is very much essential.

Cover fluxes when added to the melt, they form a protective cover over the melt and they curtail oxidation losses and minimize the hydrogen and carbon pickup. They also help in removing dirt and nonmetal ices and on skimming produce dross, low in metal content. There are various grades of Cover Fluxes, which are meant for different purposes.


It is altogether a general purpose covering flux for Aluminum melting. This flux is recommended 0.5% to 1% by weight of metal charge. The type of dross formed is dry in this flux Operation. As soon as the charge begins to melt, add half the quantity of flux and the remainder when the complete charge is molten. Once the flux is added, do not stir the metal or disturb the flux layer. Keep the cover intact as far as possible until the dross is removed.

Packing: 50 packets of 1 kg. Packed in 50 kgs. Double Polylined HDPE sacks, which is solid enough to withstand shakes and jolts of transportation.
