Fluxes for Copper & Nickel Alloys
Recommended For
Coppercleaner standard powder or Cleanex Block B Briq Coppercleaner-20 powder, Coppercleaner-20 Briq (oxidizing fluxes for covering and cleaning (Copper and Nickel Alloys)).
Copper alloys containing Tin and Nickel will readily absorb hydrogen from combustion products, humid atmosphere and other source of moisture. When metal containing dissolved hydrogen the gas appears as voids or cavities in the casting. Oxidising coppercleaner fluxes prevent hydrogen pick-up, cleans metal and give pressure tight casting with improved mechanical properties.
1.Provides the two-fold action scavenging the metal and providing a protective cover.
2.Prevents hydrogen pick-up and cleans metal.
3.Improves physical properties of the metal and ensures sound and pressure tight castings.
Metalcleaner 49 Metalcleaner 8 (Reducing fluxes for covering and protecting Copper and Copper Zinc alloys)
Melting copper-zinc alloys require non oxidizing conditions and also need additional precaution to prevent zinc fuming. Alloys poured Without covering fluxes show abnormally high metal content in the dross and often require the addition of alloying elements.
1.Prevents absorption of harmful gases.
2.Melting loss and Zinc fuming are significantly reduced.
3.Metal-free drosses are obtained
4.Slag build-up on crucibles and furnace linings is greatly reduced.
Alberol\Alberol2 (Flux for covering and reducing oxide formation and inclusions in Aluminium, Manganese and Silicon Bronzos)
During melting, Copper base Alloys containing Aluminium, Mangananese and silicon have great affinity for oxygen which forms large amounts of oxides in the form of heavy dross. When the metal solidifies these insoluble oxides develop a fine film at the grain boundaries which impairs proper feeding of the casting and weakens the Alloy's structure. In subsequent fabrications these oxides are revealed as long films in extrusions and rolled sheet, shortening die life and resisting movement through the extrusion press, in forging the oxides induce cracking.
1.Effectively prevents formation of harmful oxides of Aluminium, Manganese or Silicon.
2.Forms a protective cover that minimises oxidation and Zinc fuming.
3.Increases fluidity and feeding properties.
4.Reduces dross formation and crucible build-up.
5.Avoid metal content skimmings.
6.Does not alter alloy compositions
T-Logas (for easy and efficient removal of Hydrogen from all Copper base and Nickel base alloys).
In the production of pressure tight castings to with-stand high pressures, removal of all traces of gas is essential. Degassing treatment is mandatory. When the original charge material contains foreign matter or is having contaminated with grease and oil, Logas removes dissolved gases and suspended impurities in one operation.
1.Eliminates gas porosity and casting leakage under pressure.
2.Ensures homogenous alloy with improved mechanical properties
3.Promotes better feeding of castings
De-oxidising Tubes (For controlled de-oxidation and increased fluidity of copper and nickel alloys)
Different alloys require different De-oxidiants. De-oxidising tubes are available in different grades containing the appropriate De-oxidents like Phosphor cooper, Calcium Boride, Bron Managanes and Magnesium in proper quantities. Ingredients are in fine granular form and most effective remover of oxygen and oxides
1.Provides accurate control of de-oxident.
2.Easy to use.
3.Prevents waste of expensive material.
4.Granular form provides fast and complete removal of oxides and excess oxygen.
5.Prevents porosity and increases fluidity of metal.
6.Sulphur embrittlement is prevented in Nickel Alloys.
7.Ensures production of sound pressure tight castings.
Improval A.C./A.C.2 (For fast and efficient removal of Aluminium from Copper and Nickel Alloys)
Alloys where Aluminium is not an alloying element, Its presence even in traces substantially reduces mechanical properties and causes the castings to leak under pressure. This is because the Aluminium impurity oxidizes readily to form dross and inclusions which locate themselves at the grain boundaries, weakening the structure and causing porosity.
1.Removes Alumlnium and its oxide efficiently.
2.Does not introduce other impurities
3.Assures slag free melt.
4.Forms covering slag that reduces oxidisation losses and increases fluidity
Metal Cleaner (Standard) or Cleanex Block A
Alloys poured without covering fluxes show abnormal high metal content in dross and often required the addition of alloying elements
1.Oxidation and fuming of Zinc restricted.
2.Prevent absorption of harmful gases.
3.Minimum melting loss and clean alloy with no slag inclusion.
4.Slag is free from trace of metal.

Powder coatings must be made into a paste prior to application. After as 24hr. bulge they may be used in the necessary viscosity. Application of two thin layers instead of one thick layer is recommended. Alcohol based coatings should be used for mould & cores containing P.F. resin alkyd base and Co2 cured binder.
