THE PRODUCT :
The melting of Copper and Copper-based alloys is a critical process. Molten Copper dissolves both Oxygen and Hydrogen. On solidification Oxygen And Hydrogen can combine to form water vapour which causes porosity In the casting. Without the presence of Oxygen, Hydrogen alone may also cause gas porosity. Alloys containing aluminium form oxide skin, which can cause problems in castings.

RECOMMENDED :
The Copper and Copper alloys containing aluminium oxidizes during melting, forming a skin of oxide which results in sluggish pouring. CERAFLUX-AB2 is recommended to eliminate sluggish pouring. CERAFLUX-AB2 flux range contains chemicals that dissolve alumina, removing it from the melt by floatation. The surface layer formed is a liquid slag, from an efficiency aspect, a liquid slag performs best. CERAFLUX-AB2 forms liquid slag for efficientness.

APPLICATION :
Pre-heat the crucible or furnace. Charge ingots and scrap and commence melting. When part of the charge becomes pasty, sprinkle CERAFLUX-AB2 flux (1kg for 100kg of metal) over the surface.
Continue charging and melt under the protective cover of CERAFLUX-AB2 as rapidly as possible. When the metal is at pouring temperature, add a further quantity of CERAFLUX - AB2 flux (0.5kg for 100kg of metal) and with a perforated saucer plunger plunge the flux to the bottom of the melt then with a rotary movement of the plunger, “wash” the flux in bringing it into intimate contact with all parts of the melt in order to cleanse it of alumina particles. After 2-3 minutes withdraw the plunger and allow the melt to settle.
Deoxidize by plunging “E”type deoxidizing tube to collect suspended non-metallic impurities and increase the fluidity.
