ELIDRON 199 – DEGASSING TREATMENTS OF ALL ALUMINIUM ALLOYS
Elidron 199 degassing tablets are recommended for: washing the bath with nitrogen, removing suspended oxides, eliminating the gas trapped with them and eliminating the hydrogen contained in the bath.
Elidron 199 tablets have a dual effect. The tablet, due to the heat of the bath, decomposes, releasing nitrogen gas capable of bringing the dissolved hydrogen and oxides suspended in the bath to the surface. The salts contained in the product are capable of reacting with the oxides and performing excellent metal purification. Elidron 199 is recommended for the washing, degassing and deoxidation treatments of all aluminum alloys except those containing Magnesium in quantities greater than 3% or hypereutectic alloys. The tablets can be used in crucible, reverberatory or ladle furnaces.
