Aluminum Cleaning Agent ARSAL 2125

Cleaning flux Arsal 2125 is a kind of highly compacted cleaning and skimming granules for all hypoeutectic and eutectic aluminums, wrought and casting alloys such as e. g.: G-AlSi10Mg, G-AlSi7Mg, G-AlSi8Cu3, G-AlSi12 and G-AlZn10Si8.

Application Range:

ARSAL 2125 stand out by good storage stability and is applicable within a wide reaction range, it can be used in the lower temperature range (from 700°) of the aluminum melt. It is applicable for all aluminums, wrought and casting alloys which may contain small quantities of sodium (<10 ppm).

Quality Characteristics:

• removes oxides from the melt by flotation and reduces the hydrogen content

• forms mixing phases with the oxides and adheres to the oxide by energetically low surface tension

• prevents the formation of corundum and its adherences

• produces a fine, powdery and low-metal dross

• works in all types of furnaces and crucibles

• permits the easy removal of adherences

• is of very low smoke and odor emission

Addition Ration:

Depending on the level of impurities, from 0.05 to 0.25% by melting weight

Product Application:

Cleaning flux ARSAL 2125 works in melting, holding and pouring furnaces as well as in crucibles. When using as cleansing agent, submerge the required amount cleaning flux Arsal 2125  into the melt (during the impeller treatment or when decanting). Gently stir with a well pre-heated and coated tool until a fully reacted dross forms and then skim it off.

For the dross treatment, distribute ARSAL 2125 on the surface and stir the agent in the dross with a tool. Skim it off after a reaction time of three minutes. When it is used regularly (one to two times per shift) it impedes the formation of built-ups on the furnace walls and crucibles.

During the impeller treatment oxides are bound and the share of metal in the dross is reduced essentially. Thus, more metal is available for the casting process (metal saving potential). The addition of the agent in the pouring stream while decanting increases this effect.

Typical Properties:

Appearance: blue granules

Odour: odourless

Reaction temperature: from approximately 700°C (higher temperatures accelerate the reaction)

Packaging:

25 kg bags, 3-fold with plastics lining, special packaging such as 1000kg big bag packing also available.

Storage and Shelf Life:

Store in a cool place (below 32°C/90°F); keep container dry and tightly closed. The shelf life is at least 6 months if properly stored.
