ALUXAL 203 SS FPS – Flux for Aluminium Alloys

ALUXAL 203 SS F.P.S. is flux studied for covering and drossing-off treatments of aluminium alloys. The flux creates a physical barrier between molten aluminium and furnace atmosphere during the melting. The product reduces oxides inclusion and allows the production of high quality casting. The dross produced during the exothermic reaction is dry and very low in metal content. ALUXAL 203 SS F.P.S. is sodium free.

It is recommended for the following alloys:

  • Al-Mg 3-10%
  • Al-Si premodified with strontium
  • Hypereutectic Al-Si treated with phosphorus
  • Al-Si refined with antimony

Packaging and storage

25 kg paper bag laminated with polythene, moisture resistant, heat sealed at the base.

Warnings: The product is hygroscopic: Store in a dry storage and close the package after each use. If the product is stored in a dry place away from sunlight, the product does not expire.
