NAPAL 700 R – Modifying Flux in Tablet

Napal 700 R is a modifying flux in tablet form used to add the necessary quantity of Sodium. The addition of Sodium induces a radical change on the solidification structure, with the disappearance of large crystals of primary Silicon and the modification of acicular into rounded particles, well dispersed in the “alfa” solid structure. The result is proved by the appearance of small, fine, dentrites cells. The consequence is a general improvement of mechanical properties.
