ALUXAL 267 – Flux for Sodium Addition

Aluxal 267 is a high quality flux, in powder form, for sodium addition into Al-Si alloys with silicon content ranging between 7-13%. Modification treatment alters the silicon structure of the alloy and improves castings mechanical properties. The silicon structure changes from coarse, angular, acicular crystals into fine, rounded, interconnected fibrous particles, perfectly distributed in the aluminium matrix. The main advantage is a considerable improvement of tensile strength and elongation characteristics.

ALUXAL 267 is recommended for the modification treatments of Al-Si alloys casted at temperatures between 750-780°C.
