Germinal 1604

Germinal 1604 is a high yield grain refining flux in tablet form. It is sodium free and contains high quantity of Titanium and Boron to allow a fine grain formation in the structure of Aluminium-Magnesium alloys. The product doesn’t have degassing action, therefore it is advisable to use degassing flux after the treatment with Germinal 1604 (see our Elidron 208). The degasser will help the distribution of crystallisation nuclei and reduce possible internal porosity. The product is normally used for Aluminium-Magnesium (Mg >3%) and Aluminium-Strontium pre-modified alloys.
