Zn AI Master Alloys
Zn Ni Master Alloys
(G5, G10, G15, G20)
Standard Aluminium inclusions in a hot dip galvanizing bath can be successfully adjusted by the use of Master Alloys, to accommodate important variations needed by different processes. It allows for rapid increases in the Aluminium levels without interfering with the coating process or the fundamental bath contents. Produced as a 5, 10, 15 or 20% Aluminium.

Galfan Alloys Galfan 5 – 7 is a galvanizing alloy addition for Steel strip plating plants, in the hot dip galvanizing process. Both the Aluminium and the Mischmetal (Cerium and Lanthanum) are variable to satisfy steel plant individual requirements for their process. Galfan gives the ability to produce coated steel with a thinner, brighter and more corrosive resistance coating that a standard galvanizing process allows. Indicative Chemistry: Aluminium, Cerium and Lanthanum are variable to satisfy individual steel plant requirements Al Ce & La
