Abstract (en)
[origin: WO2007146161A1] The present invention relates to compositions and processes for the production of high-aluminum alloy. More specifically the patent relates to compositions and processes for the production of high-aluminum alloy for general galvanizing of ferrous materials. In one embodiment, the present invention relates to a unique combination of a zinc-ammonium flux and a molten zinc-aluminum alloy bath containing silicon. The present invention also relates to an improvement in the fluxing step used in the galvanizing process for iron and steel, and high aluminum-content steel made using that improved process.
