Fluxes for aluminum alloys are generally composed of chlorides and fluorides of alkali metals and alkaline earth metals, and their main components are KCl, NaCl, CaF, Na3 AlF6, Na2 SiF6, etc. The physical and chemical properties of the flux (melting point, density, viscosity, volatility, hygroscopicity, and interface with oxides) play a decisive role in the […]
