Fluxing treatment

Fluxes have several important properties: • Activity – the ability to dissolve existing oxides on the metal surface and promote wetting with solder. Highly active fluxes are often acidic or corrosive in nature. • Corrosivity – the promotion of corrosion by the flux and its residues. Most active fluxes tend to be corrosive at room temperatures and require careful removal. As activity and corrosivity are linked, the preparation … WebJul 28, 2012 · Degassing by fluxes. Fluxes composed of chlorine and fluorine containing salts are used for degassing molten aluminum alloys. Degassing fluxes are commonly shaped in form of tablets.
