Fluxes are also used in foundries for removing impurities from molten nonferrous metals such as aluminium, or for adding desirable trace elements such as titanium . As cleaning agents, fluxes facilitate soldering, brazing, and welding by removing oxidation from the metals to be joined. See more In metallurgy, a flux (from Latin fluxus 'flow') is a chemical cleaning agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining See more Fluxes have several serious drawbacks: • Corrosivity, which is mostly due to the aggressive compounds of the activators; hygroscopic properties of the flux residues may aggravate the … See more Fluxes for metal joining The composition of fluxes is tailored for the required properties - the base metals and their surface … See more The terms resin flux and rosin flux are ambiguous and somewhat interchangeable, with different vendors using different assignments. Generally, fluxes are labeled as rosin if the vehicle they are based on is primarily natural rosin. Some … See more Metal joining In high-temperature metal joining processes (welding, brazing and soldering), flux is a substance that is nearly inert at room temperature, but which becomes strongly reducing at elevated temperatures, preventing … See more 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 … See more Fluxes for soldering certain metals Some materials are very difficult to solder.
