Flux chemical
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. Some of the earliest known fluxes were sodium carbonate, potash, charcoal, coke, borax, lime, … 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 See more Fluxes have several important properties: • Activity – the ability to dissolve existing oxides on the metal surface and promote wetting with solder. … See more Fluxes for metal joining The composition of fluxes is tailored for the required properties - the base metals and their surface … See more Fluxes for soldering certain metals Some materials are very difficult to solder. In some cases special fluxes have to be employed. Aluminum and its alloys Aluminium and its alloys are difficult to solder due to the … 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 effects • Interference with test equipment, which is due to the insulating residues … See more The terms resin flux and rosin flux are ambiguous and somewhat interchangeable, with different vendors using different … See more During the submerged arc welding process, not all flux turns into slag.
