Rosin used as flux for soldering A flux pen used for electronics rework Multicore solder containing flux Wire freshly coated with solder, held above molten rosin flux. In metallurgy, a flux is a chemical reducing 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.
Flux describes any effect that appears to pass or travel (whether it actually moves or not) through a surface or substance. Flux is a concept in applied mathematics and vector calculus which has many applications to physics.For transport phenomena, flux is a vector quantity, describing the magnitude and direction of the flow of a substance or property. In vector calculus flux is a scalar ...
The meaning of FLUX is a flowing of fluid from the body. How to use flux in a sentence.

Key learnings: Flux Definition: Flux is defined as any effect that travels through a surface or substance, used in various scientific fields.; Magnetic Flux: Magnetic flux measures the number of magnetic field lines through a surface, with its unit as Weber.; Electric Flux: Electric flux quantifies the electric field lines passing through a surface, measured in voltmeters.
Fluxes designed for specific applications must be capable of handling heat sufficient to join the metal parts. For example, because brazing requires higher temperatures than soldering, brazing fluxes must remain stable and provide oxidation protection at these high temperatures. The table below shows the effects of high temperatures on flux as ...
Flux, in metallurgy, any substance introduced in the smelting of ores to promote fluidity and to remove objectionable impurities in the form of slag. Limestone is commonly used for this purpose in smelting iron ores. Other materials used as fluxes are silica, dolomite, lime, borax, and fluorite. In
Under the head of non-metallic fluxes, he places silica, lime, magnesia, alumina, silicates of lime and alumina, glass, borax, fluor-spar, carbonate of potash, carbonate of soda, niter, common ...
Fluxes refer to the rates at which a quantity, such as mass, energy, or momentum, passes through a specified surface per unit time. In non-equilibrium thermodynamics, fluxes are crucial for understanding how systems evolve over time as they move away from equilibrium, highlighting the flow of energy and matter in processes like heat conduction and diffusion.
