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, … Meer weergeven 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 Meer weergeven Fluxes have several important properties: • Activity – the ability to dissolve existing oxides on the metal surface and promote wetting with … Meer weergeven Fluxes for metal joining The composition of fluxes is tailored for the required properties - the base metals and their surface preparation (which determine … Meer weergeven 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 … Meer weergeven 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 … Meer weergeven The terms resin flux and rosin flux are ambiguous and somewhat interchangeable, with different vendors using different assignments. Generally, fluxes are … Meer weergeven During the submerged arc welding process, not all flux turns into slag. Depending on the welding process, 50% to 90% of the flux can be reused. Meer weergeven Web1 Fluxes are raw materials, such as limestone, dolomite, lime and silica sand, which are used to reduce the heat or other energy requirements of thermal processing of minerals … WebThis versatility of iron-carbon alloys leads to their widespread use in engineering and explains why iron is by far the most important of all the industrial metals. History There is evidence that meteorites were used as a source of iron before 3000 bc, but extraction of the metal from ores dates from about 2000 bc. list of verbs and their forms
