RUTILE KFR90 - min.93% (up to 300 microns)
Used for the production of coatings (coatings) of welding electrodes for manual arc welding, providing excellent arc control, weld toughness and strength, and easy removal of welding slag (by making it porous). It is also used as an additive to increase strength in metal alloys and as a stabilizing component in high-temperature firing in ceramics.
