An abrasive article with abrasive grain such as corundum, a binder which is a hardenable organic or inorganic system, for example plastic, such as phenol resin, and grinding-active fillers, as well as an abrasive with abrasive grain such as corundum, a binder which is a hardenable organic or inorganic system, for example plastic, such as phenol resin, and grinding-active fillers. The abrasive compound of the abrasive consisting of abrasive grain, binder and the fillers is placed on a flexible substrate, which is formed by a nonwoven fabric. New low-priced fillers with low toxicity are incorporated in the abrasive article and, in fact, metal complex salts with the following structure: EQU uM.sub.1 .multidot.vM.sub.2 .multidot.wHal.multidot.xChal.multidot.zPh where: PA0 M.sub.1 =pure metal or mixture of alkali metal, alkaline earth metal and/or Al PA1 M.sub.2 =pure metal or mixture of Zn, Mn, Fe except for Fe as chloride PA0 Hal=pure halogen or mixture of F, Cl, Br, I PA0 Chal=chalcogenides, O and/or S PA0 Ph=phosphate or more highly condensed phosphates P.sub.r O.sub.s (r=1 to 10, preferably 1 to 2, PA0 s=4 to 20, preferably 4 to 7) u, v, w, x or z=0 to 95%, and the total of u and v…
