As one of the leading cut wire abrasive manufacturer, Spajic company in its offer has a wide range of diameters, hardness and materials of abrasives, that have found their use in surface treatment processes in different industries. By cutting the wire to the length equal to the diameter of the wire, cylindrical cut wire abrasives are produced. By rounding cylindrical abrasives, conditioned cut wire abrasives are produced. We can distinguish three types of conditioned abrasives based on the degree of rounding G1, G2 and G3 type. Based on the type of industry and surface treatment application, the type of cut wire abrasives is determined (cylindrical or conditioned), material that the abrasives are made from as well as their hardness.


By cutting the wire to the length equal to the diameter of the wire, Spajic company produces cylindrical cut wire abrasives. The type of wire that will be used is related to the industry where the abrasives are used, as well as to the material that is being treated by those cut wire abrasives. Regarding that, we can use steel wire, aluminum, galvanized, brass as well as stainless steel wire.

Shape (cylindrical shape with sharp edges) determines that this type of cut wire abrasive should be used for cleaning, rust removal, paint and color removal, grease removal, but as well in the sanding process (in foundries) for removal of the excess material from cast parts.

One of the main characteristics of this abrasive is its long-term use. In the process, cylindrical cut wire abrasives are becoming rounded. That makes a larger number of uses available and extends the service life of the cut wire abrasives.

Spajic company, in its cylindrical cut wire abrasives program, manufactures abrasives ranging from 0.4mm to 2.5mm in diameter while respecting the standards DIN 8201-4; SAE J-441


In the process of rounding of cylindrical cut wire abrasives, conditioned cut wire abrasives are made.

Depending on the degree of rounding we have three different types of conditioned abrasives: G1, G2 and G3. With different needs in different industries, different types of conditioned cut wire abrasives are used. Also, the materials of the wire used, differ depending on the specific needs of the industry or the surface treatment itself (steel, stainless steel, aluminum).

Conditioned cut wire abrasives have found their use in shot peening process. This process is widely used in aero and auto industries. The shot peening process uses conditioned cut wire abrasives because of their spherical shape. The shape of conditioned cut wire abrasives doesn’t damage the surface of the material that is being treated, but results in the increase of hardness of the treated material or part, as well as in increase of its wear resistance.

Conditioned cut wire abrasives that company Spajic produces are distinguished, among other things by durability, large number of possible reuses (long service life) and quality finish of the treated material.

In its production range of conditioned cut wire abrasives, Spajic company produces a range of diameters – from 0.4mm to 1.6mm, while fulfilling the standards  VDFI 8001; SAE J-441; AMS 2431/8A



Taking into account the microstructure of the cut wire abrasives, which is perlitic, without internal defects (cavities, cracks, porosities), they last longer, have greater service life than other metal abrasives that are used (for example cast shots). Hence, cut wire abrasives made by Spajic company can have the service life of cca 4000 cycles.

Cut wire abrasives have a high level of consistency in terms of shape and hardness which directly influences the increase of quality of the surface treatment of the materials being treated.

Taking into account large number of possible reuses, cut wire abrasives last longer, thus saving on ordering and purchasing another quantity of some other abrasives is obvious. As by using the cut wire abrasives, the treated material is not damaged, or it has no oxide residue left on it, there are no additional costs for after treatment of the materials. The compact microstructure prevents breaking of abrasives and damaging of the treated material, so saving money for eventual additional treatment of the damaged part is present. Less dust is made by using cut wire abrasives, so, as an addition to a healthier working environment, saving are made in the purchase of dust collectors.

The perlitic microstructure of the cut wire abrasives results in break resistance. While in the process of shot peening/shot blasting, for example, conditional cut wire abrasives do not break. This prevents damaging of the treated surface by the sharp edges that are formed when other types of abrasives break. The fact that the particles of our cut wire abrasives do not break, result in the longer lasting of the operational mix used for treatment. Not breaking also reduces the forming of dust and results in a safer working environment. That is not the case when using cast shots.
