The most important characteristic for the quality of brush wire is the tensile strength,which determines the abrasion-proof,hardness and cutting duty of the wire brush,The list beside details the wires that are more frequently used today and the table above details the chemical and physical qualities.The indications of the tensile strength refer to a medium wire diameter of 0.3mm.In order to obtain our worle renowned wire quality,we are always in touch with internationally chosen wire manufacturers and thus are in the position to offer you a wide variety of wire qualities for all types of applications.
Surface speed is a decisive factor in achieving optimum performance from a brush.Please choose the appropriate surface speed on the basis of the materials of the surface,required effects and the power applid.As a general guide,we recommend the following surface speeds when working on the materials listed.Please note: the operating speed should never exceed the maximum RPM ratings for each brush as shown in this catalogue.

As-is round filament with integrated silicon carbide(S I C) grit is used worldwide,We offer grit sizes from 46 to 800,heat stability,a considerable chemical resistance and even grit insertion.
Our basic quality is principally composed of heat resistant basic Nylon material (including all types from Pa6 up to PA 6.12)and a grit percentage of 20 to 40.
Abrasive filaments are especially appropriate for deburring processes and surface treatment of steel, heavy metals,aluminum and even wood.
