About Abrasive Filament

DAMI abrasive filaments are produced by loading abrasive grits such as silicon carbide (SIC) or aluminum oxide (AO), Diamond evenly into high-quality nylon and extruding the mixture into filaments.
DAMI abrasive filaments have superior stiffness, good flexibility, and great elasticity. Brushes made with DAMI abrasive filaments are highly efficient in grinding, finishing, polishing, and deburring in different industries and for different surfaces e.g. curved, concave, convex surfaces or insides of pipes without damaging the dimensions and fineness of the workpiece.
Diamond (DM)
 Diamond is the hardest substance found in nature with sharp cutting edges and corners, superior self-sharpening property, and high toughness. The grinding ability is 4 times better than SIC and 10 times better than AO. Due to its expensive price, DM abrasive filament has only been used for super hard material and industry with high added value: such as wolfram steel, silicon plate, expensive jewels.



PROPERTY COMPARISON OF GRIT

- Vickers hardness (HV): DM > GC > SIC > WA > AO
- Cutting force: DM > GC > SIC > WA > AO

THE BEST ONE IS THE MOST SUITABLE ONE

The most popular abrasive filaments are SIC and AO filaments. SIC abrasive is generally the best choice for the most of the applications. AO is suitable for precision polishing and soft surface. Basically, every industry has its own common-used abrasive filament. For detailed questions, please do not hesitate to contact us for consulting. It would be more helpful, if you can send us some samples for analyzing.
