1> Rebonded or sintered crushed gray/black particles; the bonded particles are spherical or nearly spherical, with good fluidity;
The crushed particles are in irregular shapes.
2> Maximum operating temperature 700°C.
3> High hardness, dense coating, resistant to wear from abrasive particles, fretting wear, adhesive wear, and erosion wear.
4> High fracture toughness.
