Appearance: Dark gray powder
Character: The particles are multi-angle smooth particles. The micros structure, more than 80%, is homogeneous, dense and dendritic particles.
Applications: Widely used for exploiting drill bits, PCD drill and other melt-penetration products. Also used for hard facing of steel-tooth drill bits, food/vegetable oil machineries and motors.
