Sagwell’s pre-alloyed powders, composed of Fe, Cu, Ni and W, lay the technological foundation for high-performance diamond tool alternatives, solving the inherent flaws of single-element mixed powders.
Their key advantages in diamond tools are as follows:
1. Exceptional compositional uniformity: Each particle has a fixed proportion of Fe, Cu, Ni and W, avoiding sintering segregation and uneven liquid phase, ensuring a consistent microenvironment around each diamond.
2. Enhanced sintering activity: Pre-bonded atoms shorten diffusion paths, enabling high densification (high flexural strength) at 800-850℃ in less time and overcoming the sintering difficulty of single-element Fe and W.
3. Predictable stable performance: Superior batch consistency vs mechanical mixed powders supports reliable data (sharpness 85-95%, service life 70-90%).
What key properties and mechanisms enable this powder to replace cobalt in diamond tools?
Sagwell’s technicians highlight three points:
1. High holding force (replacing cobalt’s wettability)
2. High strength and toughness (replacing cobalt’s solid solution strengthening)
3. Controllable wear and sharpness
The ultra-fine iron-copper-nickel-tungsten pre-alloyed powder developed by Sagwell can realize "cobalt substitution" in the diamond tool industry. This substitution is not a simple replacement of cobalt in the matrix, but rather a formulation adjustment centered on this powder.
