Iron Powder: EHA-T
For Diamond Tools
Standard iron powder for all iron based high-end diamond tools. - Excellent sintering activity and excellent thermal diffusion effect.
- Excellent bonding strength and high deflection. It can increase the holding force of the matrix on the diamond. The three-point bending strength at 750 ℃ exceeds 1200 MPa.
