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.
