Ready mixed bonds for wire saws

A good bonding of the matrix powder to the metal carrier is one of the major pre-conditions for a good wire saw. In case of hot pressed beads this is achieved by the pressure applied during the sintering process. By specific additives in the matrix a self-brazing effect is initiated during sintering. We offer suitable bonds for all processes and on request we also assist to procure the needed carriers and infiltrates.

In the free sintering process the bonding is achieved by an infiltrate added during a second run through the oven. A new powder generation, however, achieves good bonding also in free sintering in just one run through the sintering oven.
