Diamond segment is the function part of the diamond saw blade. Diamond segment is made of diamond and metal material bond. Diamond is a kind of super hard material, which can work as a cutting edge. The metal material bond, usually made of metal powder or metal alloy powder, is used to fix the diamond. Different composition makes formula.
Formula is not fixed, subject to hardness and abrasiveness of the cutting material.If the cutting material is hard, the metal material bond of the diamond segments should be softer. That is because diamond will get blunt faster when cutting hard material, and softer bond can wear with diamond faster, and then new diamond will be exposed earlier to ensure the smooth cutting. While, if the cutting material is not so hard, the bond then need to be harder. That is because diamond last longer for soft cutting matertial, and harder bond can make sure the new diamond will not be exposed to work so early, so longer lifespan for the segment.
