Diamond segments of granite saw blade:
Diamond segments of the saw blade have a certain hardness, wear resistance, and toughness. There are 4 carcass materials: copper base, cobalt base, iron base, and tungsten carbide base. Among them, cobalt-based carcass material works best, but it is expensive and cannot be widely used. Iron-based carcass material is used mostly in actual production.
In order to enhance the hardness and wear resistance of the carcass, add high melting point materials such as tungsten, tungsten carbide into the composition, and choose low melting point metal such as copper-based alloy such as cobalt, nickel, or manganese as the bonding material of the diamond.
