[0002] PCD diamond aluminum alloy saw blades are made from polycrystalline diamond (PCD) material. They are manufactured by welding PCD composite sheets to a carbide or steel blade body. Diamond saw blades are cutting tools widely used in machining hard and brittle materials such as concrete, refractories, stone, and ceramics. Diamond saw blades consist of two main components: the base and the blade head. The base is the primary support for the blade head, while the blade head performs the cutting process. While the blade head is constantly consumed during use, the base does not. The blade head's ability to cut is due to its inclusion of diamond. Diamond, currently the hardest substance, rubs against the material being processed within the blade head. The diamond particles are encased in metal within the blade head.
