Carbide Cutting Tools---105×9.0×7.5
Little knowledge of cemented carbide
Density: The mass per unit volume, generally decreases with the increase in the proportion of the binder phase
Hardness: The ability of a material to resist elastic deformation, plastic deformation, or failure. Generally, it decreases with the increase of the bonding phase ratio.
Flexural strength: the ability of a material to resist bending without breaking
Fracture Toughness: The ability of a material to resist the unstable growth of cracks
