Alumina ceramics have many excellent properties, so they are widely used in the world. Alumina ceramics have a Vickers hardness of 15GPa, a density of about 3.75g/cm3, a compressive strength of about 2100MPa, a flexural strength of 300Mpa, a volume resistance of 1014Ω·m, an expansion coefficient similar to that of metals, and good chemical stability.
The positioning pin is based on the workpiece hole as the positioning reference and participates in the part that limits the freedom of the object. The process of determining the correct position of a part in a fixture is usually called positioning. The positioning pin is required to completely enter the positioning hole when positioning.
