Features:

1. No deformation, high hardness, wear resistance.

2. Anti-abrasion, high temperature, maintenance-free.

3. Physical stability, careful organization, by the impact off the grain surface can not afford to flash, does not affect the accuracy of their plane, the material is stable and can ensure long-term deformation, linear expansion coefficient, mechanical precision, anti-rust, anti-magnetic, insulating .

Advantages:

A rock by the long-term natural aging, organizational structure is even a very small linear expansion coefficient, internal stress disappear, not deformed.

Second, rigid, high hardness, wear resistance, and temperature of deformation.

Third, not afraid of acid, alkaline liquid material erosion, will not rust, do not coated with oil, easy to stick dust, maintenance, easy and convenient, long service life.

Fourth, will not scratch, without a constant temperature to prevent, at room temperature, can maintain its original physical properties.

Fifth, do not magnetization measurements can move smoothly, without Zhise sense, free from damp impact, the plane that set good. Physical properties: the proportion of 2970-3070kg/m3 compressive strength :2500-2600kg / cm3 elasticity :1.3-1 .5 � 106kg/cm2 water absorption.
