undeformed

After a long time of natural aging, the structure of the rock is uniform, the linear expansion coefficient is very small, the internal stress completely disappeared, no deformation.

High hardness

Good rigidity, high hardness, strong wear resistance, small temperature deformation.

Long service life

No need to grease, not easy to stick dust, maintenance, maintenance is convenient and simple, long service life.

There will be no scratches, not blocked by constant temperature conditions, at room temperature can also maintain its original physical properties.

unmagnetized

The measurement can move smoothly, no stagnation feeling, not affected by moisture, the plane is set. Physical properties: specific gravity 2970-3070kg/m³; Compressive strength: 2500-2600kg/cm²; Elasticity coefficient: 1.3-1.5×106kg/cm² Water absorption.
