Four characteristics of marble

Four characteristics of marble: 

1. No deformation

After long-term natural aging, marble has a uniform structure, a very small linear expansion coefficient, and the internal stress completely disappears without deformation.

2. High hardness

Marble has good rigidity, high hardness, strong wear resistance, and low temperature deformation.

3. Long service life

No need to apply oil, not easy to stick to dust, easy and simple maintenance, and long service life. There will be no scratches, it is not blocked by constant temperature conditions, and the original physical properties of marble can be maintained at room temperature.

4. Not magnetized

It can move smoothly during measurement, without a sense of stagnation, and is not affected by moisture. The plane is weighed well. The physical properties of marble: specific gravity 2970-3070kg/m3; marble compressive strength: 2500-2600kg/cm2; elasticity coefficient: 1.3-1.5×106kg/cm2 water absorption.
