1. Have a good decorative effect, can be used for indoor and outdoor architectural decoration
2. With excellent processing properties: sawing, cutting, polishing, drilling, sculpture and so on. The processing accuracy of up to 0.5μm, luminosity of more than 1600. Can be used for roller skates ground, monuments, monument.
3. Good wear resistance, five to ten times higher than cast iron.
4. Coefficient of thermal expansion is small, not easily deformed, similar to indium steel, minimal impact by temperature.
5. Elastic modulus, higher than cast iron.
6. Good rigidity, large damping coefficient, fifteen times larger than steel. Earthquake-proof
Shanxi black is relatively brittle, when damaged only partially fall off, will not affect the overall flatness.
8. Shanxi black chemical stability, easy to be weathering, acid and alkali and corrosion-resistant gas erosion, the chemical is proportional to the content of silica, the service life of up to 200 years.
9. Shanxi black non-conductive, non-magnetic, stable position.
