1. Not deformed, high hardness, strong wear resistance. The rocks are long natural aging, the organization structure is uniform, the linear expansion coefficient is minimal, the internal stress disappears completely, does not deform. Not afraid of acid, alkali material erosion, will not rust, do not have to paint oil, not easy to sticky dust, maintenance, easy maintenance, long service life.
2. Abrasion resistance, high temperature, maintenance-free. Good rigidity, high hardness, strong abrasion resistance and small temperature deformation. There will be no scratches, no constant temperature to prevent, at ambient temperature can also maintain its original physical properties.
3. Physical stability, organization meticulous, affected by the impact of grain falling off, the surface can not afford burrs, does not affect its plane precision, material stability, to ensure long-term non-deformation, linear expansion coefficient small, high mechanical precision, anti-rust, magnetic, insulation. No magnetization, the measurement can smooth movement, no creaky sense, not affected by damp, plane said fixed.
4. But with certain radioactivity, it is not recommended to use large areas.
