Granite bench, marble bench material characteristics and advantages:
1. No distortion, high hardness, wear resistance.
2. Anti-abrasion, high temperature, maintenance-free.
3. It can ensure long-term deformation, linear expansion coefficient, high mechanical precision, rust, anti-magnetic, insulation.
The advantages of Granite bench, marble bench:
1. A rock through a long-term natural aging, homogeneous structure, linear expansion coefficient is extremely small, internal stress completely disappeared, no deformation.
2. High hardness, wear resistance, temperature deformation.
3. Not afraid of acid, will not rust, do not oiled, easy to clean dust, convenient and simple to maintain, long service life.
4. Without constant temperature to prevent, at room temperature can be maintained temperature volume accuracy.
5. Do not magnetization measurements can move smoothly, no tight feeling, not damp the impact, the plane weighed good.
Granite physical properties:
Proportion: 2970-3070kg / m3
Compressive strength of 245-254N / m
Water absorption: 0.13%
Shore Strength: Hs70 more
