What Is The Hardness of Granite Surface Plate?

Oct 24, 2016

Granite surface plate is made of granite materials, these granite materials undergo rigorous physical tests, fine crystal, hard texture, compressive strength of 2290-3750 kg / square centimeter, the hardness of Mohs hardness 6-7.

Granite slabs are extremely resistant to wear, acid, alkali, a high corrosion resistance, hand-lapping made, never rust. Granite belongs to non-metallic materials, no magnetic reaction, no plastic deformation. Its hardness is 2-3 times higher than that of cast iron (equivalent to HRC> 51), so the precision is good.
