Our granite measuring devices and granite mechanical components are made of high quality "Jinanqing"granite due to their high precision ,long duration,good stability and corrosion resistance ,they have been more and more used in product inspection of modern industries. and such high-tech areas as mechanical caerospace and scientific researches.
Physical Properties of "JI Nan Black"Granite Rock:Specific Gravity :2970-3070kg/m3Compressive Strength :245-254N/mm2Elastic Modulus;1.27-1.47N/mm2Linear Expansion Coefficient:4.61*10-6/cWater Absorptivity :<0.13%Shore Hardness:above Hs70 Granite measuring tools have the following characteristics: 1.High precision reliable stability resistant to deform and guaranteed accuracy under normal ambient temperature.2.No-rust and anticorrosion.
3.Wear resistance long service life.
4.Any working surface cutting or scratching does not bring about rough "edges" which might influence its measuring precision.
5.Nonmagnetization.
6.Gloosy surface without sluggishness when the workpieces or tools are moving on it.
