Gauge block provided by our company can be divided to 3 types according to their materials: white steel, tungsten steel, and ceramic. The size of them has a range of 1-100mm. All products with accuracy of 0, 1 and 2 are validated by EISEN standard.
As for the white steel gauge block, the special demagnetizing process can ensure the stability of the dimension accuracy and hardness of HRC62-64.
Material: White Steel
Relative density: 7.8
Expansion coefficient: 11.5
Tungsten steel gauge block is processed by special technology to gain higher hardness of HRA91 and wear resistance. It a product with high precision and little deformation.
Material: Tungsten Steel
Relative density: 15.0
Expansion coefficient: 5.5
The temperature has little influence on ceramic gauge block. Its high wear resistance makes it have longer life (five times of steel material). It can used in precision measurement for a long time even without protection and maintenance because of good corrosion resistance. In the meantime, the special microcrystalline material and high precision surface processing make it stable enough.
Relative density: 6.0
Expansion coefficient: 11
