Granite squares are primarily used to verify the flatness of components. Granite squares are essential instruments for industrial inspection, suitable for the inspection and high-precision measurement of instruments, precision tools, and mechanical components. Primarily composed of granite minerals, including pyroxene, plagioclase, a small amount of olivine, biotite, and trace amounts of magnetite, they are black in color and possess a precise structure. After millions of years of aging, they have a uniform texture, excellent stability, high strength, and high hardness, capable of maintaining high accuracy under heavy loads. They are suitable for industrial production and laboratory measurement work.
Characteristics and Advantages
1. Granite squares have a dense microstructure, a smooth, wear-resistant surface, and a low roughness value.
2. Granite undergoes long-term natural aging, eliminating internal stresses and maintaining a stable material quality that will not deform.
3. They are resistant to acids, alkalis, corrosion, and magnetism.
4. They are moisture-resistant and rust-resistant, making them easy to use and maintain.
5. They have a low linear expansion coefficient and are minimally affected by temperature.
