Granite main mineral components of pyroxene,plagioclase,minor olivine,biotite,and trace magnetite,black color,brighht and precise structure. After millions of years of aging, uniform texture,with good stability,strength,hardness higher performance. Suitable for heavy load to maintain precision, commonly used in the field of industrial production and laboratory measurements.
