Clay sand is sand casting industry according to the original a
modelling with sand, silt content classification in the industry of
clay sand quartz and the content of harmful impurities without
specific request.
For silt content is less than or equal to *0%.
Clay sand is mainly used for cast iron and nonferrous metals
casting with the addition of moulding sand and core sand, to
improve the wet strength, improve the model performance.
