Specific Gravity Of General Materials Table

Aug 12, 2011· This table is a data information resource for the specific gravity of many common general materials. While the data is extremely useful for design, actual individual samples will probably differ. Temperature and purity will often have a definite effect. As 1000kg of pure water @ 4°C = 1 cubic meter, those materials under 1000kg per cubic meter ...
