The capacity of resisting a hard object pressed into its surface is called as hardness in physics. And tungsten copper rod hardness is the basic indicator to evaluate the materials if soft or hard. More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html Tungsten copper rod hardness can be divided into scratch hardness, indentation hardness and rebound hardness. Scratch hardness: Mainly used to compare the hardness of minerals, the method is selected from the soft end of a hard rod…

The mass of some substance per unit volume is called density of this material, which is a reflection of the physical properties of the material in physics. Tungsten copper rod density is a kind of feature itself, which does not change with mass or volume.
