Precision Glass Balls 75% SiO2 , 15% NaO2 , 8% CaO2 Density Is 2.8g/Cm3 , Intension Is 700kg/Mm2
Glass Precision Ball
The material of Glass Precision Ball is made up of 75% SiO2, 15% NaO2 and 8% CaO2, Glass Precision Ball is a kind of oxidation combination. Beading has the steady chemistry performance, high intension, anti-wearing, anti-fatigue, anti-canker and so on, whose density is 2.8g/cm3 and intension is 700kg/mm2, but high intension for press.
