Product features of White fused alumina 0-1mm 1-3mm 3-5mm 5-8mm
High hardness: Mohs hardness is 9.0, Vikers hardness(HV) is 2000-2200.
High toughness: Take WFA F120 for example, the compressive strength of white fused alumina is 100KN/cm2.
High density: The volume density of WFA is 3.6g/cm3.
High temperature resistance with low thermal conductivity and low coefficient of linear expansion. So it can resist to thermal shock.
PH value: White fused alumina is an neutral substance with PH Value 7.0-8.0.
High resistance to chemical corrosion.White fused alumina is resistant to most acid and alkali material.
