Physical properties: Grey-brown or grey-black; mohs hardness 5.5 – 6.0; density 4.9 – 5.1 g/ cm3
Physiochemical index: FeCr2O4: first-grade chromite Cr2O3: 38%, second-grade Cr203: 15%
Performance: It has good low-temperature and high-temperature friction-increasing effect, which can obviously improve the friction coefficient stability of the material, as well as reduce abrasion, and improve its heat-fading performance. The more Cr2O3 it contains, the more obvious its friction-increasing effect is.
