FEPA F120-220 white fused alumina grit

White fused alumina FEPA F120-220 Grit is a high-purity, low-sodium α-alumina grain that is melted and crystallized with industrial alumina powder at high temperatures and then crushed. It is a particle with closely controlled particle size distribution and uniform appearance. Performance: white, α crystals over 99%, high purity, high hardness. Strong cutting force and good chemical stability. The European FEPA (Federation of European Producers of Abrasives) is an applied particle size specification for abrasives and refractory materials. The particle size numbers are: F120, F150, F180, F220, F220.

Introduce of FEPA F120-220 white fused alumina grit:

White fused alumina is an aluminium oxide material created using the same process as brown fused alumina, except that higher purity alumina is used in the composition. The final product is a purer aluminium oxide used in a speciality process. White aluminium oxide contains virtually no iron content making it a safe material for applications that require minimal foreign contamination.

White Fused Alumina(FAQ)

What is mohs hardness?

Mohs hardness (according to Friedrich Mohs, 1773 – 1839) ascribes a relative hardness value to certain known minerals on a scale ranging from 1 (talc) to 10 (diamond). Accordingly, a mineral is considered harder than another if it can scratch the latter. Please note that these values merely form an

What is the grit type?

Grit type is either aluminum oxide (white, pink, ruby red, brown, grey, etc.) silicon carbide (black or green), ceramic (blue and pink) or any combination of these. Grit types are sometimes mixed in combination for achieving certain cutting characteristics.  Aluminum oxide is friable (white) or semi-friable (pink, brown and grey, red,

What is the d50 value?

The d50 indicates the mean particle size. d50 means that 50% of particles fall within the specified grain size.
