We are a manufacturing and trading combo,produce and export fused alumina for more than 10 years.

Raw materials containing aluminium oxide are electrothermally melted at a reaction temperature of more than 2,000 °C to produce the various fused aluminas. Different starting materials are used depending on the desired type of fused alumina. For instance,

Dynamic image analysis (DIA) Static light scattering (SLS, also called laser diffraction) Screen analysis Impedance method Sedimentation

Grit size typically runs from coarse (16 -24 grit), medium (36 – 60 grit) and fine (80-120 grit).  Superfine grits run from 150 and higher.  Grinding wheels usually will be between 24 and 100 grit.  Honing stones and

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

Abrasive grains – usually aluminum oxide or silicon carbide Bonding agent – usually a resin bond Spacing of grains within the bond – determine porosity and strength

MicroBlasting is extremely efficient and precise, so it is hardly likely you will need to recycle abrasive, but it is important to know the risk involved. Unlike grit or bead blasting, a MicroBlasting system can only cycle abrasive

Glue – A system where both coats are made of animal glue is used when the strength of the bond is not an important factor, such as with lightweight papers and materials. Phenolic Resin – This system uses

The description of the grain shape can range from “angular” to “acicular” to “spherical”. When the value of the dimensionless form factor is 1, the grain is spherical. The smaller the form factor, the pointier the grain.

An abrasive’s shape, hardness, and particle size really determine the effectiveness of a MicroBlasting application. Each application is unique, and abrasive selection depends on the composition of the targeted part and the application’s desired result. See our Abrasive Media

This is a hard question to answer in a short space.  While the markings mean the wheels should perform the same, differences in factory equipment and marking systems may make one product behave differently than another.  They should

The specific surface means the outer surface of a substance including all accessible pores in relation to the mass. It is determined using the Brunauer-Emmett-Teller (BET) method.

Corundum is the most frequently used abrasive. The purer the corundum, the harder it also is, which can be determined from the colour. The toughness can be increased by adding various metal oxides and by shortening the cooling

Our main market include Europe,America,Oceania,Asia.,etc.

Silicon carbide (SiC) is produced from coke and quartz sand applying the Acheson process in an electric resistance furnace. When petrol coke and quartz sand are grouped around a graphite electrode and heated to a temperature of 2,000°C,
