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 ordinal scale: A higher value means greater hardness, but the distances between the scale values are not always the same.
A Mohs hardness of 10 is assigned to diamond, the hardest material. A diamond therefore can only be cut using another diamond.
Diamonds are closely followed by the corundum group, which includes rubies and sapphires.
Mohs hardness – a scale ranging from 1 to 10

Is sample parts testing available?

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

What does the form factor (grain shape) indicate?

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.

Form and shape of the abrasive:

This decision is made by determining how the abrasive will be used by the individual. Abrasives are sold in forms such as sheets, large/small discs, belts, and large/small rolls. Selecting the right form is determined by whether the

Type of glue required:

This decision is made by the type of abrasive you have selected or the type of process you will be performing. Glue – A straight animal hide glue that is used to adhere the abrasive particles to the

How is fused alumina obtained?

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,

What is silicon carbide?

Silicon carbide is a chemical compound of silicon and carbon and belongs to the group of carbides. The chemical formula is SiC.Silicon carbide is at the same time the hardest and lightest ceramic material and is also highly

What is your sample policy?

We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost. 

What is the shelf life of fused aluminum oxide?

fused aluminum oxide products do not have a known shelf life. As long as the product is maintained in the original sealed container and stored in a cool, dry, ventilated area, our product will last indefinitely

What is the d50 value?

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

What is the best way to store my abrasives?

The best way to have abrasive products retain maximum performance and work life is to store them properly. The bonding and backing materials used in abrasives are very sensitive to changes in temperature and humidity. Abrasives are best

What is the specification?

A typical grinding wheel specification consists of the grit type, the grit size, the hardness, the structure and the bond.  A typical grinding wheel specification would be A60-I10-VS.  ‘A’ is the grit type (aluminum oxide), ’60’ is the

What is a silane coating used for?

When functionalising fused alumina, a very thin layer of a silane adsorption group is applied to the fused alumina particles. This organic surface coating has the effect of better embedding and increased scratch resistance in a melamine resin
