What are the different coated abrasive grain types and their characteristics?

Aluminum Oxide – Aluminum Oxide is brown or reddish in color and a man-made abrasive. It is durable with tough cutting edges. It offers long life and is highly wear resistant even under stress applications. Its applications include aluminum, ferrous metals (including alloy steel), hardwood, and leather.
Crocus – Crocus is reddish brown in color. It is a soft material made from iron oxide. It is the finest natural grain produced. Its applications include cleaning and extremely fine polishing of soft materials such as gold.
Emery – Emery is a dark gray round-shaped natural grain. It is better used as a polishing grain than a cutting grain. It is used for cleaning and polishing metals.
Flint – Flint is a low cost white crystalline nonconductive mineral. It is only available with a paper backing. Its is used for low-pressure hand applications, paint removal, and sanding in the electrical motor industry.
Garnet – Garnet is a reddish brown natural grain. It is relatively sharp and has a medium hardness. Its durability cannot be compared to that of synthetic abrasives. It is used for finishing applications in soft woods such as fir or pine.
Silicon Carbide – Silicon Carbide is black in color. It is a sharp, hard synthetic abrasive. Its friable grains fracture to continually expose new cutting edges and permit fast stock removal. Its applications include aluminum, bronze, non-ferrous metals, and non-metallics such as glass, plastic, rubber and soft woods.
White Aluminum Oxide – White Aluminum Oxide is a friable man-made abrasive. Its sharp, cool cutting edges easily break down under pressure to expose new cutting edges. Its applications include non-ferrous metal finishing and production wood sanding.
Zirconia Alumina – Zirconia Alumina is a bluish gray colored ultra rugged synthetic abrasive. It has large fracture planes and is a sharper, more blocky grain than aluminum oxide. It self-sharpens as it cuts and is available only in coarser grits. It is used for heavy duty grinding on all ferrous and non-ferrous metals, and rough planing of wood products.

What is a mesh vs. Grit size?

If you take a (1) inch space and add wires to it, the number of openings within the 1″ space is defined as mesh. For example, if the 1″ space has ten openings for particles to fall through,

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’s lead time for bulk order?

What is the d50 value?

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

How do i know what abrasive is best for my application?

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

What is the hardness?

Hardness is rated from A-Z with ‘A’ being the weakest bond and ‘Z’ being the strongest.  A weak bond is preferred for grinding harder materials while  a stronger bond is desired for softer materials.  A typical weak bond

Coarseness of the abrasive mineral:

Commonly referred to as “grit”, this number designation is determined by the amount of abrasive mineral that can pass through a mesh screen with specific size openings. Therefore, a 40 grit abrasive particle will pass through a mesh

What is your terms of payment?

T/T 30% as deposit, and 70% before delivery. We’ll show you the photos of the products and packages .before you pay the balance.

Amount of abrasive applied:

This decision is made by knowing the type of material you will be working with. Open Coat – Here, the abrasive granules cover from 50% – 70% of the backing and are set at pre-determined spacing to reduce

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

What is the warranty policy?

Firstly, We make sure the quality before the goods to be packed, if clients get the item with Substandard products, We have warranty for our clients,we will ship out the new replacements.

How do i prevent moisture contamination in the abrasive?

Moisture contamination is the number one reason customers call Technical Support. Fortunately, it is usually preventable. There are 4 key ways to keep your abrasive free of moisture:1.Store abrasive properly and always make sure bottles are tightly closed

What is the structure?

Structure is basically the spacing between abrasive grains.  An open structure would be 12 or higher while a closer structure would be 6 or so.  Here again, the structure depends on a variety of factors not the least

What is fepa and what does it do?

FEPA is the Federation of European Producers of Abrasives. Its mission is to develop and publish standards, documents and comprehensive safety instructions for the abrasive industry. Abrasive grain sizes are produced and sold according to the FEPA standard,
