Types and Characteristics of Abrasivo Garnet
When we talk about the size of brown fused alumina oxide, we often mention brown fused alumina oxide F-grit, P-grit, and W-grit. While most people are familiar with P-grit, not many know about W-grit and F-grit, causing confusion. So today, we'll help you distinguish between them.
In brown fused alumina oxide, F-grit and W-grit are different specifications produced by different processes for different purposes.
Brown fused alumina oxide F-grit is a common abrasive with a grain size ranging from F4 to F320. Its chemical composition varies slightly depending on its particle size. Its characteristics include low magnetic material content, small crystal size, and impact resistance.
Usually, brown fused alumina oxide F-grit is used more on bonded abrasives, such as ceramic grinding wheels, grinding blocks, and resin grinding wheels, due to its high packing density and special particle shape. It can also be used in refractories and sandblasting.
The grain size of brown fused alumina oxide W-grit can be processed according to user requirements. Generally, brown fused alumina oxide W-grit is used more on coated abrasives, such as sand belts, sand cloths, and sandpapers, thanks to its pointed shape and relatively low packing density. It can also be used for grinding, polishing, precision casting, and other areas.
The grain size of brown fused alumina oxide W-grit is marked with the English letter "w" followed by an Arabic numeral. The larger the numerical value, the finer the abrasive particle size. Its grit markings include W1, W5, W10, W50, and W63, among others.
Brown fused alumina oxide W-grit is mainly used for coated abrasives. Its micro-powder shape is mostly sharp and needle-like, with a relatively low packing density and a relatively concentrated particle size distribution. Brown fused alumina oxide F-grit is used for bonded abrasives, with grains shaped like particles or so-called gemstones, and high packing density.
Although W-grit and F-grit are different, they both fall within the range of medium-sized sand in brown fused alumina oxide grit because they have fixed grit sizes.
Brown fused alumina for abrasive is mainly made from alumina and coke (or anthracite) through high-temperature smelting in an electric arc furnace. Grinding tools made of it are suitable for grinding metals with high tensile strength, such as various general-purpose steels, malleable cast iron, and hard bronze, and can also be used to make high-end refractories. Brown fused alumina oxide has the characteristics of high purity, good crystallization, strong fluidity, low linear expansion coefficient, and corrosion resistance. As verified by dozens of refractory manufacturing enterprises, the product has the characteristics of no explosion, no pulverization, and no cracking when applied. Its far higher cost-effectiveness than traditional brown fused alumina oxide makes it the best aggregate and filler for brown fused alumina oxide refractory materials.
That concludes the differences between brown fused alumina oxide W-grit and F-grit. If you would like to learn more about brown fused alumina oxide grit or powder, please continue to follow brown fused alumina supplier at HAOYUN NEW MATERIAL.
