White Fused Alumina WFA Abrasives Media

Knives will become dull over time, so they often need to be sharpened to make them sharp. There are hundreds or even thousands of good knives. If you don't sharpen the knife, even a powdered steel knife costing thousands of dollars will become dull. Eclipsed. The use of a whetstone when sharpening a knife is also a critical step. The whetstones on the market are divided into white fused alumina whetstone, brown corundum whetstone, and silicon carbide whetstone. So which whetstone is better?

1. White corundum whetstone

Whetstone is actually a good choice. A double-sided whetstone with suitable particle size can meet the needs of most families. The particle size is about 240# to 400# for rough surface, 800# to 1000# for fine surface, and 1000#. A whetstone can be used to sharpen a blade that can be easily shaved. There is no need to pursue a higher mesh, which is too sharp and dangerous. There are many whetstones for sale on Taobao. You can choose from brown corundum, white corundum and ruby stones, which are all relatively durable. Because white corundum is white in color, high in purity, good in crystal, and high in volume density, it has the characteristics of good self-sharpening, strong grinding ability, low heat generation, high efficiency, acid and alkali corrosion resistance, high temperature resistance, and good thermal stability. Therefore, most families use white corundum whetstones.

2. Brown aluminum oxide whetstone

The brown corundum whetstone is a fine whetstone that absorbs iron slowly and is used to sharpen large knives.

Grinding kitchen knives should also be divided into coarse and fine grinding processes; coarse grinding uses a sandstone + emery (or brown corundum) grinding wheel; and then fine grinding uses a silicon carbide grinding wheel; it is better to separate coarse and fine grinding. Each has its own advantages and disadvantages. If it needs to be softer and finer, then use silicon carbide. If it needs to be sharpened to a large extent and does not require smoothness, then the emery whetstone is more effective, but it will lose a lot of grit.

The white corundum abrasive produced by Zhengzhou Mayjoy Abrasives Co., Ltd White aluminum oxide Factory is made of high-quality alumina powder as raw material and smelted by electric melting. Its hardness is slightly higher than brown corundum, slightly lower toughness, high purity, good self-sharpening, strong grinding ability, low calorific value, high efficiency, acid and alkali corrosion resistance, high temperature resistance, and good thermal stability. Use it to make abrasive tools, suitable for grinding high carbon steel, high speed steel, stainless steel, etc. White alumina whetstone companies are welcome to purchase white corundum micro powder.
