The result is an abrasive with the ability to fracture at a controlled rate at

Difference in Sharpening Stone Materials

The Aluminum Oxide oil stones are a very popular man made choice. The most popular are called India Stone which are made by Norton. These stones can cut fast, and can also produce a fine edge on tools and knives. The grading system for these stones is generally labeled fine, medium, and coarse. These stones are often brown or orange in color.

''A'' is the grit type (in this case aluminum oxide), ''60'' is the grit size, ''I'' is the relative hardness, ''10'' is the structure, and ''VS'' is the type bond (VS for this company means vitrified bond. There are variations too.

Aluminum Oxide - an overview | ScienceDirect Topics

Aluminum oxide is an electrical insulator but has a relatively high thermal conductivity (30 Wm −1 K −1) for a ceramic material. Annual world production of alumina is approximately 45 million tons and over 90 percent of which is used in the manufacture of aluminum metal.

Silicon carbide stones | BladeForums

2014-5-11 · If you''re looking specifically for silicon carbide in finer grits, just use the wet/dry paper. Most SiC stones will only be found in coarse or medium grits (relatively), as compared to the higher finish afforded by the wet/dry paper in grits of ~400 and higher.

What''s the Difference: Aluminum oxide, silicon carbide

2011-11-10 · Aluminum oxide. Aluminum oxide is the most common abrasive in woodworking sandpaper. It works well on a nuer of materials, including bare wood, painted surfaces, and metal. In its most basic form, this furnace-produced mineral does not fracture easily. Instead, it tends to wear down until it becomes too dull to cut efficiently.
