silicon carbide vs aluminum oxide

Sandcarving with Aluminum Oxide Versus Silicon Carbide ...

 · Aluminum oxide grit is significantly less expensive and has the same relevant recirculation and wear rate as silicon carbide, but is blocky and not as angular, and breaks down in similar shape. Silicon carbide grit is more angular and stays angled as it fractures and stays sharper; the cutting speeds tend to be faster but lighter.

Review of ballistic performance of alumina ... - ScienceDirect

 · Such a combination was proposed in Ref. in a general form for alumina, aluminium nitride, boron carbide, silicon carbide, and titanium diboride: (7) K I C 2 (1 − ν) 2 2 E 2 where K I C is the fracture toughness, E is the elastic modulus, and ν is the Poisson's ratio. (8) Y B ρ where Y B is the dynamic ultimate strength and ρ is the ...

When to use a Silicon Carbide Stone and ... - …

 · Aluminum oxide and silicon carbide will effectively cut almost any steel, including high-vanadium steels, up to about 400 ANSI grit. Diamonds and other super-abrasives are only a requirement for high vanadium steels at grits in excess of 400 ANSI. And those high-vanadium steels generally give the greatest performance with a toothy edge, anyhow ...

What are the different types of abrasive grain ...

Silicon Carbide vs. Aluminum Oxide. Both grains have advantages on certain materials. S/C has a long sharp needle-like grain structure which permits fast stock removal, but generally has a short life. Aluminum oxide has a "blocky' grain structure. This durable grain generally will last longer than S/C.
