Why is silicon carbide disc brakes are so expensive

2010-3-4 · The grinding wheels are a cheap aluminum oxide(I think)/silicon carbide composite vs. the the brakes which are a different composite that has much higher engineering and manufacturing standards. If a cutting disc blows up it''s not as big a deal as your breaks failing.

Information on Sanding Belt Grain Material

SILICON CARBIDE: Black in color. The hardest and sharpest manufactured abrasive grain. This is the only coated abrasive that will cut through hard or brittle surfaces such as glass, marble, tile, granite, carbide or hardened finishes. The finer grits are ideally suited for finishing on many surfaces and hardened metals.

Grinding wheel for tungsten electrode - …

2017-2-26 · For those asking how a softer metal can get eedded into a hard tungsten electrode, look no further than your aluminum oxide (or silicon carbide, or diamond) grinding wheel. Your grinding wheel is considerably harder than any metal you grind with it, yet after grinding, you will find particles of metal eedded all over the surface of the

What is the best abrasive for aluminum - Festool …

2019-5-7 · Metal needs to get sanded much farther than 220 for a smooth finish. 400 and even 600 grit will leave a rough finish. I recommend going to at least 1000 grit and perhaps 1500 grit. No need to get anything fancy, normal aluminum oxide sandpaper works fine but silicon oxide will last longer. I use the wet/dry type and use water as my lubricant.
