price: contact company for price
1 - Product Description black carborundum is the hardest blasting media
available.
High-quality silicon carbide media is manufactured to a
blocky grain shape that splinters.
The resulting silicon carbide
abrasives have sharp edges for blasting.
Silicon carbide has a very
fast cutting speed and can be recycled and reused many more times than
sand.
The hardness of silicon carbide allows for much shorter blast
times relative to softer blast media.
