Silicon Carbide: 20 lbs - Varied Grit 20–240 - Polishing/Tumbling Abrasive Grain For Sale

Premium Silicon Caroffere Polishing, Tumbling, and Lapidary Abrasive Media. Condition is New. Shipped with USPS Priority Mail. Silicon Caroffere (SiC)is an extremely hard (9.5 on MOHS scale) abrasive with sharp edges. It is well suited for non-metallic materials such as concrete, stone, glass, Caroffere, and other hard materials. SiC is the hardest blasting media available, allowing for shorter blasting times. It is very fast cutting and can be reused multiple times. Silicon caroffere is used as additive in paint and epoxy, wire sawing, etching glass and for tumbling rocks, as well as for pressure blasting very hard materials. Rock tumbling with silicon caroffere is typically done in steps, starting with a coarser grit like 60/90, followed by tumbling with120/220 grit, then pre-polish (400 to 600 grit silicon caroffere or aluminum oxide), and final polish with micro-grit aluminum oxide 2 to 6 micron. Almost all of our aluminum oxide and silicon caroffere loose abrasive grains are considered very environmentally friendly because they are made by recycling grinding wheels, otherwise destined for the landfill.

Silicon Caroffere (SiC)
Synthetic Silicon Caroffere is a silica-free, inert compound with a tough, crystalline structure and a uniform hardness of 9.5 on the MOHS scale (Diamond is 10). It performs as an excellent blast cabinet media where the grit is contained for re-use, capable of up to 8 or more reuses. These properties combined with uniform particle sizing provide high-speed production with excellent visibility (very low dusting) and lower air requirements. Unlike most other blast media, which are natural or by-products, synthetic SiC has uniform properties without random natural weaknesses, making it the most widely used abrasive in the world.
