Corundum Ceramic Media SCT
Corundum Media SCT is a high-density, high-cutting ceramic abrasive media produced by HuaTong Polish from premium virgin corundum sand and a ceramic binder. Each triangular (SCT) piece is sintered at high temperature for maximum toughness and a consistent, aggressive cutting edge — ideal for fast deburring, deflashing and surface refinement of metal workpieces in tumbling and vibratory mass finishing.

Applications
Corundum Media SCT is engineered for the deburring, deflashing and descaling of ferrous and non-ferrous metal parts — automotive components, fasteners, castings, stamped parts and CNC-machined items needing a fast, aggressive surface clean before polishing or coating.
Why Choose HuaTong Corundum Media SCT
- Extremely strong cutting force for fast burr and flash removal.
- Consistent quality from non-recycled corundum sand.
- Versatile shapes for vibratory and centrifugal finishers.
Tip: for a more refined, brighter finish, pair with Polishing Media SCC.
Frequently Asked Questions
What is the difference between SCT and ACT corundum media?
Both are corundum-based ceramic media but differ in shape and cutting behavior. SCT (triangular) offers sharp edges for fast initial stock removal, while ACT balances cutting with surface finish. Contact HuaTong for a recommendation.
Which machines can use Corundum Media SCT?
SCT corundum media works in standard vibratory bowl/tub finishers, centrifugal disc and barrel tumblers, provided the mesh size fits the workpiece geometry.
How much media do I need?
A typical ratio is about one part media to one part workpiece by volume, varying with part size and finish. Send a sample or drawing and we will recommend a load plan.
