Corundum Ceramic Media ACT
Corundum Media ACT is a high-density, high-cutting ceramic abrasive media made by HuaTong Polish from premium non-recycled corundum sand and a ceramic binder. The angular (ACT) pieces are sintered at high temperature for maximum toughness and a consistent, aggressive cutting edge — the go-to choice for fast deburring, deflashing and descaling of metal workpieces in vibratory and tumbling mass finishing.

Applications
Corundum Media ACT 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. Its strong cutting action quickly removes burrs and flash before polishing, plating or coating.
Why Choose HuaTong Corundum Media ACT
- Extremely strong cutting force for fast stock removal and cycle-time savings.
- Consistent quality from virgin, non-recycled corundum sand.
- Multiple shapes and sizes to suit vibratory bowl, tub, disc and centrifugal finishers.
Tip: for a more refined, brighter finish after deburring, pair ACT with Polishing Media SCC.
Frequently Asked Questions
What is the difference between ACT and SCT corundum media?
Both are corundum-based ceramic media with very strong cutting action, differing mainly in shape geometry. ACT angular pieces suit general-purpose deburring and deflashing, while SCT triangular pieces provide sharp edges for aggressive initial stock removal. Contact HuaTong to match shape to your part.
Which machines use Corundum Media ACT?
ACT corundum media works in standard vibratory bowl and tub finishers, centrifugal disc finishers and barrel tumblers, provided the mesh size fits the workpiece geometry.
How much media should I load?
A typical ratio is about one part media to one part workpiece by volume, varying with part size and the finish required. Send your part or drawing and HuaTong will recommend a load plan.
