Product introduction
The 20-30 mesh ceramic foundry sand is used for the cleaning and polishing of copper and aluninum castings. Compared with the the price of chromite sand and zircon sand. It is easy to clean and won't stick to the castings.
Advantages: Particle size: 0.03 mm, fine and uniform particles, moderate hardness, high toughness, good self-sharpening, less consumption, can be recycled use, good performance for grinding of finished castings, stable chemical composition, abrasion, acid and alkali resistance.
