Product Introduction
Silicon Carbide (SiC) is a high-performance abrasive made from silica sand and carbon, known for its exceptional hardness (9-9.5 on the Mohs scale) and durability. Available in green (high-purity) and black (lower-grade) types, it is used in applications such as grinding, polishing, surface preparation, and sandblasting. Green Silicon Carbide is ideal for fine grinding and precision work, while Black Silicon Carbide is better suited for heavy-duty and rough applications. It is commonly packaged in 25kg/50kg sacks or bulk bags, and is widely used in industries like automotive, aerospace, and metalworking for its versatile and superior abrasive properties.
Main Products Type
Brown Fused Alumina Grit
Coarse grains of brown corundum, ideal for sandblasting, grinding wheels, and other abrasive applications. It offers high hardness and durability for tough surface preparation.
Brown Fused Alumina Powder
Fine particles of brown corundum, typically used for polishing, lapping, and high-precision applications. It provides a smooth finish and is ideal for surface conditioning and coatings.
