Key Features & Benefits:
Unmatched Hardness & Sharpness: With a Mohs hardness of 9.5, Green Silicon Carbide is one of the hardest blasting media available. Its sharp, friable grains fracture to maintain fresh, cutting edges, ensuring fast cutting rates, reduced process time, and a superior etch on hard surfaces like ceramics, carbides, and alloys.
Exceptional Thermal Conductivity: This product excels in applications involving heat transfer. Its high thermal conductivity allows for efficient use in specialized processes like lapping and polishing of thermal components, or in any setting where heat dissipation during blasting is a concern, preventing workpiece damage.
Superior Chemical Inertness: F90 Green Silicon Carbide is highly resistant to acids, alkalis, and corrosion. This chemical stability ensures the media does not break down or contaminate the workpiece during blasting, making it ideal for cleaning and preparing surfaces in the chemical processing, aerospace, and precision foundry industries.
Consistent F90 Grit Size: The F90 classification provides an optimal balance between aggressive cutting action and desired surface finish. It is effective for removing tough coatings, creating anchor patterns, and delivering a clean, uniform surface profile without embedding or causing excessive wear to equipment.
Reusability & Cost-Efficiency: Despite its premium performance, this media offers excellent recyclability in closed-loop blasting systems. Its durability and longevity translate into lower consumption rates and reduced overall operational costs for severe applications.
Primary Applications:
Precision abrasive blasting and surface preparation of technical ceramics, tungsten carbide, and titanium components.
Etching and cleaning of intricate metal parts and molds in aerospace and automotive manufacturing.
Creating thermal pathways on surfaces and specialized lapping operations.
Cleaning and descaling reactors and components in the chemical and petrochemical industries.
