Silicon Carbide Green 24 mesh

High-Purity SiC for Demanding Industrial Applications

Green Silicon Carbide is manufactured from silica sand and petroleum coke in electric resistance furnaces at high temperatures. The resulting crystalline structure is exceptionally pure, with a hardness second only to diamond and boron carbide. The 24 mesh particle size is a workhorse in the abrasive blasting industry, offering an excellent balance between impact energy and particle density for rapid cleaning and profiling.

This abrasive is specifically chosen for applications where iron contamination must be avoided, such as on non-ferrous metals, stainless steel, and in critical component manufacturing. Its sharp, angular grain shape cuts faster and produces a more uniform anchor profile than many conventional abrasives, leading to superior coating adhesion.

Key Features and Performance Benefits

• Exceptional Hardness: With a Knoop hardness near 2800, it easily cuts through tough substrates, hard coatings, and corrosion.
• High Friability: The grain continuously breaks down under impact, exposing new, sharp cutting edges for a consistent cut rate throughout its life.
• Low Iron Content: The high purity of the green grade minimizes the risk of ferrous contamination on blasted surfaces, preventing after-rust on stainless steel and non-ferrous alloys.
• Versatile Packing: Supplied in 25 kg bags, 50 kg bags, 1-ton jumbo bags, and drums to suit any operation, from small job shops to large-scale automated blasting facilities.

Typical Applications for 24 Mesh Green SiC

The 24 mesh size is a versatile, medium-coarse grit used across multiple industries. Its aggressive cutting action and consistent particle distribution make it a reliable choice for:

• Blasting Hard Metals: Cleaning and profiling titanium, stainless steel, and hardened steel components where ferrous abrasives are prohibited.
• Surface Preparation for Coatings: Creating a sharp, angular anchor profile on hard substrates to ensure maximum adhesion of thermal spray coatings, HVOF, and high-performance paints.
• Glass Etching and Stone Profiling: Used in architectural and monumental work for deep etching and surface texturing on glass, granite, and marble.
• Ceramic and Composite Finishing: Deburring and surface finishing of advanced ceramics and composite materials in aerospace and medical device manufacturing.
• Wire Sawing and Slicing: As a loose abrasive in the wire sawing of silicon ingots, quartz, and other hard crystals.

Handling and Selection Guidance

To achieve optimal results with Silicon Carbide Green 24 mesh, consider the following operational parameters:

• Blast Pressure: Effective at standard blasting pressures of 60-100 PSI. Due to its friability, excessive pressure can accelerate breakdown. Start at a lower pressure and increase to achieve the desired profile and cleaning rate.
• Nozzle Selection: Use a venturi nozzle for maximum particle velocity. Due to the abrasive's hardness, boron carbide or composite tungsten carbide nozzles are recommended for long life.
• Recycling: Green SiC is friable and will break down. Its recyclability depends on blast pressure and the hardness of the substrate. In pressure blast systems, it can typically be recycled 3-5 times before becoming too fine for the initial profile requirement. Used media can often be downgraded to a finer mesh application.
• Health and Safety: Always use in a contained blast environment with proper dust collection. Operators must wear approved respiratory protection, as airborne silicon carbide dust is a respiratory irritant.
