Silicon Carbide Green 40 mesh

High-Purity SiC for Demanding Blasting Applications

Green Silicon Carbide (SiC) is one of the hardest and sharpest abrasives available for dry and wet blasting. The 40 mesh grade offers an optimal balance of aggressive stock removal and a controlled anchor profile, making it suitable for etching, deburring, and cleaning hard substrates. Its high purity minimizes the risk of ferrous contamination on non-ferrous workpieces.

This abrasive is friable, meaning it fractures under impact to continuously expose new, sharp cutting edges. This self-sharpening characteristic provides a consistent cut rate throughout its usable life, which is a key advantage over softer, more rounded media that tend to glaze and lose effectiveness. It is commonly used in pressure blasting and suction blasting systems.

Key Features and Benefits

• Exceptional Hardness: Just below diamond and boron carbide, it cuts quickly through hard materials like tungsten carbide, ceramics, and chilled iron.
• High Purity: The green grade is over 99% pure SiC, preventing metallic contamination on sensitive substrates like stainless steel and titanium.
• Sharp, Angular Shape: Provides a high cutting speed and produces a sharp, angular surface profile ideal for coating adhesion.
• Friable Nature: Self-sharpening grains maintain a consistent cut rate and reduce the need for frequent media top-ups.
• Recyclable: Its toughness allows for multiple use cycles in controlled blasting environments, offering better cost-per-use.

Typical Industrial Applications

Silicon Carbide Green 40 mesh is specified for precision work where other abrasives fall short. Common applications include:

• Aerospace Component Preparation: Deburring and texturing turbine blades and other critical parts prior to thermal spray coating.
• Ceramic and Glass Etching: Creating a frosted finish or preparing surfaces for bonding without causing micro-cracks.
• Wire Sawing: Used as a slurry abrasive for slicing silicon ingots, quartz, and other hard crystals.
• Automotive and Foundry: Cleaning and finishing hard metal castings, removing scale, and preparing surfaces for specialized coatings.
• Optics Manufacturing: Fine grinding and matting of optical glass components.
