Silicon Carbide Black 70 mesh

Why Choose Black Silicon Carbide 70 Mesh?

Black silicon carbide (SiC) is one of the hardest man-made abrasives available, second only to diamond and boron carbide. The 70 mesh particle size is a medium-coarse grit that delivers a powerful combination of high impact energy and a controlled profile. It is the abrasive of choice for jobs where aluminum oxide is not aggressive enough or wears out too quickly.

This material is characterized by its angular, blocky grain shape and high friability. Unlike rounded media, the sharp edges slice into the substrate, removing coatings, rust, and scale rapidly. As the grain works, it micro-fractures to stay sharp, preventing the glazing and dulling common with tougher, less friable abrasives. This self-sharpening action ensures a consistent surface finish from the first part to the last.

Key Applications for 70 Mesh SiC

The 70 mesh size is a workhorse in the blasting room. It is coarse enough for rapid stripping yet fine enough to provide a uniform anchor profile for coatings. Common industrial uses include:

• Hard Metal Preparation: Cleaning and profiling tungsten carbide, hardened steel, titanium, and other tough alloys prior to thermal spraying or coating.
• Stone and Monument Engraving: Used in automated and manual blasting systems for etching designs into granite, marble, and other hard stone.
• Glass Frosting and Etching: Creating a uniform, decorative matte finish on glass panels and architectural glass.
• Automotive and Aerospace: Surface prep on high-value components where a clean, reactive surface is critical for bonding.
• Non-Slip Surface Creation: Blasting concrete or metal floors to create a high-friction, anti-slip profile.

Selecting the Right Pack Size for Your Operation

We understand that every job is different. That's why we offer flexible packaging to match your consumption rate and storage capabilities. Our standard pack options are designed for convenience and material integrity:

• 25 kg Bag: Ideal for small job shops, maintenance teams, and testing a new abrasive grade.
• 50 kg Bag: A practical size for regular use in manual blast cabinets and small pressure pots.
• 1 Ton Jumbo Bag: The most cost-effective option for high-volume blasting rooms and automated systems. Minimizes handling and changeover time.
• Bulk Tote / Drum Pack: Available for specialized dispensing systems or export orders. Contact us for custom packaging requirements.

We recommend ordering a sample quantity first to validate the cut rate and finish on your specific substrate. Our team can then help you forecast consumption and set up a scheduled delivery plan for bulk orders.
