SiC 85% grit usually refers to black silicon carbide abrasive material with a minimum silicon carbide content of 85%, processed into grit sizes suitable for grinding and polishing use.

As an abrasive raw material, it is valued for:

• high hardness
• good wear resistance
• practical cutting performance
• suitability for polishing and grinding
• flexible grit sizes for different surface treatment needs

This grade is often selected for industrial users who need a more economical abrasive than high-purity specialty grades, while still maintaining dependable performance.

High hardness

Silicon carbide is known for its high hardness, which makes it suitable for grinding, polishing, and abrasive surface treatment. SiC 85% grit provides stable hardness for regular industrial finishing work.

Good cutting ability

Because of its sharp abrasive structure, SiC 85% grit can deliver practical cutting performance in grinding and polishing processes. It is suitable for applications where material removal and surface preparation are both important.

Good wear resistance

This material performs well in abrasive environments where repeated friction and surface contact occur. Its wear resistance helps maintain workable abrasive action during use.

Stable grit performance

For polishing and grinding applications, grit consistency matters. SiC 85% grit is available in multiple sizes to match different process stages, from rough grinding to more controlled surface finishing.

Cost-effective abrasive option

Compared with higher-purity silicon carbide abrasives, SiC 85% grit offers a more economical solution for industrial users who need workable performance and bulk supply support.

Metal surface grinding and polishing

SiC 85% grit is widely used in metalworking processes for:

• grinding
• deburring
• rust removal
• weld seam cleaning
• surface preparation before coating or finishing

It is suitable for regular industrial applications where abrasive efficiency and cost control are both important.

Stone and construction material processing

Because of its hardness and abrasive effect, SiC 85% grit can also be used in:

• stone grinding
• stone surface preparation
• edge treatment
• rough polishing
• construction material surface finishing

Its practical durability makes it suitable for large-volume abrasive use.

Ceramic and hard material grinding

SiC 85% grit is also applicable in selected ceramic and hard material processing tasks where abrasive hardness is required. It may be used for:

• ceramic grinding
• hard material surface treatment
• rough finishing
• industrial polishing processes

The exact grit size should be selected according to the target surface finish and workpiece material.

Abrasive blasting and surface treatment

This product can also be used in abrasive blasting and related industrial surface treatment processes, including:

• cleaning
• descaling
• roughening
• pre-treatment before painting or coating

For these uses, grit size and working method should be matched to the required surface profile.

Wear-resistant industrial uses

In addition to direct grinding and polishing use, SiC 85% grit may also be used as a wear-resistant aggregate or abrasive component in selected industrial applications.

SiC 85% grit offers several practical advantages:

• high hardness for abrasive use
• good cutting efficiency for regular grinding work
• suitable for polishing and surface preparation
• more economical than higher-purity abrasive grades
• available in multiple grit sizes
• suitable for bulk supply and continuous industrial purchasing
