Silicon Carbide – Reaction Bonded
Featured Product from Insaco, Inc.
Silicon Carbide – Reaction Bonded
Silicon Carbide is among the hardest of ceramics, and retains hardness and strength at elevated temperatures, which translates into among the best wear resistance also. Additionally, SiC has a high thermal conductivity, especially in the CVD (chemical vapor deposition) grade, which aids in thermal shock resistance. It is also half the weight of steel.
Based on this combination of hardness, resistance to wear, heat and corrosion, SiC is often specified for seal faces and high performance pump parts.
Reaction Bonded SiC has the lowest cost production technique with a course grain. It provides somewhat lower hardness and use temperature, but higher thermal conductivity.
Direct Sintered SiC is better grade than Reaction Bonded and is commonly specified for high temperature work.
CVD SiC is a face centered cubic, polycrystalline form produced by chemical vapor deposition. This material is extremely pure, and is specified for it’s excellent thermal conductivity approaching 300 W/mK. It is considerably more expensive to produce than the sintered or reaction bonded grades.

High Precision Machining of Hard Materials
Since 1947 Insaco® has been a precision machining and polishing fabricator of parts from all technical ceramics, sapphire, glass and quartz. We machine these materials to very precise tolerances (many times measured in millionths of an inch) for dimension, flatness, wedge and roundness or cylindricity. Our customers typically have a critical application that requires extremely tight tolerances in ultra-hard materials. We also have the capability to grind and polish spherical radius parts in a variety of hard materials, both inside and outside diameters, to optical requirements.
features include:
- Extremely high accuracy and tight tolerance machining
- Lights-out manufacturing
- Machine automation including large capacity envelope
- Automated centerless grinding
- High efficiency/low cost volume production
- Low-volume prototype machining
- 5-axis machining capability
- ITAR compliant
- High-volume robotic machining
- Video inspection and a Class 100 Cleanroom
- Extensive Quality Control protocols
- Sapphire tubes and polishing
Insaco
Insaco has been fabricating precision parts from all technical ceramics since 1947. Approximately a third of our machining involves sapphire, but our capabilities go way beyond that. Insaco engineers welcome inquiries from designers contemplating specifying technical ceramics for their applications, whether prototype or full production. We only ship parts that meet agreed-to requirements, but are often able to respond to challenges and achieve results others cannot.
Insaco also has extensive inspection and documentation procedures so parts are always to print. With a seasoned team of engineers and machine operators we are available to discuss your application needs including alternative materials and cost drivers. please click here to send a request, or visit our Frequently Asked Questions page.
