Example of OD grinding; Silicon Carbide, CVD Silicon Carbide, Sintered & Reaction-Bonded Silicon Carbide, Silicon Nitride

Various test specimens are commonly machined from Silicon Carbide, CVD Silicon Carbide, Silicon Nitride, or the material you require.

Examples of MOR Bars; Alumina, Aluminum Nitride, Boron Carbide, Quartz, Silicone Carbide, Zirconia, Composite Materials

MOR Bars are machined from a wide variety of materials including Alumina, Boron Carbide, and Fused Silica, and of course the material you require.

Example of Chevron Notched Specimen; Aluminum Nitride, Boron Carbide

Chevron Notched test specimens are often machined from Aluminum Nitride, Zirconia, or the material of your choosing.




Yes, a Bomas advantage is the wide variety of materials we can successfully work with. That includes Boron Carbide, Macor, Glass, Mullite, Zorconia, and Industrial Grown Sapphire to name a few. While most materials are provided to us, we can special order materials to meet your needs.

Yes, we can do that.

Yes, we can supply and machine to your specifications.

Yes we do, and we welcome a discussion on all the materials we work with.

While most customers provide their own materials, we can source most materials.


While materials are typically provided by our clients, we can supply most any advanced ceramic or composite material you require. To that end, we welcome a ‘materials consult’ to discuss your goals. Our 60+ years of experience make the difference. Call us at 617-628-3831 or email either [email protected] or [email protected] and Let’s Talk Materials!
