Bomas MOR Bars Earn Worldwide Acclaim at Increasing Rate
Now that’s a test of strength!!
MOR Bars are a staple in this industry and our machining of them has almost single handedly led to much broader relationships with some of the nation’s leading ceramic producers. Engineers and buyers alike respect and appreciate the Bomas difference in any Bomas controlled project; simple or complex.

Consistent precision from one piece to another – is why Bomas has been one of only a few high quality producers in the world for over 61 years.

Testing MOR Bars
This photo illustrates how MOR bars are broken for material strength. MOR = Modulus of Rupture. This is a Standard Test Method for Flexural Strength of Advanced Ceramics.
This illustration shows a 4-point test. As you can see, there are 4 contact points on the bar. There is also a 3-point test method.
Yes. Bomas can use almost any material you provide, including fused quartz.
Can you machine MOR Flexure test bars (3mm x 4mm x 50mm) from five 4″x 0.25″ siliconized silicon carbide disks?
Absolutely. The Bomas name has become synonymous with MOR Bars. After machining over 2,000,000 of them for customers worldwide, we can produce many from shapes and sizes.
I have 3 sets of hot pressed boron carbide plates that I need machined in 3 different sizes. Can you accommodate?
Absolutely. Let’s talk.
I have thirty‐six A size bars that need to be ground to the exact A size dimensions (2×1.5x25xmm) including chamfering and surface finishing. Can you do that?
Yes, we regularly provide such services.
I have 12 ceramic specimens that roughly have the dimensions of B size bars (according to the ASTM C1161 ‐ 18 standard, 3x4x45 mm). I need to have these cut in as many A size bars as possible (2×1.5×25 mm) including chamfering and surface finishing for 4‐point bend test.
We can do that for you.
I would like a quote to machine twenty ‘B’ sized bars of alumina ceramic material? Can you do that?
Absolutely. The Bomas name has become synonymous with MOR Bars. After machining over 2,000,000 of them for customers worldwide, we can produce just about anything you need. FYI ‐ there are 3 standard sizes: A, B, and C. A size are tiny and rare. B size are the most common.
