GENERAL INFORMATION

Brown & Sharpe has years of experience manufacturing gage blocks and calibration equipment. Our gage blocks are made using the finest materials and are heat treated to assure durability and dimensional stability. Unique flat lapping and rounding techniques provide superior wringability for consistent accuracy. Each gage block is marked with a serial number.

PRODUCT APPLICATION

Which Material Do You Need?

Steel
Steel gage blocks have proven their reliability for more than a hundred years. This material remains the most commonly accepted for length standards. Steel gage blocks provide high resistance to wear associated with adherence to other gage blocks. However, steel must be protected against corrosion. Provided gage blocks are made from steel, properly handled and cared for, they will remain reliable for many years. Brown & Sharpe steel gage blocks have the following features:
• Highly alloyed steel.
• Hardness guaranteed to 800 HV.
• Artificially aged for optimum form and dimensional stability.
• Coefficient of thermal expansion:
(11.5 ± 1.0) x 10-6 K-1.

Tungsten Carbide
Gage blocks made with tungsten carbide are 10 times more durable than steel gages. They are designed for frequent use and possess superior wringing capabilities. Brown & Sharpe tungsten carbide gage blocks provide:
• Hardness guaranteed to 1400 HV.
• Coefficient of thermal expansion:
(4.23 ± 0.1) x 10-6 K-1.

Ceramic
Ceramic gage blocks are extremely resistant to wear and scratches. As a result, any minor damage to the wringability of their measuring face is unlikely. Corrosion resistant, these gage blocks are resistant to sweaty hands, and normal wear and tear. Manufactured from stabilized Zirconia, Brown & Sharpe ceramic gage blocks have the following key features:
• Impossible to magnetize.
• Hardness guaranteed to 1400 HV.
• Coefficient of thermal expansion:
(9.7 ± 0.8) x 10-6 K-1
