Precision gage blocks are the primary standards vital to dimensional quality control in the manufacture of parts. The four major characteristics that are necessary for a precision gage block are accuracy, surface finish, wear resistance and dimensional stability. Other factors are corrosion resistance, hardness, thermal conductivity and coefficient of expansion. The base material used for gage blocks is crucial in meeting the above criteria. While many materials have been tried, the major types available today are:
- Traditional high-grade steel gage blocks, which are generally used in shop floor environments
- Ceramic gage blocks have an advantage over regular steel. They will outwear regular steel and they will not corrode
- Chromium Carbide gage blocks are considered the top of the line – the finest available. They outwear regular steel and ceramic. In addition, they will not corrode and are very stable and accurate, and have exceptional “wringing” qualities
- croblox® Chromium Carbide – the superior gage block material. The reason that our Webber Gage Division emphasizes gage blocks made from Chromium Carbide is because they are the most stable measuring devices ever developed.
