Mitutoyo 613804-51B Metric Gage Block With CTE, Rectangle Shape, 175 mm L, Ceramic

The Mitutoyo rectangular gage blocks with CTE comes with a highly accurate thermal expansion coefficient measured with a high-accuracy, double-faced interferometer (DFI) to guarantee high accuracy.

• The Mitutoyo rectangular gage blocks with Thermal Expansion Coefficient Data are available in nominal values from 100mm/4in to 500mm/20in. The high-accuracy gage block interferometer (GBI) guarantees high dimensional accuracy, and each block comes with a precisely accurate thermal expansion coefficient measured with a DFI
• Available in Metric and Inch gage blocks
• Available in steel and CERA gage blocks
• Specific, repeated heat treatment of steel blocks reduce deterioration change over time
• CERA blocks are free from dimensional change over time; have 10 times the abrasion resistance of steel gage blocks
• Advanced lapping techniques achieve the best flatness, surface roughness needed for gage blocks
• Grade: K class in ASME
• Uncertainty of thermal expansion coefficient: 0.035×10¯⁶/K (K=2)
• Uncertainty of dimension measurement: 30nm (k=2), for 100mm block

Standard/Approvals:ASME
