Mitutoyo 617675-516 Zero Cera Gage Blocks with CTE, 50mm

Features:

• 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

The Mitutoyo rectangular Zero CERA gage blocks have a thermal expansion coefficient 1/500 that of steel at 20±1°C for unmatched, exact precision. There is almost no secular change in dimension and coefficient of thermal expansion.
