Gauge Block: High-Precision Calibration Standards for Metrology

Ceramic gauge blocks are non-magnetic due to being manufactured from ZrO₂ or silicon carbide off. They possess strong corrosion resistant properties, allowing them to be used safely in the cleanroom and medical device fields. Moreover, ceramic gauge blocks possess ultra-low thermal expansion (≤3×10⁻⁶/°C) and high rigidity making them ideal for calibration in the aerospace and semiconductor industries. Surface roughness is ensured to be Ra≤0.01μm which makes wringing possible but also prevents chemical reactions with the measured parts.
