Gauge block

Description
Version:
Made of ultra-pure ceramic zirconium oxide (ZrO2) manufactured in a sintering process.
Hardness:
With approx. 1350 HV about twice as hard as steel.
Tensile strength:
Up to approx. 70 % of the flexural strength of steel.
Insensitive to shock and impact.
Wear resistance:
Lasts about 10 times longer than steel.
No burrs. No plastic deformation. Scratches and small
defects have no influence on the measuring result.
The surface remains slip capable longer than steel.
Handling / care:
Highly resistant to alkalis, acids, oil, and grinding water.
No need for time-intensive degreasing before use
and re-greasing after use which is required for steel.
Low weight is an advantage for large sizes.
Temperature characteristics:
Expansion coefficient (9.5 ± 1.0) 10-6 K-1 similar to that of steel. Low thermal conductivity.
Anti-magnetic: Cannot be magnetised.
Slip capability:
The homogeneous, high density structure gives optimum holding, even to steel, and easy slip capability. Galling is excluded.
With free test certificate traceable to national standards:
Each gauge block is provided with its own unique identity number. The actual deviation from the nominal dimensions is recorded in the test certificate. Thus the absolute actual dimension is given.
Application:
Tolerance class 1 as working and adjusting master for gauge checking. For inspection rooms.
