Opus ceramic gauge blocks (Zirco-Blocks) are manufactured from an exceptionally pure grade of zirconia ceramic.
The commonly held belief that all ceramic materials are brittle and prone to catastrophic failure can now be dispelled with the remarkable zirconia ceramic material which used to manufacture Opus Zirco Gauge Blocks
Opus Zirco Gauge Blocks are an effective substitute for the traditional steel gauge blocks and out perform them in many applications.
The exceptional material combined with Opus’s specially developed lapping techniques produces a gauge of exceptional quality and value.
Opus Ceramic Gauge Blocks are rigorously checked for flatness of their measuring surfaces using a laser flatness interferometer.
Each gauge block is then calibrated in our own UKAS accredited laboratory for length and graded according to the relevant standard
Gauge blocks can be supplied in sets or as individual sizes, special sizes up to 100mm (4 inches) in length can also be supplied upon request.
