Tungsten carbide is an excellent material to manufacture gauge blocks from. Opus tungsten carbide gauge blocks are extremely accurate, stable and have excellent wringing characteristics.
Each gauge is manufactured from carefully selected materials having a hardness of approximately 1500 Hv, they set standards of surface finish that are beyond materials such as steel.
Opus has developed production techniques to ensure a micro-fine surface on every tungsten carbide gauge block that it produces. The Opus finish guarantees excellent wringing characteristics and a high resistance to wear.
