All provided data are approximate values, depend on the application, environment and test conditions. Coating hardness HIT [GPa] measured by nano indentation according to ISO 14577. Hardness can be adapted to the application. Friction coefficient (dry) compared to the steel determined by ball-on-disc dry test with a steel sphere according to ASTM G99. During the running-in the indicated values may be exceeded. Maximum service temperature [° C] These are approximate values.

High hardness: protection against abrasive wear, longer tool life, lower production costs.
High thermal stability up to 500 ° C: possibility of MQL and dry processing.
Protection against adhesive wear: longer tool life and better quality of the processed component.
dialong® has proven effective on cutting tools for turning, milling, drilling, countersinking, boring of non-ferrous materials such as:
- aluminum alloys up to 13% of Si
brass, copper, bronze, silver, gold, platinum
- some types of titanium
- graphite, FR4 PCB data sheets and composite materials
wood, plastic, epoxy resins

Flexibility at customers' service.

 

dialong® is applicable on a wide range of materials and the thickness can be customized according to the application field.

Circular saws.

 

With dialong® the teeth of circular saws will keep their cutting edge for a long time.
