[2025-10-01T10:12:22.232672] [PI reasoning] **Determining hardness test for Co-Cr alloys**

I need to find out which hardness test is appropriate for measuring Co-Cr alloy dental hardness. The Vicat apparatus is not suitable since it's for cement. Cold bend tests are also not related to hardness measurements. However, the Rockwell hardness test is used for metals, including Co-Cr alloys, and it can be valid here. While Vickers and Brinell are common for dental casting alloys, I'll affirm that Rockwell is acceptable too. Now, I want evidence to support this!
