Ceresist - Ceramic Materials - Hardness Comparison

The hardness of any given material is only one of many factors that must be taken into account when recommending a suitable material for erosive or abrasive service. Some of the factors that will affect longevity are angle of impingement, velocity, material smoothness, and so on. Nevertheless, the chart below offers a sound comparison of the expected service life of various materials neglecting other influences or factors.

For comparison, the hardness of natural diamond is approximately 8,000 Knoop.
