Physical Properties of Abrasive Grains

Hardness: Resistant ability of abrasives when a compressive force is applied. Hardness are classified into scratch hardness and indentation hardness based on different modes of compressive force. Moh's hardness belongs to the former, and knoop hardness to the latter. Generally, the higher the major chemical composition content in abrasives, the higher the hardness.
