خواص فیزیکی مهم کاربید سیمانی

1. Density

Indicates the accuracy and denseness of the cemented carbide composition.

2.Hardness

Rockwell hardness HRA, Vickers hardness HV, indicating the ability of cemented carbide to resist plastic deformation.

3.Magnetic saturation

Generally indicates the level of carbon content in cemented carbide.

4. Coercive magnetic force

Generally indicates the size of the average grain size of WC.

5. Flexural strength

The ability of the material to resist bending without fracture, mainly used to examine the strength of brittle materials. It is a comprehensive reflection of the manufacturing level of cemented carbide, and it is easy to find the material defects by fracture observation.

6. Impact toughness

Impact toughness indicators of practical significance is to reveal the material’s tendency to become brittle, is to reflect the metal material resistance to external impact loads.

7. Fracture toughness

It refers to the measure of the ability of the material to prevent the expansion of macroscopic crack instability, but also the material resistance to brittle damage toughness parameters

8. Wear resistance

The weight or volume of material wear under standard conditions.

9. Corrosion resistance

The ability of a material to resist the corrosive and destructive effects of surrounding media.
