Relationship between hardness and performance
Hardness is an important indicator of the performance of nylon sand materials, which reflects the material's ability to resist local pressure deformation.
Nylon sand with high hardness usually performs better in terms of wear resistance and compressive strength, but it may also lead to increased material brittleness and reduced impact resistance.
Precautions
When using PA6 nylon sand, the appropriate hardness range should be selected according to the specific application scenarios and requirements.
At the same time, other performance indicators of the material need to be considered, such as density, tensile strength, elongation at break, bending elastic modulus, etc., to comprehensively evaluate the applicability of the material.

To sum up, the hardness of PA6 nylon sand is generally in the range of 108-118 HRC, but the specific hardness value needs to be determined according to factors such as production process, material formula and subsequent processing. When selecting and using, the various performance indicators and application requirements of the material should be comprehensively considered.
