Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of diamonds, it is recommended to prioritize clarifying key technical parameters such as particle size, hardness, and thermal stability to ensure compatibility with processing or cutting scenarios.
  • In industrial grade grinding or drilling applications, the crystal integrity and impurity content of diamond may directly affect the equipment life, and specifications need to be selected based on specific operating conditions.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and companies with industry data support to balance procurement risks and efficiency.
  • For high-precision scenarios such as precision tool manufacturing, it is recommended to verify the uniformity of diamond crystal structure and compare it with the measured data provided by the supplier.
  • If purchasing for high temperature and high pressure environments, attention should be paid to the thermal conductivity and impact resistance parameters of diamond to avoid production interruption caused by material failure.
