As one of the most important raw materials for producing hard alloys, the particle morphology, size, particle size distribution range, and impurity content of tungsten carbide (WC) powder directly impact the quality and application of hard alloys. Based on particle size differences, WC powder is categorized into ultra-coarse tungsten carbide, micron tungsten carbide, submicron tungsten carbide, sub-nanometer tungsten carbide, and nano tungsten carbide. So, what are the advantages and disadvantages of submicron WC particles compared to other sizes?

During the operation of a CT machine (short for Computerized Tomography X-ray Scanner), the precise projection of X-rays and radiation protection are core technical requirements, with tungsten alloy shielding components playing a pivotal role in achieving this balance due to their excellent performance. The CT machine generates images through X-ray beam tomography of the human body; inadequate radiation shielding not only threatens the health of medical personnel and patients but may also interfere with the normal operation of the equipment's precision components, making the performance of shielding components critical to equipment safety and imaging quality.

In the field of tumor radiotherapy, radiotherapy equipment uses high-energy rays (such as X-rays and gamma rays) to kill cancer cells while minimizing radiation damage to healthy tissues. Tungsten alloy shielding components, with their exceptional radiation absorption capability, serve as a critical protective element in achieving this goal. The radiation energy in radiotherapy equipment is generally higher than the diagnostic-level rays used in CT machines, placing more stringent requirements on the density, stability, and structural design of shielding materials.

The manufacturing process of high-density tungsten alloy shielding components centers on powder metallurgy technology, combined with subsequent processing, forming a mature production workflow. The specific steps are as follows:
