Tungsten Wire Lighting in Incandescent Light Bulbs 16

The application of tungsten wire light-emitting in incandescent light bulbs is primarily based on its high melting point and excellent thermal radiation properties. The following is a brief description of its specific applications and principles: 1. Tungsten Wire Lighting Principle Tungsten wire, the core light-emitting element of an incandescent light bulb, emits visible light and thermal radiation when heated to a high temperature (typically 2000-2800°C) by an electric current. This phenomenon is based on the principle of thermal radiation: the…

What Is Tungsten Alloy Collimator？ 54

In a hospital imaging department, a patient lies on an examination table, about to undergo a CT scan. As the equipment activates, an invisible ray begins rotating around the patient’s body—this is the X-ray, capable of penetrating the body to clearly reveal internal structures, providing critical evidence for disease diagnosis. Behind these radiation applications, a key player operates quietly in the background: the tungsten alloy collimator. Though you may never have heard of it, it functions like a behind-the-scenes hero,…

Tungsten Alloy Collimator 32

Radiotherapy equipment is a specialized medical device used for tumor radiation therapy, with its core function being the generation and delivery of high-energy rays (such as X-rays, gamma rays, electron beams, and proton beams) to damage the DNA structure of cancer cells, inhibiting their proliferation and thereby treating tumors. However, radiation is a double-edged sword—it can harm surrounding healthy tissues while targeting cancer cells. At this juncture, a seemingly inconspicuous yet highly critical component—the tungsten alloy collimator—plays a vital role.…

Submicron Tungsten Carbide 42

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? By definition,…

Application of Tungsten Alloy Shielding Components in Radiotherapy Equipment 36

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…

Application Advantages of High-Density Tungsten Alloy Shielding Components 35

High-density tungsten alloy shielding components offer significant advantages over traditional lead-based shielding components in practical applications. Higher Shielding Efficiency: The density of high-density tungsten alloys ranges from 16.5 to 18.75 g/cm3, far exceeding lead’s 11.34 g/cm3. Generally, the effectiveness of ray shielding is positively correlated with material density. At the same thickness, tungsten alloy shielding components provide stronger attenuation of X-rays and gamma rays, meaning that with reduced material usage, their protective effect can match that of lead shielding components.…
