Tungsten wire, as a light source for retro lamps, is widely popular due to its unique optical characteristics and nostalgic aesthetics, especially in decorative lighting.

Tungsten wire has a wide range of uses. Its exceptional physical properties, such as its extremely high melting point (approximately 3422°C), excellent corrosion resistance, and good electrical conductivity, have led to its widespread application in industry, technology, and everyday life.

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:

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, influencing the effectiveness of radiation detection and treatment. Why is it entrusted with this responsibility, and what unique properties does it possess?
