Tungsten heavy alloy shield is made with high tungsten content and low amounts of Ni, Fe or Ni, Cu. Some tungsten alloy shields are added Co, Mo or Cr, etc. The density of tungsten heavy alloy could be as high as 16.8-18.8g/cm3.

Tungsten alloy syringe shield with lead glass window is thin, lightweight and easy to use. Such a high quality syringe is designed to attenuate FDG F-18 or Tc-99, thereby reducing hand exposure for clinicians during preparation and administration of radiopharmaceuticals. It fits most disposable syringes. And it is easily sanitized with alcohol wipes.

Tungsten alloy collimator is a key component that affects the imaging quality of gamma camera (γ camera). Tungsten alloy collimator on a gamma camera is to realize spatial positioning, so that rays from different spatial parts irradiate a specific position of the scintillator. Studies have shown that under the principle of taking into account both geometric resolution (or angular resolution) and detection sensitivity, reducing the transmission effect as much as possible is the core goal of γ camera collimator design.

Tungsten alloy post-patient collimator is present between the patient and the detector on a CT machine, which serves to ensure good image quality, minimize the interference of scattered rays from other directions, and to reduce unnecessary radiation doses for the patients. Tungsten alloy post-patient collimator improves the slice sensitivity profile by giving a more rectangular shape.

Tungsten alloy pre-patient collimator is the tungsten alloy collimator located in front of the X-ray tube on a CT machine, with characteristics of high density, smooth surface and good dimensional accuracy. Tungsten alloy pre-patient collimator is the first component through which X-rays pass, and is mainly used to control the thickness of the scanning layer by controlling the width of the X-ray beam in the direction parallel to the long axis of the human body. The X-rays emitted from the X-ray tube are tapered, and becomes a thin beam after passing through the slit-shaped tungsten collimator.

Tungsten alloy foil is an important anti-scattering component on a CT detector. And there may be 9-129 tungsten alloy anti-scatter foils on a CT detector. Research shows that anti-scattering foils made of high quality tungsten alloy is not easy to deform during long-term use, so the channel width will not change, avoiding signal distortion when X-rays pass through the deformed traditional ray channel, and ensuring imaging quality.

Tungsten alloy collimator applied for medical CT machine includes tungsten alloy pre-patient collimator and tungsten alloy post-patient collimator. These collimators have the characteristics of high density, smooth surface and good dimensional accuracy.

Tungsten alloy radiation shield applied for gamma knife includes a tungsten alloy collimator and its combination block. Their surface is smooth, the size is fine, and the quality is reliable. But why use tungsten alloy radiation shield such as tungsten alloy collimators for gamma knife?

Tungsten carbide thread milling cutter fabricated with ultra-fine grain tungsten carbide is specially designed for machining small diameter thread. Such a thread milling cutter has advantages of high hardness, excellent wear resistance and durability, so that it reduces the number of blade replacements, thereby improving production efficiency.

How to choose tungsten carbide thread milling cutter? Tungsten carbide thread milling cutters have two main types: single-row thread milling cutters and multi-row thread milling cutters. And there are different shanks including hydraulic shanks, spring shanks and hot tension shanks.
