Industrial high density tungsten alloy shielding

Industrial Tungsten Alloy Shielding is a device used to prevent radiation and electromagnetic interference. Tungsten Alloy shielding parts have high density, high conductivity and excellent radiation resistance, and are widely used in the nuclear industry, electronics industry and other fields.

High specific gravity tungsten alloy is an alloy composed of tungsten as the matrix (W content 85-99%) and added elements such as Ni, Cu, Co, Mo, and Cr. According to alloy composition characteristics and uses, it is divided into main series such as W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag, etc., with a density as high as 16.5-19.0g/cm3, and Widely known as high specific gravity alloy.

It has a series of excellent characteristics, specific gravity: generally specific gravity is 16.5-18.75g/cm3, high strength: tensile strength is 700-1000Mpa, strong ability to absorb rays: its ability is 30-40% higher than lead, thermal conductivity Large: 5 times that of mold steel; small thermal expansion coefficient: only 1/2-1/3 of iron or steel, good electrical conductivity; good weldability and processability. Usually we will fire a suitable high specific gravity tungsten alloy billet according to the needs, and then make the corresponding finished product that matches the drawing through machining, welding, etc. Of course, we also have mature MIM molding technology that can make smaller and more structural For complex shielding products.

For example:

Geological drilling is one of the commonly used exploration techniques in the oil and gas industry. It works by drilling into underground rock formations, taking samples of the formation, and then analyzing them to determine the presence of oil or natural gas. During geological drilling, gamma ray sources are used to help penetrate rock formations. Gamma rays are high-energy electromagnetic radiation that can penetrate matter and interact with matter during the penetration process to produce secondary particles or change the chemical structure of matter. By using a gamma ray source, detailed information about underground rock formations can be obtained, such as their thickness, type and structure.

In order to protect workers and equipment from gamma ray radiation, high-gravity tungsten alloy products are widely used to shield radioactive sources and as gamma-ray collimators, which can effectively absorb and scatter gamma rays and reduce radiation doses.

In geological drilling, high-gravity tungsten alloy shielding products are often placed around radioactive sources to prevent gamma ray leakage. At the same time, tungsten alloy collimators are used to accurately point to the target to ensure that gamma rays can accurately penetrate underground rock formations.

Additionally, gamma rays have other applications in the oil and gas industry, such as checking weld quality and detecting cracks in pipelines. In these applications, the gamma source is often mounted in a remotely controlled wheeled cart so that it can be operated from a safe distance. Tungsten alloy collimators are used to accurately point gamma rays to the target location. Tungsten Alloys play an important role in geological drilling and are widely used in shielding radioactive sources, as gamma ray collimators and other related applications.

In the nuclear industry, high-gravity tungsten alloy shielding is used to protect workers from the hazards of radioactive radiation. They are usually placed around nuclear reactors, nuclear fuel processing facilities and nuclear medicine facilities to reduce the leakage of radioactive materials and radiation damage to workers.

In the electronics industry, tungsten alloy shields are used to protect electronic equipment and personal safety from electromagnetic interference and radiation. They are usually placed around electronic equipment to prevent electromagnetic interference and radiation from affecting electronic equipment and ensure the normal operation of electronic equipment.

In addition, tungsten alloy shielding parts are also used in medical, aerospace and other fields. For example, in the medical field, tungsten alloy shielding parts are used to protect doctors and patients from the harm of radioactive radiation; in the aerospace field, high-specific gravity tungsten alloy shielding parts are used to protect the safety of aircraft and satellites from electromagnetic interference and radiation. Impact.

Although lead also has shielding properties and is cost-effective and has long been used to store and transport radioactive materials, it poses environmental hazards. In addition, lead with a larger volume component has an effective shielding effect. High specific gravity tungsten alloys can effectively make up for these shortcomings. At the same time, they are environmentally friendly and have a density that is more than 40% higher than lead. Therefore, they are often used in precision Orthogonal isotopes are found in shipping containers, gamma cameras, cobalt teletherapy machines and nuclear reactors. Able to provide a more effective shield using less material.

In short, industrial tungsten alloy shielding is an important protective device that can effectively protect the safety of workers and equipment from radiation and electromagnetic interference.

It is hoped that environmentally friendly materials such as high specific gravity tungsten alloy will be more widely used in the future and make due contributions to the earth's environmental protection cause.
