Tungsten heavy alloy, also known as high density tungsten alloy, is an alloy material composed of tungsten as the matrix, with a small amount of metal binders such as nickel, copper, iron, cobalt, molybdenum, and chromium. Tungsten alloy with its unique physical and chemical properties, plays a significant role in the field of radiation protection. Firstly, its density is extremely high, far exceeding that of ordinary, which means that under the same volume, tungsten alloy can provide a heavier protective barrier, effectively absorbing and blocking radioactive particles such as X-rays and gamma rays ensuring the safety of the space behind the door. This property allows the radiation protection door to hold the line in the face of high-intensity radiation, protecting personnel radiation damage.
In addition, the environmental friendliness and non-radioactivity of high-density tungsten alloys are also important reasons for their widespread use in radiation-shed doors. It does not contain radioactive elements, does not cause secondary pollution to the environment, and its performance remains stable even after long-term exposure to radiation, the continued effectiveness of the radiation-shielded doors. The production process of tungsten alloys mainly includes mixing, pressing, pre-sintering and debinding,, and vacuum sintering. By precise proportioning and advanced production technology, high-density tungsten alloy materials with excellent performance can be prepared
