Properties
The mechanical properties of these alloys, including tensile strength, ductility, and hardness, combined with other elemental metals, create a family of tungsten alloy materials that are highly valued where a dense mass is required in confined spaces. Tungsten alloys ensure the resilience and stability essential for the challenging processes of oil and gas drilling. Tungsten alloys are cost-effectively fabricated using powder metallurgy techniques and are routinely machined through conventional methods. They are available as semi-finished products for further processing by customers or as fully finished machined parts according to customer specifications.
Characteristics and Features
As medical science advances, radiation exposure has become a growing concern, including X-ray radiation, gamma radiation (high-energy electromagnetic radiation), alpha particle radiation (helium atoms), beta particle radiation (electrons), and cosmic radiation, among others. To safeguard patients and the public from the detrimental effects of ionizing radiation, such as breast cancer and skin cancer, the demand for an exceptional radiation-absorbing medium is critical.
Application
Tungsten alloy radiation shields are expertly designed to allow radiation to be focused only where necessary. Our shields ensure minimal environmental radiation exposure during X-ray generation. Due to its exceptional density and shielding properties, tungsten alloy is ideal for protecting adjacent tissue and guiding radiation solely to its intended target, making it widely utilized in both Medical and Industrial Radiation Shielding.
Tungsten alloys require no special licensing and exhibit stability at high temperatures. For equivalent energy absorption, you can use one-third less tungsten alloy than lead, significantly reducing material usage. Moreover, it is a non-toxic option. Utilize our high-density tungsten alloys for effective shielding wherever radiation control and direction are crucial. Xi'an Kefeng Powder Metallurgy Co., Ltd. excels in manufacturing custom tungsten radiation shields tailored to your specifications.
