The Pure Tungsten Block is a solid block material made of pure tungsten material with a purity of 99.95% or higher. It is generally used in industrial fields with high temperature, high density and high strength requirements.
Applications
Radiation Protection
Due to its high density and atomic number, high-purity tungsten blocks can effectively shield various types of radiation, especially in nuclear energy, radiotherapy, and radiation detection fields. Tungsten blocks are widely used in radiation protection applications, such as preventing radiation leakage in nuclear reactors, X-ray machines, and particle accelerators.
Aerospace
In aerospace, Pure Tungsten Block is used in engine parts, heavy counterweights, and high-temperature materials. Its ability to withstand extreme heat and thermal shock makes it highly suitable for aerospace applications.
Electronics and Electrical Industry
High-purity tungsten blocks are widely used to produce electronic devices, especially components designed to operate in high-temperature and high-pressure environments. These blocks are used in manufacturing vacuum tubes, electrical contacts, bulb electrodes, and more.
Metallurgy and Metal Processing
Thanks to its high melting point and oxidation resistance, tungsten plays a crucial role in high-temperature metal smelting processes, particularly in the processing of refractory metals like titanium and aluminum alloys.
