Tungsten Metal for Shielding

 Tungsten Metal for Shielding
Tungsten metal is a grayish-white lustrous metal that is often brittle and hard to work. Of all metals in pure form, tungsten has highest melting point of all elements except carbon - vary between 3387°C and 3422°C. It also has good thermal and electrical conductivity. Its electrical conductivity at 0°C is about 28% of that of silver which itself has the highest conductivity of all metals. In addition, it has low vapor pressure at high temperatures. Such properties make tungsten metal a high performance material in high temperature products and processes. Tungsten metal powder is used as a filler material in plastic composites, which are used as a nontoxic substitute for lead in bullets, shot, and radiation shields.IF you need tungsten metail shielding, you could contact sales@chinatungste.com.

Tungsten Powder for Radiation Shielding

 Tungsten Powder for Radiation Shielding

Tungsten powders are widely used in the production of weight fillers, radiation shielding fillers, and induction accelerators etc. Thin film surface of its polymer mixture are ideally suited for radiation protection. The large particles make it ideal heavy metal filler for injection-molding applications. The unique shape and resulting high flow ability of these particles make it suitable for metal spray industry applications.
