Because Heavy Tungsten Alloy Plate has excellent radiation resistance, thermal conductivity, electrical conductivity and corrosion resistance, it is an ideal material for making tungsten heavy metal plates, and can be further used to make tungsten heavy metal targets, tungsten heavy metal thermal elements, and radiation-resistant tungsten alloy plates. The new lead-free shielding components are mainly used for radiation protection in radiology departments such as hospital x-ray rooms and CT rooms. It has a good shielding effect on x-rays and gamma rays.

Heavy tungsten alloy foil is also called tungsten heavy alloys because tungsten alloys weigh more than twice as much as iron or steel. High specific gravity tungsten alloys are usually refractory metals composed of W-Ni-Fe or W-Ni-Cu or even W-Ni-Cu-Fe two-phase composites. Some tungsten alloys with rare earth and/or other metals added, such as cobalt, molybdenum, chromium, and heavy tungsten alloys, have high melting points, twice the density of steel, and are more than 50 percent heavier than lead.

The Heavy Tungsten Alloy Plate is between 90% and 98%, which is responsible for its high density (16.5 ~ 19.00g / CC).Nickel, iron, and / or copper are used as a metal adhesive substrate to hold the fragile tungsten particles together to make the tungsten alloy malleable and easy to process.Iron nickel is the most commonly used additive, with a ratio of 7Ni: 3Fe or 8ni: 2Fe (weight ratio).
Commonused processes for preparing heavy tungsten alloys include mixing required amounts of tungsten, iron, nickel or copper powder followed by cold pressure and liquid phase sintering to almost full density.During the liquid phase treatment, the matrix tungsten alloy is melted and part of the tungsten is brought into the solution to form a microtissue, and large tungsten particles (20 ~ 60 m) are dispersed in the matrix alloy.
