High Density WNiCu Rolled Tungsten Heavy Alloy ASTM B777
WNiCu High Density Rolled Heavy Tungsten Alloy Sheets
Heavy Tungsten Alloy Sheets is also known as tungsten alloy plates because they weigh more than twice the weight of iron or steel.High-specific gravity tungsten alloys are usually a refractory metal consisting of two-phase w-Ni-Fe, w-Ni-Cu, and even w-Ni-Cu-Fe composites.Some tungsten alloys add rare earths and / or other metals, such as cobalt, molybdenum, and chromium.Tungsten alloy has a high melting point, twice as dense as steel and more than 50% heavier than lead.
The Heavy Tungsten Alloy Sheets contains 80%-98% tungsten, and contains a small amount of molybdenum, nickel, iron, copper and other elements. After a process of mixing, pressing and sintering, tungsten combines with other metal elements and begins to appear in powder form. With our leading pure tungsten metal plate and plate capabilities, we can provide a range of tungsten heavy alloy plate and tungsten heavy alloy plate products with different thicknesses and lengths, and according to customer requirements. Heavy duty tungsten alloy hot rolled sheet. We have been engaged in pure tungsten and molybdenum hot rolling for more than 80 years and are the only tungsten producer in China with hot rolling capability.

Introduction and characteristics of Heavy Tungsten Alloy Sheets
- The tungsten content of the tungsten-heavy alloy is between 90% and 98%, which is responsible for its high density (16.5 to 19.00g/cc).Nickel, iron, and / or copper are used as a metal adhesive substrate to hold the fragile tungsten particles together, making 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 the tungsten heavy alloy preparation 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 some tungsten is brought into the solution to form a microstructure through which large tungsten particles (20-60 m) are dispersed in the matrix alloy.
Application of Heavy Tungsten Alloy Sheets
- A thermoelectric generator is a fusion energy power generation device using radioactive isotopes.It can use a high-density tungsten alloy as a container.It has been widely used in meteorological stations, optical buoys, acoustic communications beacons, marine research and other fields.
