WNiCu High Density Rolled Heavy Tungsten Alloy SheetsHeavy 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. Heavy Tungsten Alloy Sheets Picture:

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.
