High Performance High Density Machined Heavy Tungsten Alloy
CrucibleHeavy Tungsten Alloy Crucible is mainly divided into nickel-iron
alloy, nickel-copper alloy, and even nickel-iron-copper alloy. In
contrast, wide nickel-iron alloys have better mechanical properties
and play an important role in the defense industry and various
fields of the national economy. It is a very important new material
in the defense industry and is gradually extended to various
civilian industries. What is Heavy Tungsten Alloy Crucible?Heavy tungsten alloy is a tungsten-based alloy material (tungsten
content is generally 80%~98%), which contains a small amount of
nickel, iron, copper, cobalt, molybdenum, chromium and other
elements. The density of high specific gravity tungsten alloy can
reach 15.20~18.70g/cm3, also known as high specific gravity
tungsten alloy or high density alloy material. Because tungsten
weighs more than twice as much as alloy steel. Heavy duty tungsten alloys are typically produced by mixing the
desired tungsten, iron, nickel or copper powders, then cold
pressing and liquid phase sintering until near full density. During
the liquid phase treatment, the matrix tungsten alloy melts and
part of the tungsten enters the solution, forming a microstructure
of dispersed tungsten particles (20-60 μm).
Chemical composition of Heavy Tungsten Alloy CrucibleChemical Composition | 90%W | 93%W | 95%W | 97%W | Density (g/cc) | 16.85-17.25 | 17.15-17.85 | 17.75-18.35 | 18.25- 18.85 |
Heavy Tungsten Alloy Crucible Picture:
Application of Heavy Tungsten Alloy CrucibleTungsten alloys have replaced lead in military products because
their higher density allows them to retain their shape better, even
under extreme conditions. Although uranium offers comparable
density, its volatility and the special licensing requirements
required for radioactive materials make processing difficult.
Tungsten alloy is a kind of green environmental protection metal
material, in the use and production process will not produce toxic
substances. With the continuous expansion of military industry, the
impact of military weapons on the environment should also be
considered. The environmental performance of tungsten alloy makes
it more and more prominent in the military field. Such as tungsten
alloy tail shell piercing shells, tungsten alloy submarine weight,
tungsten alloy engine accessories and so on.
