Polished Alloy WNiFe Tungsten Balls Spheres For Sale WNiFe Tungsten Balls Spheres For Sale has high density, high
strength, high hardness (commonly known as 3H alloy) and good
ductility, electrical conductivity and thermal conductivity and
other comprehensive properties. It plays an important role in
weapon manufacturing and is widely used in national defense
industry, aerospace and civil industry (such as electrical industry
and drilling industry). High specific gravity tungsten alloy
materials have become military and civil alloy materials. WNiFe Tungsten Balls Spheres SPECIFICATION & CHEMICAL

WNiFe Tungsten Balls Spheres Picture:
Introduction and characteristics of WNiFe Tungsten Balls - Tungsten heavy alloys contain between 90% and 98% tungsten, which
is responsible for their high density (16.5 to 19.00g/cc). Nickel,
iron and/or copper are used as metal bonding substrates to hold
fragile tungsten particles together, making tungsten alloys strong
and easy to work with. Nel is the most commonly used additive with
a ratio of 7Ni: 3Fe or 8Ni: 2Fe (weight ratio).
- Common processes for preparing tungsten heavy alloys include mixing
the desired amount of tungsten, iron, nickel or copper powder and
then cold pressing and liquid phase sintering to almost full
density. During the liquid phase treatment, the matrix tungsten
alloy melts, bringing some tungsten into the solution and forming a
microstructure through which large tungsten particles (2060 m)
disperse in the matrix alloy.
Application of WNiFe Tungsten Balls - In the design and development of shell piercing projectile, the
high proportion of tungsten alloy is an effective technical measure
to improve the core kinetic energy and armor piercing ability. In
the 1970s, the opening hours were shorter. At present, in addition
to the high gravity tungsten alloy cores used in the United States,
many Western European countries also use them accordingly.
