Machined 95WNiFe High Density Heavy Tungsten Alloy Cubes For
Counterweight
Heavy Tungsten Alloy Cubes has high density, high strength and high
hardness (commonly known as 3H alloy), and has good ductility,
conductivity and thermal conductivity. It plays an important role
in weapon manufacturing. Later, it is widely used in national
defense, aerospace and civil industry (such as electrical,
drilling, etc.). High gravity tungsten alloy materials have become
military and civil alloy materials.

Introduction & Features of Tungsten Alloy Cubes
Tungsten alloy nuggets are mainly divided into two series, W-Ni-Fe
and W-Ni-Cu, and even w-ni-fe-cu. In contrast, W-Ni-Fe alloy has
better mechanical properties and plays a great role in various
departments of national defense industry and national economy. It
is a very important new military material in the national defense
industry, and gradually extends to various civil industries.
The content of tungsten in heavy tungsten alloy is between 90% and
98%, which is the reason for its high density (16.5-19.00 g / CC).
Nickel, iron and / or copper are used as metal binder substrates
for bonding. Fragile tungsten particles together make tungsten
alloys hard and easy to use. Nickel is the most commonly used
additive, including 7Ni: 3Fe or 8ni: 2Fe (by weight).
Application of Heavy Tungsten Alloy Cubes
Application of tungsten alloy
* Nuclear radiation protection screens, such as PET syringe
screens, vial screens, isotope containers, FDG containers,
multi-leaf collimators, etc.
*Balance weights, such as tungsten sinking bars, heavy metal boring
bars, ship crank camshafts, logging brackets, racing weights,
vibration reduction, dynamic balancing weights, etc.
*High voltage electrical contacts
*Electrodes for resistance welding
