Tungsten heavy alloy (WHA) is a tungsten-based alloy that contains at least 90% tungsten and 10% other metals such as nickel, iron, and copper. WHA stands out for its great thermal performance, high hardness, large density, and other notable properties. With these desirable features, tungsten heavy alloy found lots of applications including counterweights, radiation shields, etc.

Therefore, this article is going to discuss the features, production methods, and uses of the invaluable tungsten heavy alloy in detail.
Tungsten heavy alloy shares similar properties with pure tungsten.
Additionally, tungsten heavy alloy has several other advantages compared with pure tungsten.

This impressive alloy is widely produced by powder metallurgy (P/M) method—liquid phase sintering (LPS), which can be divided into the following steps.
Finally, we gained WHA products with a unique combination of density, strength, machinability, and economy.
Tungsten heavy alloy is extensively used to make counterweight products for military uses and other fields. These counterweights have a high mass ratio, so you can get larger gravity within a smaller volume. They are also applied to everyday goods. There are lots of mechanical counterweights, weighting rods, and counterweight balls employing tungsten-heavy alloys.

With the development of modern science and technology, more and more radiation devices appear. How to prevent radiation hazards has attracted people’s attention. In order to protect medical workers and common people from the danger of radiation, advanced materials are employed to shield radioactive sources. WHA is one of them. For example, WHA shields are commonly used as radioisotope containers.
Last, let’s talk about military equipment made from tungsten-heavy alloys. It is rather easy to find them in warheads, aircraft shells, bomb shells, ships, tanks, and weapons.
Tungsten heavy alloy is an advanced material with great thermal properties, high density, and radiation absorption ability, and WHA has many applications including counterbalances, radiation shields, military devices, etc. Advanced Refractory Metals (ARM) is a leading supplier of a range of tungsten-heavy alloys.
