Chemical Etching with Tungsten

Tungsten is a refractory metal with the highest melting point of 3422°C among all other known elements, which makes it suitable for applications that operate in extremely high temperatures.

In addition to its exceptional melting point, its high tensile strength and high density make tungsten an ideal material for various applications, such as manufacturing surgical tools, electron guns, X-ray tubes, and radiation shields. Tungsten’s unique properties ensure reliable performance and durability for the devices manufactured using the metal.

We welcome your questions about how to use Tungsten for your parts.

Tungsten is a refractory metal with an incredibly high melting point (3422°C) among all other known elements, which makes it ideal for applications in extremely high temperatures.

Etching many grades of tungsten, including high-purity, copper-tungsten, tungsten-rhenium, thoriated rhenium, and AKS-grade
