Frequently Asked Questions

What are the benefits of using photochemical etching to manufacture tungsten parts?

Photochemical etching offers distinct advantages for manufacturing tungsten parts, including precise intricate designs, minimal material waste, and retention of tungsten’s inherent properties without heat-related changes. 

The process also ensures burr-free, stress-free parts with chemical resistance, making it ideal for complex geometries and applications where lightweight, durable components are crucial. 

Furthermore, the process uses a direct digital imager to image on the desired design, which leads to scalability, reduced tooling costs, and rapid turnaround. All these factors contribute to cost-effective mass production and quick prototyping of high-performance tungsten parts.

What is the average turnaround time for tungsten etching projects?

The turnaround times for etching projects can range from 2 to 5 weeks, depending on material availability. We encourage you to contact Elcon for a better idea of how long your specific project may take.  

Are there other etching techniques that can be used for tungsten?

Today, a range of techniques are available to etch tungsten on materials such as glass, stainless steel, and ceramic, including:

  • Dry etching: It’s also known as plasma etching. During the process, the desired material is kept in a device and bombarded with ions (plasma of reactive gases, such as fluorocarbons and oxygen) to create a specific pattern. This is used to manufacture semiconductors or microchips. Examples of dry etching techniques include reactive ion etching (RIE) and inductively coupled plasma (ICP).  
  • Wet etching: It’s also known as chemical etching. In this process, a liquid reactant (that either dissolves or causes oxidation or fluorination of the target element) is used to remove the thin film of tungsten from the material. An example of wet etching is the Electrochemical etching technique.

While these can be ideal techniques for certain situations, photochemical etching offers the most precise, high-quality tungsten components. Connect with the team at Elcon Precision to learn more about this technique.
