Choosing the Right Material for Static Control Emitter Pins

 

In the world of static control, even the smallest components can make a big difference. One crucial element in static control systems is the emitter pin on a static bar, which generates ions to neutralize static charges. At Simco-Ion, tungsten is one of our top choices for the emitter pins used in our premium static bars, including the IQ Power line—and for good reason. Not only do we prioritize ethically sourced tungsten, but an internal study comparing emitter materials highlights how tungsten outperforms other material choices for static control applications.


Pin Wear Study Highlights

To determine the best material for static control emitter pins, we conducted a comprehensive study comparing tungsten, titanium, and stainless steel under high-wear conditions. The study followed a rigorous process:

  • Test Setup: Each fixture was energized with its own positive power supply. Positive polarity was selected to accelerate erosion during the ionization process.
  • Current Regulation: The power supplies were set to a current regulation level of 40 microamps.
  • High-Wear Scenario: A combination of distance to ground, polarity, and current was used to create an environment that accelerated the wear process.
  • Continuous Testing: The test ran continuously, with brief intervals for cleaning and photographing emitter points.

Key Findings

Tungsten 

  • Maintained its tip shape and sharpness with negligible wear, ensuring peak performance throughout the study.    

Titanium                                                                                                                                     

  • Experienced moderate tip erosion, reducing its long-term performance and requiring more frequent maintenance.

Stainless Steel              

  • Showed significant wear, with noticeable rounding and performance degradation early in the test.

This detailed methodology highlights tungsten’s resilience under extreme conditions, proving it is the most durable material for emitter pins.

   


Key Advantages of Tungsten         

1. Superior Hardness and Durability

Tungsten is one of the hardest materials available, significantly outlasting titanium in wear resistance. Its hardness ensures emitter pins remain durable even in demanding industrial environments, reducing the need for replacements.

2. Exceptional Shape Retention

The sharpness of emitter pins is vital for efficient ionization. Tungsten’s unmatched wear resistance allows it to retain its edge longer than titanium, ensuring:

  • Higher ion generation efficiency
  • Lower voltage requirements
  • Consistent ion output over time

This durability minimizes downtime and keeps static control systems operating at peak efficiency.

3. Outstanding Corrosion Resistance

In environments with exposure to moisture or chemicals, tungsten’s corrosion resistance ensures a longer lifespan without degradation.

4. Heat Resistance for Stability

Tungsten’s high melting point and resistance to thermal expansion make it ideal for extreme temperatures. It maintains its shape and performance, providing stability in your demanding application.

5. Long-Term Cost-Effectiveness

While tungsten may have a higher upfront cost than titanium, its extended lifespan, reduced maintenance needs, and fewer replacements make it a cost-effective solution. Over time, tungsten saves both time and money by reducing operational disruptions.
