Material page for demister pads (mist eliminators) in Brass. The decorative and spark-resistant screening alloy. Covers the grade designation (H65 / CuZn35), corrosion and magnetic behavior, cleaning and compatibility notes, and the specifications available.
Why Choose Brass for Demister Pads (Mist Eliminators)
The decorative and spark-resistant screening alloy. For demister pads (mist eliminators), this matters when good atmospheric and fresh-water resistance; unsuitable for ammonia service is the controlling requirement.
Alloy Properties
| Grade designation | H65 / CuZn35 |
|---|---|
| Magnetic response | Non-magnetic |
| Service temperature | approx. +200 °C |
| Corrosion characteristic | Good atmospheric and fresh-water resistance; unsuitable for ammonia service |
Corrosion Behavior in Filtration Service
Copper and brass demister pads (mist eliminators) resist atmospheric corrosion and fresh water well, tarnishing to a stable patina. Avoid ammonia and ammonium compounds (stress-corrosion cracking of brass) and strong oxidizing acids. In marine service, phosphor bronze outperforms plain brass.
Comparable Alloys
Within the copper family: brass for economy and appearance, phosphor bronze for fatigue strength and marine air, pure copper where conductivity (EMI shielding) is the point. For structural filtration duties, stainless 304/316 is the usual alternative.
